How To : The Best Investigatory Projects in Science: 16 Fun & Easy Ideas to Kickstart Your Project

The Best Investigatory Projects in Science: 16 Fun & Easy Ideas to Kickstart Your Project

Most of us have conducted an investigatory science project without even knowing it, or at least without knowing that's what it was called. Most science experiments performed, from elementary to high school students and all the way up to professional scientists, are investigatory projects.

What's an Investigatory Project Exactly?

An investigatory project is basically any science experiment where you start with an issue or problem and conduct research or an investigation to decide what you think the outcome will be. After you've created your hypothesis or proposal, you can conduct a controlled experiment using the scientific method to arrive at a conclusion.

What's the Scientific Method?

For those of us who have forgotten the various steps of the scientific method, let me clear that up right here:

The Best Investigatory Projects in Science: 16 Fun & Easy Ideas to Kickstart Your Project

Remember, however, that a successful investigatory science project does not necessarily have to result in the intended outcome. The purpose of these projects is to think critically, and if the solution doesn't work out, that doesn't mean your project will fail.

What Kind of Investigatory Projects Are There?

In order to conduct a great investigatory experiment, you have to ask an interesting question and be able to conduct an experiment that can hopefully answer that question. The harder and more intriguing the initial question is, the better the resulting investigation and experiment will be.

I've listed a few examples below of some of the best investigatory experiments out there, so hopefully you'll have no problem coming up with an idea.

Project #1: Making Soap Out of Guava

Basic hygiene should be available to everyone, but what about people who live in areas without easy access to grocery stores or pharmacies? This is a great question that makes you think about scientific alternatives to store-bought soap.

Below is an example project that creates soap from guava leaf extract and sodium hydroxide, but there's no shortage of materials you can use to replace the guava, like coconut oil or a fat like lard, butter or even the grease from your kitchen .

Project #2: Used Cooking Oil as a Substitute for Diesel

We all know how lucrative the oil business is, but what if the next huge innovation in oil was sitting right inside your kitchen cabinet? With the high prices of regular gasoline and diesel fuel, the possibility of creating a usable diesel fuel from household cooking oils is pretty exciting.

Although creating diesel fuel out of cooking oils that will run a BMW may sound like a reach, it still makes for a great project. And who knows, maybe in doing this you'll actually figure out what was missing from previous attempts . Being an instant billionaire doesn't sound too bad to me.

The Best Investigatory Projects in Science: 16 Fun & Easy Ideas to Kickstart Your Project

If you're interested in trying it for yourself, there's a great step-by-step guide with a full ingredients list and photos over on Make .

Project #3: Create Another Alternative Fuel

If biodiesel isn't your forte, you can try making oxyhydrogen gas or creating hydrogen gas via electrolysis or vice versa, creating electricity from hydrogen gas .

The Best Investigatory Projects in Science: 16 Fun & Easy Ideas to Kickstart Your Project

Project #4: Purifying Used Cooking Oil

Speaking of oil, if you use it to cook, you know that a lot of it goes to waste. But what if you could clean that oil and use it over and over again? Not only would that save money, but it would also benefit the environment since most people do not properly dispose of used cooking oil (no, pouring it down the drain doesn't count).

Your project goal would be to research methods of filtration or purification and test it on cooking oils. To easily demonstrate which method works best, try cooking some food in the oil produced by each one. Good food can go a long way when it comes to winning people over.

Check out the abstract and description of a similar project here .

Project #5: Alternative Methods of Producing Iodized Salt

In areas isolated from the sea, IDD or Iodine Deficiency Disease, is very common. Since these areas do not have easy access to marine foods or grocery stores, the population becomes very susceptible to the disease due to a lack of iodine in the diet. In order to combat this, researchers and doctors have begun infusing iodine into regular table salts.

If not iodine is readily available, it can be chemically made either with sulfuric acid and alkali metal iodide or hydrochloric acid and hydroxide peroxide .

But perhaps there are other more accessible ways to create an iodized salt that people could make at home. For a starting point, take a look at this previous experiment .

Project #6: Making Biodegradable Plastic

Plastic bags are actually illegal in Santa Monica , CA (and soon to be Los Angeles ) because of their threat to the environment due to insane resistance to biodegradation. I didn't think they were that bad, but one plastic bag can take up to 1,000 years to break down completely, and it can even ruin your car along the way. So, creating a better biodegradable plastic bag would be a huge achievement.

The Best Investigatory Projects in Science: 16 Fun & Easy Ideas to Kickstart Your Project

The only question is how one would go about doing so, and what materials could be used? That's the question you can answer for your project. This project used cassava starch as an effective component for a biodegradable plastic, but you could try using a few different starches and see what works best.

Project #7: Solar Water Purification

One of the biggest world problems is finding clean water. While we in the states can find purified or drinkable tap water almost anywhere, millions of people around the world don't have access to clean drinking water.

A few students decided to investigate a potential purification process using the sun's energy and an aluminum sheet. Watch the video below for more information and a complete walkthrough of their scientific process.

And if you're an overachiever, you can step it up a notch and try purifying pee instead .

Project #8: Perfecting the Paper Bridge

Of course, an investigatory project doesn't always have to answer such grand questions. This experiment looks to discover how to build the strongest paper bridge by varying how the pieces are held together. So, the question is, "How do design changes affect a load bearing structure?"

The Best Investigatory Projects in Science: 16 Fun & Easy Ideas to Kickstart Your Project

Check out the video below for more information on replicating the project yourself.

Project #9: Making Instant Ice

It's summer time and the degrees are already hitting triple digits in some areas. When it's this hot, there are few things better than a glass of ice chilled water or lemonade. But what happens if you don't have ice? Can you create your own ice or cool drinks quickly by another method? Check out this clip from King of Random .

Cool, huh? But how does it work? Is there any other way to replicate this? Well, let the investigation begin. Figure out what your hypotheses will be and follow along with this video for you own investigatory project.

For more information and additional photos, be sure to check out the King of Random's full tutorial .

Project #10: Increase the Shelf-Life of Fruits and Veggies

Extending the shelf-life of perishable fruits and vegetables can make a huge difference for small farmers, street-side vendors and even your average Joe—groceries aren't cheap. What is an inexpensive and easily accessible way to make produce stay fresh longer?

The Best Investigatory Projects in Science: 16 Fun & Easy Ideas to Kickstart Your Project

That's the question behind this great investigatory science project featured here . While these researchers focused exclusively on chitosan coating on bananas, you can branch out (no pun intended) and try an assortment of other fruits, veggies and possible coating materials.

For more information on how to keep your fruits and vegetables fresh for longer, check out my previous article , or Yumi's recent illustration for other ideas.

Project #11: Slow the Ripening of Sliced or Chopped Produce

You could also focus your project on keeping fruits and vegetables from browning after they've already been cut up. There are various methods and materials you can use to slow down the ripening process, such as honey and lemon juice. Watch the video below and read this tutorial for more information and ideas.

Your project could revolve around finding the best option, and testing out some of your own browning-prevention solutions to see if you can come up with a better one.

Project #12: Improve Memory by Thinking Dirty

If my memory was any good I would be fluent in Spanish and never need to look up the Quadratic Formula again. But my problems are more superficial, like forgetting where I put my keys or what time my dentist appointment was supposed to be. There are folks out there who do suffer from real memory problems, so figuring out how to help improve memory makes for a great investigatory project.

The Best Investigatory Projects in Science: 16 Fun & Easy Ideas to Kickstart Your Project

There are tons of studies on memory and memory loss that you can research. But for your investigatory science project, you will want to come up with your own hypothesis based on that information and test it out. Does using colors to form associations help with memory? Does linking an image with a memory increase its hold in the carrier's head? What about drinking grape juice or sniffing rosemary ? These are the types of questions you may look to answer.

This article contends that memory can be improved by looking at NSFW images or thinking of dirty associations. Come up with your own theory and let the brain hacking begin.

Project #13: Improving Social Anxiety by Manipulating the Body & Mind

Science experiments don't always have to include chemicals or test tubes. The science of the mind can be just as interesting. So what's the investigation consist of?

Can you truly affect the way you act and feel by simply changing your posture? Does acting a certain way manipulate the mind drastically enough to actually change the way you feel?

Check out Amy Cuddy's awesome TED Talk for more ideas for additional questions you could ask.

Project #14: Kitchen DNA Extraction

You may think studying DNA is only for professionals with super expensive lab equipment, but you can actually extract DNA from any living thing with a few basic ingredients you probably have in your kitchen like dish soap and rubbing alcohol.

The Best Investigatory Projects in Science: 16 Fun & Easy Ideas to Kickstart Your Project

Decide on something to vary, like different fruits and vegetables or types of dish soap, and come up with a hypothesis regarding which will allow you to collect the most DNA material.

You can also find more information, as well as another way to perform the experiment, here .

Project #15: Make Homemade Glue from Milk

With milk, white vinegar and baking soda, you can make your own glue right at home. Make it an investigatory project by changing up the recipe and testing which results in the strongest glue. You could also try varying the ingredients to make it dry faster, or work on different materials (wood vs. plastic vs. paper).

The Best Investigatory Projects in Science: 16 Fun & Easy Ideas to Kickstart Your Project

Project #16: Make a Battery Out of Fruits and Vegetables

How can you power a small light or device without electricity? You can make a DIY battery with a few different types of fruits and vegetables. Anything from a lemon to an apple , potato , or even passion fruit will work.

The Best Investigatory Projects in Science: 16 Fun & Easy Ideas to Kickstart Your Project

Pick a few different fruits or vegetables and form a hypothesis as to which will make the battery that puts out the most energy or lasts the longest. Once you've built your batteries, hook up a volt meter to read the output and see which one is the best.

Seventy-Five Scientific Research Projects You Can Contribute to Online

From astrophysicists to entomologists, many researchers need the help of citizen scientists to sift through immense data collections

Citizen science (mobile)

Rachael Lallensack

Former Assistant Editor, Science and Innovation

If you find yourself tired of streaming services, reading the news or video-chatting with friends, maybe you should consider becoming a citizen scientist. Though it’s true that many field research projects are paused , hundreds of scientists need your help sifting through wildlife camera footage and images of galaxies far, far away, or reading through diaries and field notes from the past.

Plenty of these tools are free and easy enough for children to use. You can look around for projects yourself on Smithsonian Institution’s citizen science volunteer page , National Geographic ’s list of projects and CitizenScience.gov ’s catalog of options. Zooniverse is a platform for online-exclusive projects , and Scistarter allows you to restrict your search with parameters, including projects you can do “on a walk,” “at night” or “on a lunch break.”

To save you some time, Smithsonian magazine has compiled a collection of dozens of projects you can take part in from home.

American Wildlife

If being home has given you more time to look at wildlife in your own backyard, whether you live in the city or the country, consider expanding your view, by helping scientists identify creatures photographed by camera traps. Improved battery life, motion sensors, high-resolution and small lenses have made camera traps indispensable tools for conservation.These cameras capture thousands of images that provide researchers with more data about ecosystems than ever before.

Smithsonian Conservation Biology Institute’s eMammal platform , for example, asks users to identify animals for conservation projects around the country. Currently, eMammal is being used by the Woodland Park Zoo ’s Seattle Urban Carnivore Project, which studies how coyotes, foxes, raccoons, bobcats and other animals coexist with people, and the Washington Wolverine Project, an effort to monitor wolverines in the face of climate change. Identify urban wildlife for the Chicago Wildlife Watch , or contribute to wilderness projects documenting North American biodiversity with The Wilds' Wildlife Watch in Ohio , Cedar Creek: Eyes on the Wild in Minnesota , Michigan ZoomIN , Western Montana Wildlife and Snapshot Wisconsin .

"Spend your time at home virtually exploring the Minnesota backwoods,” writes the lead researcher of the Cedar Creek: Eyes on the Wild project. “Help us understand deer dynamics, possum populations, bear behavior, and keep your eyes peeled for elusive wolves!"

A baby elephant stands between the legs of an adult elephant.

If being cooped up at home has you daydreaming about traveling, Snapshot Safari has six active animal identification projects. Try eyeing lions, leopards, cheetahs, wild dogs, elephants, giraffes, baobab trees and over 400 bird species from camera trap photos taken in South African nature reserves, including De Hoop Nature Reserve and Madikwe Game Reserve .

With South Sudan DiversityCam , researchers are using camera traps to study biodiversity in the dense tropical forests of southwestern South Sudan. Part of the Serenegeti Lion Project, Snapshot Serengeti needs the help of citizen scientists to classify millions of camera trap images of species traveling with the wildebeest migration.

Classify all kinds of monkeys with Chimp&See . Count, identify and track giraffes in northern Kenya . Watering holes host all kinds of wildlife, but that makes the locales hotspots for parasite transmission; Parasite Safari needs volunteers to help figure out which animals come in contact with each other and during what time of year.

Mount Taranaki in New Zealand is a volcanic peak rich in native vegetation, but native wildlife, like the North Island brown kiwi, whio/blue duck and seabirds, are now rare—driven out by introduced predators like wild goats, weasels, stoats, possums and rats. Estimate predator species compared to native wildlife with Taranaki Mounga by spotting species on camera trap images.

The Zoological Society of London’s (ZSL) Instant Wild app has a dozen projects showcasing live images and videos of wildlife around the world. Look for bears, wolves and lynx in Croatia ; wildcats in Costa Rica’s Osa Peninsula ; otters in Hampshire, England ; and both black and white rhinos in the Lewa-Borana landscape in Kenya.

Under the Sea

Researchers use a variety of technologies to learn about marine life and inform conservation efforts. Take, for example, Beluga Bits , a research project focused on determining the sex, age and pod size of beluga whales visiting the Churchill River in northern Manitoba, Canada. With a bit of training, volunteers can learn how to differentiate between a calf, a subadult (grey) or an adult (white)—and even identify individuals using scars or unique pigmentation—in underwater videos and images. Beluga Bits uses a “ beluga boat ,” which travels around the Churchill River estuary with a camera underneath it, to capture the footage and collect GPS data about the whales’ locations.

Many of these online projects are visual, but Manatee Chat needs citizen scientists who can train their ear to decipher manatee vocalizations. Researchers are hoping to learn what calls the marine mammals make and when—with enough practice you might even be able to recognize the distinct calls of individual animals.

Several groups are using drone footage to monitor seal populations. Seals spend most of their time in the water, but come ashore to breed. One group, Seal Watch , is analyzing time-lapse photography and drone images of seals in the British territory of South Georgia in the South Atlantic. A team in Antarctica captured images of Weddell seals every ten minutes while the seals were on land in spring to have their pups. The Weddell Seal Count project aims to find out what threats—like fishing and climate change—the seals face by monitoring changes in their population size. Likewise, the Año Nuevo Island - Animal Count asks volunteers to count elephant seals, sea lions, cormorants and more species on a remote research island off the coast of California.

With Floating Forests , you’ll sift through 40 years of satellite images of the ocean surface identifying kelp forests, which are foundational for marine ecosystems, providing shelter for shrimp, fish and sea urchins. A project based in southwest England, Seagrass Explorer , is investigating the decline of seagrass beds. Researchers are using baited cameras to spot commercial fish in these habitats as well as looking out for algae to study the health of these threatened ecosystems. Search for large sponges, starfish and cold-water corals on the deep seafloor in Sweden’s first marine park with the Koster seafloor observatory project.

The Smithsonian Environmental Research Center needs your help spotting invasive species with Invader ID . Train your eye to spot groups of organisms, known as fouling communities, that live under docks and ship hulls, in an effort to clean up marine ecosystems.

If art history is more your speed, two Dutch art museums need volunteers to start “ fishing in the past ” by analyzing a collection of paintings dating from 1500 to 1700. Each painting features at least one fish, and an interdisciplinary research team of biologists and art historians wants you to identify the species of fish to make a clearer picture of the “role of ichthyology in the past.”

Interesting Insects

Notes from Nature is a digitization effort to make the vast resources in museums’ archives of plants and insects more accessible. Similarly, page through the University of California Berkeley’s butterfly collection on CalBug to help researchers classify these beautiful critters. The University of Michigan Museum of Zoology has already digitized about 300,000 records, but their collection exceeds 4 million bugs. You can hop in now and transcribe their grasshopper archives from the last century . Parasitic arthropods, like mosquitos and ticks, are known disease vectors; to better locate these critters, the Terrestrial Parasite Tracker project is working with 22 collections and institutions to digitize over 1.2 million specimens—and they’re 95 percent done . If you can tolerate mosquito buzzing for a prolonged period of time, the HumBug project needs volunteers to train its algorithm and develop real-time mosquito detection using acoustic monitoring devices. It’s for the greater good!

For the Birders

Birdwatching is one of the most common forms of citizen science . Seeing birds in the wilderness is certainly awe-inspiring, but you can birdwatch from your backyard or while walking down the sidewalk in big cities, too. With Cornell University’s eBird app , you can contribute to bird science at any time, anywhere. (Just be sure to remain a safe distance from wildlife—and other humans, while we social distance ). If you have safe access to outdoor space—a backyard, perhaps—Cornell also has a NestWatch program for people to report observations of bird nests. Smithsonian’s Migratory Bird Center has a similar Neighborhood Nest Watch program as well.

Birdwatching is easy enough to do from any window, if you’re sheltering at home, but in case you lack a clear view, consider these online-only projects. Nest Quest currently has a robin database that needs volunteer transcribers to digitize their nest record cards.

You can also pitch in on a variety of efforts to categorize wildlife camera images of burrowing owls , pelicans , penguins (new data coming soon!), and sea birds . Watch nest cam footage of the northern bald ibis or greylag geese on NestCams to help researchers learn about breeding behavior.

Or record the coloration of gorgeous feathers across bird species for researchers at London’s Natural History Museum with Project Plumage .

Pretty Plants

If you’re out on a walk wondering what kind of plants are around you, consider downloading Leafsnap , an electronic field guide app developed by Columbia University, the University of Maryland and the Smithsonian Institution. The app has several functions. First, it can be used to identify plants with its visual recognition software. Secondly, scientists can learn about the “ the ebb and flow of flora ” from geotagged images taken by app users.

What is older than the dinosaurs, survived three mass extinctions and still has a living relative today? Ginko trees! Researchers at Smithsonian’s National Museum of Natural History are studying ginko trees and fossils to understand millions of years of plant evolution and climate change with the Fossil Atmospheres project . Using Zooniverse, volunteers will be trained to identify and count stomata, which are holes on a leaf’s surface where carbon dioxide passes through. By counting these holes, or quantifying the stomatal index, scientists can learn how the plants adapted to changing levels of carbon dioxide. These results will inform a field experiment conducted on living trees in which a scientist is adjusting the level of carbon dioxide for different groups.

Help digitize and categorize millions of botanical specimens from natural history museums, research institutions and herbaria across the country with the Notes from Nature Project . Did you know North America is home to a variety of beautiful orchid species? Lend botanists a handby typing handwritten labels on pressed specimens or recording their geographic and historic origins for the New York Botanical Garden’s archives. Likewise, the Southeastern U.S. Biodiversity project needs assistance labeling pressed poppies, sedums, valerians, violets and more. Groups in California , Arkansas , Florida , Texas and Oklahoma all invite citizen scientists to partake in similar tasks.

A group of Harvard computers and astronomers.

Historic Women in Astronomy

Become a transcriber for Project PHaEDRA and help researchers at the Harvard-Smithsonian Center for Astrophysics preserve the work of Harvard’s women “computers” who revolutionized astronomy in the 20th century. These women contributed more than 130 years of work documenting the night sky, cataloging stars, interpreting stellar spectra, counting galaxies, and measuring distances in space, according to the project description .

More than 2,500 notebooks need transcription on Project PhaEDRA - Star Notes . You could start with Annie Jump Cannon , for example. In 1901, Cannon designed a stellar classification system that astronomers still use today. Cecilia Payne discovered that stars are made primarily of hydrogen and helium and can be categorized by temperature. Two notebooks from Henrietta Swan Leavitt are currently in need of transcription. Leavitt, who was deaf, discovered the link between period and luminosity in Cepheid variables, or pulsating stars, which “led directly to the discovery that the Universe is expanding,” according to her bio on Star Notes .

Volunteers are also needed to transcribe some of these women computers’ notebooks that contain references to photographic glass plates . These plates were used to study space from the 1880s to the 1990s. For example, in 1890, Williamina Flemming discovered the Horsehead Nebula on one of these plates . With Star Notes, you can help bridge the gap between “modern scientific literature and 100 years of astronomical observations,” according to the project description . Star Notes also features the work of Cannon, Leavitt and Dorrit Hoffleit , who authored the fifth edition of the Bright Star Catalog, which features 9,110 of the brightest stars in the sky.

Microscopic Musings

Electron microscopes have super-high resolution and magnification powers—and now, many can process images automatically, allowing teams to collect an immense amount of data. Francis Crick Institute’s Etch A Cell - Powerhouse Hunt project trains volunteers to spot and trace each cell’s mitochondria, a process called manual segmentation. Manual segmentation is a major bottleneck to completing biological research because using computer systems to complete the work is still fraught with errors and, without enough volunteers, doing this work takes a really long time.

For the Monkey Health Explorer project, researchers studying the social behavior of rhesus monkeys on the tiny island Cayo Santiago off the southeastern coast of Puerto Rico need volunteers to analyze the monkeys’ blood samples. Doing so will help the team understand which monkeys are sick and which are healthy, and how the animals’ health influences behavioral changes.

Using the Zooniverse’s app on a phone or tablet, you can become a “ Science Scribbler ” and assist researchers studying how Huntington disease may change a cell’s organelles. The team at the United Kingdom's national synchrotron , which is essentially a giant microscope that harnesses the power of electrons, has taken highly detailed X-ray images of the cells of Huntington’s patients and needs help identifying organelles, in an effort to see how the disease changes their structure.

Oxford University’s Comprehensive Resistance Prediction for Tuberculosis: an International Consortium—or CRyPTIC Project , for short, is seeking the aid of citizen scientists to study over 20,000 TB infection samples from around the world. CRyPTIC’s citizen science platform is called Bash the Bug . On the platform, volunteers will be trained to evaluate the effectiveness of antibiotics on a given sample. Each evaluation will be checked by a scientist for accuracy and then used to train a computer program, which may one day make this process much faster and less labor intensive.

Out of This World

If you’re interested in contributing to astronomy research from the comfort and safety of your sidewalk or backyard, check out Globe at Night . The project monitors light pollution by asking users to try spotting constellations in the night sky at designated times of the year . (For example, Northern Hemisphere dwellers should look for the Bootes and Hercules constellations from June 13 through June 22 and record the visibility in Globe at Night’s app or desktop report page .)

For the amateur astrophysicists out there, the opportunities to contribute to science are vast. NASA's Wide-field Infrared Survey Explorer (WISE) mission is asking for volunteers to search for new objects at the edges of our solar system with the Backyard Worlds: Planet 9 project .

Galaxy Zoo on Zooniverse and its mobile app has operated online citizen science projects for the past decade. According to the project description, there are roughly one hundred billion galaxies in the observable universe. Surprisingly, identifying different types of galaxies by their shape is rather easy. “If you're quick, you may even be the first person to see the galaxies you're asked to classify,” the team writes.

With Radio Galaxy Zoo: LOFAR , volunteers can help identify supermassive blackholes and star-forming galaxies. Galaxy Zoo: Clump Scout asks users to look for young, “clumpy” looking galaxies, which help astronomers understand galaxy evolution.

If current events on Earth have you looking to Mars, perhaps you’d be interested in checking out Planet Four and Planet Four: Terrains —both of which task users with searching and categorizing landscape formations on Mars’ southern hemisphere. You’ll scroll through images of the Martian surface looking for terrain types informally called “spiders,” “baby spiders,” “channel networks” and “swiss cheese.”

Gravitational waves are telltale ripples in spacetime, but they are notoriously difficult to measure. With Gravity Spy , citizen scientists sift through data from Laser Interferometer Gravitational­-Wave Observatory, or LIGO , detectors. When lasers beamed down 2.5-mile-long “arms” at these facilities in Livingston, Louisiana and Hanford, Washington are interrupted, a gravitational wave is detected. But the detectors are sensitive to “glitches” that, in models, look similar to the astrophysical signals scientists are looking for. Gravity Spy teaches citizen scientists how to identify fakes so researchers can get a better view of the real deal. This work will, in turn, train computer algorithms to do the same.

Similarly, the project Supernova Hunters needs volunteers to clear out the “bogus detections of supernovae,” allowing researchers to track the progression of actual supernovae. In Hubble Space Telescope images, you can search for asteroid tails with Hubble Asteroid Hunter . And with Planet Hunters TESS , which teaches users to identify planetary formations, you just “might be the first person to discover a planet around a nearby star in the Milky Way,” according to the project description.

Help astronomers refine prediction models for solar storms, which kick up dust that impacts spacecraft orbiting the sun, with Solar Stormwatch II. Thanks to the first iteration of the project, astronomers were able to publish seven papers with their findings.

With Mapping Historic Skies , identify constellations on gorgeous celestial maps of the sky covering a span of 600 years from the Adler Planetarium collection in Chicago. Similarly, help fill in the gaps of historic astronomy with Astronomy Rewind , a project that aims to “make a holistic map of images of the sky.”

research project science experiment ideas

Psychology experiments can run the gamut from simple to complex. Students are often expected to design—and sometimes perform—their own experiments, but finding great experiment ideas can be a little challenging. Fortunately, inspiration is all around if you know where to look—from your textbooks to the questions that you have about your own life.

Always discuss your idea with your instructor before beginning your experiment—particularly if your research involves human participants. (Note: You'll probably need to submit a proposal and get approval from your school's institutional review board.)

At a Glance

If you are looking for an idea for psychology experiments, start your search early and make sure you have the time you need. Doing background research, choosing an experimental design, and actually performing your experiment can be quite the process. Keep reading to find some great psychology experiment ideas that can serve as inspiration. You can then find ways to adapt these ideas for your own assignments.

15 Ideas for Psychology Experiments

Most of these experiments can be performed easily at home or at school. That said, you will need to find out if you have to get approval from your teacher or from an institutional review board before getting started.

The following are some questions you could attempt to answer as part of a psychological experiment:

  • Are people really able to "feel like someone is watching" them ? Have some participants sit alone in a room and have them note when they feel as if they are being watched. Then, see how those results line up to your own record of when participants were actually being observed.
  • Can certain colors improve learning ? You may have heard teachers or students claim that printing text on green paper helps students read better, or that yellow paper helps students perform better on math exams. Design an experiment to see whether using a specific color of paper helps improve students' scores on math exams.
  • Can color cause physiological reactions ? Perform an experiment to determine whether certain colors cause a participant's blood pressure to rise or fall.
  • Can different types of music lead to different physiological responses ? Measure the heart rates of participants in response to various types of music to see if there is a difference.
  • Can smelling one thing while tasting another impact a person's ability to detect what the food really is ? Have participants engage in a blind taste test where the smell and the food they eat are mismatched. Ask the participants to identify the food they are trying and note how accurate their guesses are.
  • Could a person's taste in music offer hints about their personality ? Previous research has suggested that people who prefer certain styles of music tend to exhibit similar  personality traits. Administer a personality assessment and survey participants about their musical preferences and examine your results.
  • Do action films cause people to eat more popcorn and candy during a movie ? Have one group of participants watch an action movie, and another group watch a slow-paced drama. Compare how much popcorn is consumed by each group.
  • Do colors really impact moods ? Investigate to see if the  color blue makes people feel calm, or if the color red leaves them feeling agitated.
  • Do creative people see  optical illusions  differently than more analytical people ? Have participants complete an assessment to measure their level of creative thinking. Then ask participants to look at optical illusions and note what they perceive.
  • Do people rate individuals with perfectly symmetrical faces as more beautiful than those with asymmetrical faces ? Create sample cards with both symmetrical and asymmetrical faces and ask participants to rate the attractiveness of each picture.
  • Do people who use social media exhibit signs of addiction ? Have participants complete an assessment of their social media habits, then have them complete an addiction questionnaire.
  • Does eating breakfast help students do better in school ? According to some, eating breakfast can have a beneficial influence on school performance. For your experiment, you could compare the test scores of students who ate breakfast to those who did not.
  • Does sex influence short-term memory ? You could arrange an experiment that tests whether men or women are better at remembering specific types of information.
  • How likely are people to conform in groups ? Try this experiment to see what percentage of people are likely to conform . Enlist confederates to give the wrong response to a math problem and then see if the participants defy or conform to the rest of the group.
  • How much information can people store in short-term memory ? Have participants study a word list and then test their memory. Try different versions of the experiment to see which memorization strategies, like chunking or mnemonics, are most effective.

Once you have an idea, the next step is to learn more about  how to conduct a psychology experiment .

Psychology Experiments on Your Interests

If none of the ideas in the list above grabbed your attention, there are other ways to find inspiration for your psychology experiments.

How do you come up with good psychology experiments? One of the most effective approaches is to look at the various problems, situations, and questions that you are facing in your own life.

You can also think about the things that interest you. Start by considering the topics you've studied in class thus far that have really piqued your interest. Then, whittle the list down to two or three major areas within psychology that seem to interest you the most.

From there, make a list of questions you have related to the topic. Any of these questions could potentially serve as an experiment idea.

Use Textbooks for Inspiration for Psychology Experiments

Your psychology textbooks are another excellent source you can turn to for experiment ideas. Choose the chapters or sections that you find particularly interesting—perhaps it's a chapter on  social psychology  or a section on child development.

Start by browsing the experiments discussed in your book. Then think of how you could devise an experiment related to some of the questions your text asks. The reference section at the back of your textbook can also serve as a great source for additional reference material.

Discuss Psychology Experiments with Other Students

It can be helpful to brainstorm with your classmates to gather outside ideas and perspectives. Get together with a group of students and make a list of interesting ideas, subjects, or questions you have.

The information from your brainstorming session can serve as a basis for your experiment topic. It's also a great way to get feedback on your own ideas and to determine if they are worth exploring in greater depth.

Study Classic Psychology Experiments

Taking a closer look at a classic psychology experiment can be an excellent way to trigger some unique and thoughtful ideas of your own. To start, you could try conducting your own version of a famous experiment or even updating a classic experiment to assess a slightly different question.

Famous Psychology Experiments

Examples of famous psychology experiments that might be a source of further questions you'd like to explore include:

  • Marshmallow test experiments
  • Little Albert experiment
  • Hawthorne effect experiments
  • Bystander effect experiments
  • Robbers Cave experiments
  • Halo effect experiments
  • Piano stairs experiment
  • Cognitive dissonance experiments
  • False memory experiments

You might not be able to replicate an experiment exactly (lots of classic psychology experiments have ethical issues that would preclude conducting them today), but you can use well-known studies as a basis for inspiration.

Review the Literature on Psychology Experiments

If you have a general idea about what topic you'd like to experiment, you might want to spend a little time doing a brief literature review before you start designing. In other words, do your homework before you invest too much time on an idea.

Visit your university library and find some of the best books and articles that cover the particular topic you are interested in. What research has already been done in this area? Are there any major questions that still need to be answered? What were the findings of previous psychology experiments?

Tackling this step early will make the later process of writing the introduction  to your  lab report  or research paper much easier.

Ask Your Instructor About Ideas for Psychology Experiments

If you have made a good effort to come up with an idea on your own but you're still feeling stumped, it might help to talk to your instructor. Ask for pointers on finding a good experiment topic for the specific assignment. You can also ask them to suggest some other ways you could generate ideas or inspiration.

While it can feel intimidating to ask for help, your instructor should be more than happy to provide some guidance. Plus, they might offer insights that you wouldn't have gathered on your own. Your instructor probably has lots of ideas for psychology experiments that would be worth exploring.

If you need to design or conduct psychology experiments, there are plenty of great ideas (both old and new) for you to explore. Consider an idea from the list above or turn some of your own questions about the human mind and behavior into an experiment.

Before you dive in, make sure that you are observing the guidelines provided by your instructor and always obtain the appropriate permission before conducting any research with human or animal subjects.

Frequently Asked Questions

Finding a topic for a research paper is much like finding an idea for an experiment. Start by considering your own interests, or browse though your textbooks for inspiration. You might also consider looking at online news stories or journal articles as a source of inspiration.

Three of the most classic social psychology experiments are:

  • The Asch Conformity Experiment : This experiment involved seeing if people would conform to group pressure when rating the length of a line.
  • The Milgram Obedience Experiment : This experiment involved ordering participants to deliver what they thought was a painful shock to another person.
  • The Stanford Prison Experiment : This experiment involved students replicating a prison environment to see how it would affect participant behavior.

Quick Ideas | Experiment Ideas | Designing Your Experiment | Types of Research

If you are taking a psychology class, you might at some point be asked to design an imaginary experiment or perform an experiment or study. The idea you ultimately choose to use for your psychology experiment may depend upon the number of participants you can find, the time constraints of your project, and limitations in the materials available to you.

Consider these factors before deciding which psychology experiment idea might work for your project.

This article discusses some ideas you might try if you need to perform a psychology experiment or study.

Table of Contents

A Quick List of Experiment Ideas

If you are looking for a quick experiment idea that would be easy to tackle, the following might be some research questions you want to explore:

  • How many items can people hold in short-term memory ?
  • Are people with a Type A personality more stressed than those with a Type B personality?
  • Does listening to upbeat music increase heart rate?
  • Are men or women better at detecting emotions ?
  • Are women or men more likely to experience imposter syndrome ?
  • Will students conform if others in the group all share an opinion that is different from their own?
  • Do people’s heartbeat or breathing rates change in response to certain colors?
  • How much do people rely on nonverbal communication to convey information in a conversation?
  • Do people who score higher on measures of emotional intelligence also score higher on measures of overall well-being?
  • Do more successful people share certain personality traits ?

Most of the following ideas are easily conducted with a small group of participants, who may likely be your classmates. Some of the psychology experiment or study ideas you might want to explore:

Sleep and Short-Term Memory

Does sleep deprivation have an impact on short-term memory ?

Ask participants how much sleep they got the night before and then conduct a task to test short-term memory for items on a list.

Social Media and Mental Health

Is social media usage linked to anxiety or depression?

Ask participants about how many hours a week they use social media sites and then have them complete a depression and anxiety assessment.

Procrastination and Stress

How does procrastination impact student stress levels?

Ask participants about how frequently they procrastinate on their homework and then have them complete an assessment looking at their current stress levels.

Caffeine and Cognition

How does caffeine impact performance on a Stroop test?

In the Stroop test , participants are asked to tell the color of a word, rather than just reading the word. Have a control group consume no caffeine and then complete a Stroop test, and then have an experimental group consume caffeine before completing the same test. Compare results.

Color and Memory

Does the color of text have any impact on memory?

Randomly assign participants to two groups. Have one group memorize words written in black ink for two minutes. Have the second group memorize the same words for the same amount of time, but instead written in red ink. Compare the results.

Weight Bias

How does weight bias influence how people are judged by others?

Find pictures of models in a magazine who look similar, including similar hair and clothing, but who differ in terms of weight. Have participants look at the two models and then ask them to identify which one they think is smarter, wealthier, kinder, and healthier.

Assess how each model was rated and how weight bias may have influenced how they were described by participants.

Music and Exercise

Does music have an effect on how hard people work out?

Have people listen to different styles of music while jogging on a treadmill and measure their walking speed, heart rate, and workout length.

The Halo Effect

How does the Halo Effect influence how people see others?

Show participants pictures of people and ask them to rate the photos in terms of how attractive, kind, intelligent, helpful, and successful the people in the images are.

How does the attractiveness of the person in the photo correlate to how participants rate other qualities? Are attractive people more likely to be perceived as kind, funny, and intelligent?

Eyewitness Testimony

How reliable is eyewitness testimony?

Have participants view video footage of a car crash. Ask some participants to describe how fast the cars were going when they “hit into” each other. Ask other participants to describe how fast the cars were going when they “smashed into” each other.

Give the participants a memory test a few days later and ask them to recall if they saw any broken glass at the accident scene. Compare to see if those in the “smashed into” condition were more likely to report seeing broken glass than those in the “hit into” group.

The experiment is a good illustration of how easily false memories can be triggered.

Simple Psychology Experiment Ideas

If you are looking for a relatively simple psychology experiment idea, here are a few options you might consider.

The Stroop Effect

This classic experiment involves presenting participants with words printed in different colors and asking them to name the color of the ink rather than read the word. Students can manipulate the congruency of the word and the color to test the Stroop effect.

Memory Recall

Students can design a simple experiment to test memory recall by presenting participants with a list of items to remember and then asking them to recall the items after a delay. Students can manipulate the length of the delay or the type of encoding strategy used to see the effect on recall.

Social Conformity

Students can test social conformity by presenting participants with a simple task and manipulating the responses of confederates to see if the participant conforms to the group response.

Selective Attention

Students can design an experiment to test selective attention by presenting participants with a video or audio stimulus and manipulating the presence or absence of a distracting stimulus to see the effect on attention.

Implicit Bias

Students can test implicit bias by presenting participants with a series of words or images and measuring their response time to categorize the stimuli into different categories.

The Primacy/Recency Effect

Students can test the primacy /recency effect by presenting participants with a list of items to remember and manipulating the order of the items to see the effect on recall.

Sleep Deprivation

Students can test the effect of sleep deprivation on cognitive performance by comparing the performance of participants who have had a full night’s sleep to those who have been deprived of sleep.

These are just a few examples of simple psychology experiment ideas for students. The specific experiment will depend on the research question and resources available.

Elements of a Good Psychology Experiment

Finding psychology experiment ideas is not necessarily difficult, but finding a good experimental or study topic that is right for your needs can be a little tough. You need to find something that meets the guidelines and, perhaps most importantly, is approved by your instructor.

Requirements may vary, but you need to ensure that your experiment, study, or survey is:

  • Easy to set up and carry out
  • Easy to find participants willing to take part
  • Free of any ethical concerns

In some cases, you may need to present your idea to your school’s institutional review board before you begin to obtain permission to work with human participants.

Consider Your Own Interests

At some point in your life, you have likely pondered why people behave in certain ways. Or wondered why certain things seem to always happen. Your own interests can be a rich source of ideas for your psychology experiments.

As you are trying to come up with a topic or hypothesis, try focusing on the subjects that fascinate you the most. If you have a particular interest in a topic, look for ideas that answer questions about the topic that you and others may have. Examples of topics you might choose to explore include:

  • Development
  • Personality
  • Social behavior

This can be a fun opportunity to investigate something that appeals to your interests.

Read About Classic Experiments

Sometimes reviewing classic psychological experiments that have been done in the past can give you great ideas for your own psychology experiments. For example, the false memory experiment above is inspired by the classic memory study conducted by Elizabeth Loftus.

Textbooks can be a great place to start looking for topics, but you might want to expand your search to research journals. When you find a study that sparks your interest, read through the discussion section. Researchers will often indicate ideas for future directions that research could take.

Ask Your Instructor

Your professor or instructor is often the best person to consult for advice right from the start.

In most cases, you will probably receive fairly detailed instructions about your assignment. This may include information about the sort of topic you can choose or perhaps the type of experiment or study on which you should focus.

If your instructor does not assign a specific subject area to explore, it is still a great idea to talk about your ideas and get feedback before you get too invested in your topic idea. You will need your teacher’s permission to proceed with your experiment anyway, so now is a great time to open a dialogue and get some good critical feedback.

Experiments vs. Other Types of Research

One thing to note, many of the ideas found here are actually examples of surveys or correlational studies .

For something to qualify as a tru e experiment, there must be manipulation of an independent variable .

For many students, conducting an actual experiment may be outside the scope of their project or may not be permitted by their instructor, school, or institutional review board.

If your assignment or project requires you to conduct a true experiment that involves controlling and manipulating an independent variable, you will need to take care to choose a topic that will work within the guidelines of your assignment.

Types of Psychology Experiments

There are many different types of psychology experiments that students could perform. Examples of psychological research methods you might use include:

Correlational Study

This type of study examines the relationship between two variables. Students could collect data on two variables of interest, such as stress and academic performance, and see if there is a correlation between the two.

Experimental Study

In an experimental study, students manipulate one variable and observe the effect on another variable. For example, students could manipulate the type of music participants listen to and observe its effect on their mood.

Observational Study

Observational studies involve observing behavior in a natural setting . Students could observe how people interact in a public space and analyze the patterns they see.

Survey Study

Students could design a survey to collect data on a specific topic, such as attitudes toward social media, and analyze the results.

A case study involves in-depth analysis of a single individual or group. Students could conduct a case study of a person with a particular disorder, such as anxiety or depression, and examine their experiences and treatment options.

Quasi-Experimental Study

Quasi-experimental studies are similar to experimental studies, but participants are not randomly assigned to groups. Students could investigate the effects of a treatment or intervention on a particular group, such as a classroom of students who receive a new teaching method.

Longitudinal Study

Longitudinal studies involve following participants over an extended period of time. Students could conduct a longitudinal study on the development of language skills in children or the effects of aging on cognitive abilities.

These are just a few examples of the many different types of psychology experiments that students could perform. The specific type of experiment will depend on the research question and the resources available.

Steps for Doing a Psychology Experiment

When conducting a psychology experiment, students should follow several important steps. Here is a general outline of the process:

Define the Research Question

Before conducting an experiment, students should define the research question they are trying to answer. This will help them to focus their study and determine the variables they need to manipulate and measure.

Develop a Hypothesis

Based on the research question, students should develop a hypothesis that predicts the experiment’s outcome. The hypothesis should be testable and measurable.

Select Participants

Students should select participants who meet the criteria for the study. Participants should be informed about the study and give informed consent to participate.

Design the Experiment

Students should design the experiment to test their hypothesis. This includes selecting the appropriate variables, creating a plan for manipulating and measuring them, and determining the appropriate control conditions.

Collect Data

Once the experiment is designed, students should collect data by following the procedures they have developed. They should record all data accurately and completely.

Analyze the Data

After collecting the data, students should analyze it to determine if their hypothesis was supported or not. They can use statistical analyses to determine if there are significant differences between groups or if there are correlations between variables.

Interpret the Results

Based on the analysis, students should interpret the results and draw conclusions about their hypothesis. They should consider the study’s limitations and their findings’ implications.

Report the Results

Finally, students should report the results of their study. This may include writing a research paper or presenting their findings in a poster or oral presentation.

11+ Psychology Experiment Ideas (Goals + Methods)

practical psychology logo

Have you ever wondered why some days you remember things easily, while on others you keep forgetting? Or why certain songs make you super happy and others just…meh?

Our minds are like big, mysterious puzzles, and every day we're finding new pieces to fit. One of the coolest ways to explore our brains and the way they work is through psychology experiments.

A psychology experiment is a special kind of test or activity researchers use to learn more about how our minds work and why we behave the way we do.

It's like a detective game where scientists ask questions and try out different clues to find answers about our feelings, thoughts, and actions. These experiments aren't just for scientists in white coats but can be fun activities we all try to discover more about ourselves and others.

Some of these experiments have become so famous, they’re like the celebrities of the science world! Like the Marshmallow Test, where kids had to wait to eat a yummy marshmallow, or Pavlov's Dogs, where dogs learned to drool just hearing a bell.

Let's look at a few examples of psychology experiments you can do at home.

What Are Some Classic Experiments?

Imagine a time when the mysteries of the mind were being uncovered in groundbreaking ways. During these moments, a few experiments became legendary, capturing the world's attention with their intriguing results.

testing tubes

The Marshmallow Test

One of the most talked-about experiments of the 20th century was the Marshmallow Test , conducted by Walter Mischel in the late 1960s at Stanford University.

The goal was simple but profound: to understand a child's ability to delay gratification and exercise self-control.

Children were placed in a room with a marshmallow and given a choice: eat the marshmallow now or wait 15 minutes and receive two as a reward. Many kids struggled with the wait, some devouring the treat immediately, while others demonstrated remarkable patience.

But the experiment didn’t end there. Years later, Mischel discovered something astonishing. The children who had waited for the second marshmallow were generally more successful in several areas of life, from school achievements to job satisfaction!

While this experiment highlighted the importance of teaching patience and self-control from a young age, it wasn't without its criticisms. Some argued that a child's background, upbringing, or immediate surroundings might play a significant role in their choices.

Moreover, there were concerns about the ethics of judging a child's potential success based on a brief interaction with a marshmallow.

Pavlov's Dogs

Traveling further back in time and over to Russia, another classic experiment took the world by storm. Ivan Pavlov , in the early 1900s, wasn't initially studying learning or behavior. He was exploring the digestive systems of dogs.

But during his research, Pavlov stumbled upon a fascinating discovery. He noticed that by ringing a bell every time he fed his dogs, they eventually began to associate the bell's sound with mealtime. So much so, that merely ringing the bell, even without presenting food, made the dogs drool in anticipation!

This reaction demonstrated the concept of "conditioning" - where behaviors can be learned by linking two unrelated stimuli. Pavlov's work revolutionized the world's understanding of learning and had ripple effects in various areas like animal training and therapy techniques.

Pavlov came up with the term classical conditioning , which is still used today. Other psychologists have developed more nuanced types of conditioning that help us understand how people learn to perform different behaviours.

Classical conditioning is the process by which a neutral stimulus becomes associated with a meaningful stimulus , leading to the same response. In Pavlov's case, the neutral stimulus (bell) became associated with the meaningful stimulus (food), leading the dogs to salivate just by hearing the bell.

Modern thinkers often critique Pavlov's methods from an ethical standpoint. The dogs, crucial to his discovery, may not have been treated with today's standards of care and respect in research.

Both these experiments, while enlightening, also underline the importance of conducting research with empathy and consideration, especially when it involves living beings.

What is Ethical Experimentation?

The tales of Pavlov's bells and Mischel's marshmallows offer us not just insights into the human mind and behavior but also raise a significant question: At what cost do these discoveries come?

Ethical experimentation isn't just a fancy term; it's the backbone of good science. When we talk about ethics, we're referring to the moral principles that guide a researcher's decisions and actions. But why does it matter so much in the realm of psychological experimentation?

An example of an experiment that had major ethical issues is an experiment called the Monster Study . This study was conducted in 1936 and was interested in why children develop a stutter.

The major issue with it is that the psychologists treated some of the children poorly over a period of five months, telling them things like “You must try to stop yourself immediately. Don’t ever speak unless you can do it right.”

You can imagine how that made the children feel!

This study helped create guidelines for ethical treatment in experiments. The guidelines include:

Respect for Individuals: Whether it's a dog in Pavlov's lab or a child in Mischel's study room, every participant—human or animal—deserves respect. They should never be subjected to harm or undue stress. For humans, informed consent (knowing what they're signing up for) is a must. This means that if a child is participating, they, along with their guardians, should understand what the experiment entails and agree to it without being pressured.

Honesty is the Best Policy: Researchers have a responsibility to be truthful. This means not only being honest with participants about the study but also reporting findings truthfully, even if the results aren't what they hoped for. There can be exceptions if an experiment will only succeed if the participants aren't fully aware, but it has to be approved by an ethics committee .

Safety First: No discovery, no matter how groundbreaking, is worth harming a participant. The well-being and mental, emotional, and physical safety of participants is paramount. Experiments should be designed to minimize risks and discomfort.

Considering the Long-Term: Some experiments might have effects that aren't immediately obvious. For example, while a child might seem fine after participating in an experiment, they could feel stressed or anxious later on. Ethical researchers consider and plan for these possibilities, offering support and follow-up if needed.

The Rights of Animals: Just because animals can't voice their rights doesn't mean they don't have any. They should be treated with care, dignity, and respect. This means providing them with appropriate living conditions, not subjecting them to undue harm, and considering alternatives to animal testing when possible.

While the world of psychological experiments offers fascinating insights into behavior and the mind, it's essential to tread with care and compassion. The golden rule? Treat every participant, human or animal, as you'd wish to be treated. After all, the true mark of a groundbreaking experiment isn't just its findings but the ethical integrity with which it's conducted.

So, even if you're experimenting at home, please keep in mind the impact your experiments could have on the people and beings around you!

Let's get into some ideas for experiments.

1) Testing Conformity

Our primary aim with this experiment is to explore the intriguing world of social influences, specifically focusing on how much sway a group has over an individual's decisions. This social influence is called groupthink .

Humans, as social creatures, often find solace in numbers, seeking the approval and acceptance of those around them. But how deep does this need run? Does the desire to "fit in" overpower our trust in our own judgments?

This experiment not only provides insights into these questions but also touches upon the broader themes of peer pressure, societal norms, and individuality. Understanding this could shed light on various real-world situations, from why fashion trends catch on to more critical scenarios like how misinformation can spread.

Method: This idea is inspired by the classic Asch Conformity Experiments . Here's a simple way to try it:

  • Assemble a group of people (about 7-8). Only one person will be the real participant; the others will be in on the experiment.
  • Show the group a picture of three lines of different lengths and another line labeled "Test Line."
  • Ask each person to say out loud which of the three lines matches the length of the "Test Line."
  • Unknown to the real participant, the other members will intentionally choose the wrong line. This is to see if the participant goes along with the group's incorrect choice, even if they can see it's wrong.

Real-World Impacts of Groupthink

Groupthink is more than just a science term; we see it in our daily lives:

Decisions at Work or School: Imagine being in a group where everyone wants to do one thing, even if it's not the best idea. People might not speak up because they're worried about standing out or being the only one with a different opinion.

Wrong Information: Ever heard a rumor that turned out to be untrue? Sometimes, if many people believe and share something, others might believe it too, even if it's not correct. This happens a lot on the internet.

Peer Pressure: Sometimes, friends might all want to do something that's not safe or right. People might join in just because they don't want to feel left out.

Missing Out on New Ideas: When everyone thinks the same way and agrees all the time, cool new ideas might never get heard. It's like always coloring with the same crayon and missing out on all the other bright colors!

2) Testing Color and Mood

colorful room

We all have favorite colors, right? But did you ever wonder if colors can make you feel a certain way? Color psychology is the study of how colors can influence our feelings and actions.

For instance, does blue always calm us down? Does red make us feel excited or even a bit angry? By exploring this, we can learn how colors play a role in our daily lives, from the clothes we wear to the color of our bedroom walls.

  • Find a quiet room and set up different colored lights or large sheets of colored paper: blue, red, yellow, and green.
  • Invite some friends over and let each person spend a few minutes under each colored light or in front of each colored paper.
  • After each color, ask your friends to write down or talk about how they feel. Are they relaxed? Energized? Happy? Sad?

Researchers have always been curious about this. Some studies have shown that colors like blue and green can make people feel calm, while colors like red might make them feel more alert or even hungry!

Real-World Impacts of Color Psychology

Ever noticed how different places use colors?

Hospitals and doctors' clinics often use soft blues and greens. This might be to help patients feel more relaxed and calm.

Many fast food restaurants use bright reds and yellows. These colors might make us feel hungry or want to eat quickly and leave.

Classrooms might use a mix of colors to help students feel both calm and energized.

3) Testing Music and Brainpower

Think about your favorite song. Do you feel smarter or more focused when you listen to it? This experiment seeks to understand the relationship between music and our brain's ability to remember things. Some people believe that certain types of music, like classical tunes, can help us study or work better. Let's find out if it's true!

  • Prepare a list of 10-15 things to remember, like a grocery list or names of places.
  • Invite some friends over. First, let them try to memorize the list in a quiet room.
  • After a short break, play some music (try different types like pop, classical, or even nature sounds) and ask them to memorize the list again.
  • Compare the results. Was there a difference in how much they remembered with and without music?

The " Mozart Effect " is a popular idea. Some studies in the past suggested that listening to Mozart's music might make people smarter, at least for a little while. But other researchers think the effect might not be specific to Mozart; it could be that any music we enjoy boosts our mood and helps our brain work better.

Real-World Impacts of Music and Memory

Think about how we use music:

  • Study Sessions: Many students listen to music while studying, believing it helps them concentrate better.
  • Workout Playlists: Gyms play energetic music to keep people motivated and help them push through tough workouts.
  • Meditation and Relaxation: Calm, soothing sounds are often used to help people relax or meditate.

4) Testing Dreams and Food

Ever had a really wild dream and wondered where it came from? Some say that eating certain foods before bedtime can make our dreams more vivid or even a bit strange.

This experiment is all about diving into the dreamy world of sleep to see if what we eat can really change our nighttime adventures. Can a piece of chocolate or a slice of cheese transport us to a land of wacky dreams? Let's find out!

  • Ask a group of friends to keep a "dream diary" for a week. Every morning, they should write down what they remember about their dreams.
  • For the next week, ask them to eat a small snack before bed, like cheese, chocolate, or even spicy foods.
  • They should continue writing in their "dream diary" every morning.
  • At the end of the two weeks, compare the dream notes. Do the dreams seem different during the snack week?

The link between food and dreams isn't super clear, but some people have shared personal stories. For example, some say that spicy food can lead to bizarre dreams. Scientists aren't completely sure why, but it could be related to how food affects our body temperature or brain activity during sleep.

A cool idea related to this experiment is that of vivid dreams , which are very clear, detailed, and easy to remember dreams. Some people are even able to control their vivid dreams, or say that they feel as real as daily, waking life !

Real-World Impacts of Food and Dreams

Our discoveries might shed light on:

  • Bedtime Routines: Knowing which foods might affect our dreams can help us choose better snacks before bedtime, especially if we want calmer sleep.
  • Understanding Our Brain: Dreams can be mysterious, but studying them can give us clues about how our brains work at night.
  • Cultural Beliefs: Many cultures have myths or stories about foods and dreams. Our findings might add a fun twist to these age-old tales!

5) Testing Mirrors and Self-image

Stand in front of a mirror. How do you feel? Proud? Shy? Curious? Mirrors reflect more than just our appearance; they might influence how we think about ourselves.

This experiment delves into the mystery of self-perception. Do we feel more confident when we see our reflection? Or do we become more self-conscious? Let's take a closer look.

  • Set up two rooms: one with mirrors on all walls and another with no mirrors at all.
  • Invite friends over and ask them to spend some time in each room doing normal activities, like reading or talking.
  • After their time in both rooms, ask them questions like: "Did you think about how you looked more in one room? Did you feel more confident or shy?"
  • Compare the responses to see if the presence of mirrors changes how they feel about themselves.

Studies have shown that when people are in rooms with mirrors, they can become more aware of themselves. Some might stand straighter, fix their hair, or even change how they behave. The mirror acts like an audience, making us more conscious of our actions.

Real-World Impacts of Mirrors and Self-perception

Mirrors aren't just for checking our hair. Ever wonder why clothing stores have so many mirrors? They might help shoppers visualize themselves in new outfits, encouraging them to buy.

Mirrors in gyms can motivate people to work out with correct form and posture. They also help us see progress in real-time!

And sometimes, looking in a mirror can be a reminder to take care of ourselves, both inside and out.

But remember, what we look like isn't as important as how we act in the world or how healthy we are. Some people claim that having too many mirrors around can actually make us more self conscious and distract us from the good parts of ourselves.

Some studies are showing that mirrors can actually increase self-compassion , amongst other things. As any tool, it seems like mirrors can be both good and bad, depending on how we use them!

6) Testing Plants and Talking

potted plants

Have you ever seen someone talking to their plants? It might sound silly, but some people believe that plants can "feel" our vibes and that talking to them might even help them grow better.

In this experiment, we'll explore whether plants can indeed react to our voices and if they might grow taller, faster, or healthier when we chat with them.

  • Get three similar plants, placing each one in a separate room.
  • Talk to the first plant, saying positive things like "You're doing great!" or singing to it.
  • Say negative things to the second plant, like "You're not growing fast enough!"
  • Don't talk to the third plant at all; let it be your "silent" control group .
  • Water all plants equally and make sure they all get the same amount of light.
  • At the end of the month, measure the growth of each plant and note any differences in their health or size.

The idea isn't brand new. Some experiments from the past suggest plants might respond to sounds or vibrations. Some growers play music for their crops, thinking it helps them flourish.

Even if talking to our plants doesn't have an impact on their growth, it can make us feel better! Sometimes, if we are lonely, talking to our plants can help us feel less alone. Remember, they are living too!

Real-World Impacts of Talking to Plants

If plants do react to our voices, gardeners and farmers might adopt new techniques, like playing music in greenhouses or regularly talking to plants.

Taking care of plants and talking to them could become a recommended activity for reducing stress and boosting mood.

And if plants react to sound, it gives us a whole new perspective on how connected all living things might be .

7) Testing Virtual Reality and Senses

Virtual reality (VR) seems like magic, doesn't it? You put on a headset and suddenly, you're in a different world! But how does this "new world" affect our senses? This experiment wants to find out how our brains react to VR compared to the real world. Do we feel, see, or hear things differently? Let's get to the bottom of this digital mystery!

  • You'll need a VR headset and a game or experience that can be replicated in real life (like walking through a forest). If you don't have a headset yourself, there are virtual reality arcades now!
  • Invite friends to first experience the scenario in VR.
  • Afterwards, replicate the experience in the real world, like taking a walk in an actual forest.
  • Ask them questions about both experiences: Did one seem more real than the other? Which sounds were more clear? Which colors were brighter? Did they feel different emotions?

As VR becomes more popular, scientists have been curious about its effects. Some studies show that our brains can sometimes struggle to tell the difference between VR and reality. That's why some people might feel like they're really "falling" in a VR game even though they're standing still.

Real-World Impacts of VR on Our Senses

Schools might use VR to teach lessons, like taking students on a virtual trip to ancient Egypt. Understanding how our senses react in VR can also help game designers create even more exciting and realistic games.

Doctors could use VR to help patients overcome fears or to provide relaxation exercises. This is actually already a method therapists can use for helping patients who have serious phobias. This is called exposure therapy , which basically means slowly exposing someone (or yourself) to the thing you fear, starting from very far away to becoming closer.

For instance, if someone is afraid of snakes. You might show them images of snakes first. Once they are comfortable with the picture, they can know there is one in the next room. Once they are okay with that, they might use a VR headset to see the snake in the same room with them, though of course there is not an actual snake there.

8) Testing Sleep and Learning

We all know that feeling of trying to study or work when we're super tired. Our brains feel foggy, and it's hard to remember stuff. But how exactly does sleep (or lack of it) influence our ability to learn and remember things?

With this experiment, we'll uncover the mysteries of sleep and see how it can be our secret weapon for better learning.

  • Split participants into two groups.
  • Ask both groups to study the same material in the evening.
  • One group goes to bed early, while the other stays up late.
  • The next morning, give both groups a quiz on what they studied.
  • Compare the results to see which group remembered more.

Sleep and its relation to learning have been explored a lot. Scientists believe that during sleep, especially deep sleep, our brains sort and store new information. This is why sometimes, after a good night's rest, we might understand something better or remember more.

Real-World Impacts of Sleep and Learning

Understanding the power of sleep can help:

  • Students: If they know the importance of sleep, students might plan better, mixing study sessions with rest, especially before big exams.
  • Workplaces: Employers might consider more flexible hours, understanding that well-rested employees learn faster and make fewer mistakes.
  • Health: Regularly missing out on sleep can have other bad effects on our health. So, promoting good sleep is about more than just better learning.

9) Testing Social Media and Mood

Have you ever felt different after spending time on social media? Maybe happy after seeing a friend's fun photos, or a bit sad after reading someone's tough news.

Social media is a big part of our lives, but how does it really affect our mood? This experiment aims to shine a light on the emotional roller-coaster of likes, shares, and comments.

  • Ask participants to note down how they're feeling - are they happy, sad, excited, or bored?
  • Have them spend a set amount of time (like 30 minutes) on their favorite social media platforms.
  • After the session, ask them again about their mood. Did it change? Why?
  • Discuss what they saw or read that made them feel that way.

Previous research has shown mixed results. Some studies suggest that seeing positive posts can make us feel good, while others say that too much time on social media can make us feel lonely or left out.

Real-World Impacts of Social Media on Mood

Understanding the emotional impact of social media can help users understand their feelings and take breaks if needed. Knowing is half the battle! Additionally, teachers and parents can guide young users on healthy social media habits, like limiting time or following positive accounts.

And if it's shown that social media does impact mood, social media companies can design friendlier, less stressful user experiences.

But even if the social media companies don't change things, we can still change our social media habits to make ourselves feel better.

10) Testing Handwriting or Typing

Think about the last time you took notes. Did you grab a pen and paper or did you type them out on a computer or tablet?

Both ways are popular, but there's a big question: which method helps us remember and understand better? In this experiment, we'll find out if the classic art of handwriting has an edge over speedy typing.

  • Divide participants into two groups.
  • Present a short lesson or story to both groups.
  • One group will take notes by hand, while the other will type them out.
  • After some time, quiz both groups on the content of the lesson or story.
  • Compare the results to see which note-taking method led to better recall and understanding.

Studies have shown some interesting results. While typing can be faster and allows for more notes, handwriting might boost memory and comprehension because it engages the brain differently, making us process the information as we write.

Importantly, each person might find one or the other works better for them. This could be useful in understanding our learning habits and what instructional style would be best for us.

Real-World Impacts of Handwriting vs. Typing

Knowing the pros and cons of each method can:

  • Boost Study Habits: Students can pick the method that helps them learn best, especially during important study sessions or lectures.
  • Work Efficiency: In jobs where information retention is crucial, understanding the best method can increase efficiency and accuracy.
  • Tech Design: If we find out more about how handwriting benefits us, tech companies might design gadgets that mimic the feel of writing while combining the advantages of digital tools.

11) Testing Money and Happiness

game board with money

We often hear the saying, "Money can't buy happiness," but is that really true? Many dream of winning the lottery or getting a big raise, believing it would solve all problems.

In this experiment, we dig deep to see if there's a real connection between wealth and well-being.

  • Survey a range of participants, from those who earn a little to those who earn a lot, about their overall happiness. You can keep it to your friends and family, but that might not be as accurate as surveying a wider group of people.
  • Ask them to rank things that bring them joy and note if they believe more money would boost their happiness. You could try different methods, one where you include some things that they have to rank, such as gardening, spending time with friends, reading books, learning, etc. Or you could just leave a blank list that they can fill in with their own ideas.
  • Study the data to find patterns or trends about income and happiness.

Some studies have found money can boost happiness, especially when it helps people out of tough financial spots. But after reaching a certain income, extra dollars usually do not add much extra joy.

In fact, psychologists just realized that once people have an income that can comfortably support their needs (and some of their wants), they stop getting happier with more . That number is roughly $75,000, but of course that depends on the cost of living and how many members are in the family.

Real-World Impacts of Money and Happiness

If we can understand the link between money and joy, it might help folks choose jobs they love over jobs that just pay well. And instead of buying things, people might spend on experiences, like trips or classes, that make lasting memories.

Most importantly, we all might spend more time on hobbies, friends, and family, knowing they're big parts of what makes life great.

Some people are hoping that with Artificial Intelligence being able to do a lot of the less well-paying jobs, people might be able to do work they enjoy more, all while making more money and having more time to do the things that make them happy.

12) Testing Temperature and Productivity

Have you ever noticed how a cold classroom or office makes it harder to focus? Or how on hot days, all you want to do is relax? In this experiment, we're going to find out if the temperature around us really does change how well we work.

  • Find a group of participants and a room where you can change the temperature.
  • Set the room to a chilly temperature and give the participants a set of tasks to do.
  • Measure how well and quickly they do these tasks.
  • The next day, make the room comfortably warm and have them do similar tasks.
  • Compare the results to see if the warmer or cooler temperature made them work better.

Some studies have shown that people can work better when they're in a room that feels just right, not too cold or hot. Being too chilly can make fingers slow, and being too warm can make minds wander.

What temperature is "just right"? It won't be the same for everyone, but most people find it's between 70-73 degrees Fahrenheit (21-23 Celsius).

Real-World Implications of Temperature and Productivity

If we can learn more about how temperature affects our work, teachers might set classroom temperatures to help students focus and learn better, offices might adjust temperatures to get the best work out of their teams, and at home, we might find the best temperature for doing homework or chores quickly and well.

Interestingly, temperature also has an impact on our sleep quality. Most people find slightly cooler rooms to be better for good sleep. While the daytime temperature between 70-73F is good for productivity, a nighttime temperature around 65F (18C) is ideal for most people's sleep.

Psychology is like a treasure hunt, where the prize is understanding ourselves better. With every experiment, we learn a little more about why we think, feel, and act the way we do. Some of these experiments might seem simple, like seeing if colors change our mood or if being warm helps us work better. But even the simple questions can have big answers that help us in everyday life.

Remember, while doing experiments is fun, it's also important to always be kind and think about how others feel. We should never make someone uncomfortable just for a test. Instead, let's use these experiments to learn and grow, helping to make the world a brighter, more understanding place for everyone.

With thousands of possible projects, it can be difficult to narrow down something that’s a good fit for every student. Try these tips to help them find the right science fair project ideas.

Match Your Project to Your Interests

This seems obvious, but it’s really helpful for kids who feel overwhelmed by all the choices. It’s also a good way to get reluctant learners more excited about science fair projects. Encourage students to think about what they love to do in their spare time. How can they turn that into a project?

For instance, kids who love sports might explore the most effective stretches for warming up, or methods for throwing a football farther and more accurately. Music lovers can learn how sound waves work, or discover the link between music and emotions. It’s all about starting with something you love.

Challenge Yourself, But Keep It Realistic

Science fair projects need to be something kids can complete by themselves or with adults in support roles only. If a student picks something that’s way beyond their skill level, chances are the parents will wind up doing most of it. That being said, the point of the project is to learn and grow. Aim to learn something new, whether it’s knowledge or skills, by setting measurable goals.

If You Want To Win, Be Innovative

For science fair contests with prizes, the more creative you can be, the better. Projects that address real-world problems with new and interesting solutions often catch the judges’ eye. Be sure to be thorough in your research, and be ready to answer questions about your methods and results. Scientists love asking questions!

DARPA’s Secret New X-Plane Looks Like It’ll Blow Some Minds

The XRQ-73 will take to the skies this year.

a shark in the desert

  • DARPA has initiated an effort to build a new, stealthy spy plane.
  • Unlike other aircraft, this X-plane will feature a hybrid electric propulsion system.
  • The XRQ-73 will be much quieter than traditional aircraft, making it harder to detect over enemy territory.

Hybrid Spy Plane

b 2 stealth bomber

The Defense Advanced Research Projects Agency, or DARPA , announced the new plane earlier this week via its website. The plane is designated XRQ-73: X for experimental plane, R for reconnaissance, and Q for unmanned. It would be the 73rd official X-plane developed by the Department of Defense—a long line of famed aircraft that started in 1946, with the Bell X-1 supersonic jet plane .

The plane’s designation gives away its purpose: an unmanned spy plane. The SHEPHARD name is an acronym—Series Hybrid Electric Propulsion AiRcraft Demonstration—and explains what will make the machine special. It will be the first known military aircraft to will do away with jet engines entirely, relying on electricity for propulsion .

According to DARPA , the XRQ-73 will be an unmanned aircraft designed to collect intelligence. Concept art depicts a flying wing design (like the B-21 Raider stealth bomber), the lack of a fuselage, vertical stabilizers, and a cockpit. The drone will be several orders of magnitude smaller than a bomber, however—DARPA says it is a Group 3 drone, a size class that tops out of 1,320 pounds. XRQ-73 will weight 1,250 pounds. Like the B-21 Raider, the XRQ-73 is also being built by Northrop Gruman. First flight is scheduled for sometime this year.

Electric Flight

On a regular jet aircraft , gas turbine engines suck in and pressurize air, then burn oxygen and jet fuel in a combustion chamber. The engine then pushes the gasses created by the process through the rear of the engine, creating the thrust that propels the aircraft forward.

In a hybrid electric propulsion aircraft, engines burn jet fuel to create electrical power. The power is then used to turn fans that create thrust. A hybrid propulsion aircraft can briefly rely on batteries, resulting in a quieter aircraft—a major quality of life improvement for people living near airports. It can use both direct electric power and battery power to temporarily increase power, such as during takeoffs. Engineers have been working on commercial hybrid electric aircraft for years, but a useful, fully operational craft has been elusive thus far.

Avoiding the “Flying Lawnmower”

iranian shahed drones

Smaller, short range flying drones like quadcopters and hexacopters are typically powered by batteries. As drones grow larger, they are expected to have longer ranges and greater payloads, and an internal combustion engine like a prop-driven engine or gas turbine is considered mandatory.

All of that additional power from burning fuel has a price: internal combustion engines are loud . The Shahed-136 —a prop-driven kamikaze drone designed by Iran and used by Russia in its war in Ukraine—makes so much noise that it is known as the “flying washing machine.” Ukrainian air defenders can usually hear the Shahed before they can see it, giving them time to man their anti-air defenses and scan the skies.

American drones are no exception. The U.S. Army’s RQ-7B Shadow is similarly noisy, producing a sound that resembles one continuous, unending fart. Like the XRQ-73, the RQ-7B is classified by the Pentagon as a Group 3 class drone—a class of drones that typically fly at a maximum altitude of 18,000 feet. A RQ-7B engine produces up to 99 decibels of sound , which at 18,000 feet would be reduced to 13 decibels . That’s the noise equivalent of a human being breathing , meaning that hearing a RQ-7 at three miles up is certainly possible.

Unlike civilian hybrid electric aircraft, military aircraft would use electric power differently. A plane like the XQR-73 would take off and land with the engine providing electrical power to the fans. As it nears enemy territory, the aircraft would switch off the gas turbine and power the fans from batteries . The drone’s engine noise disappears, and the plane is suddenly flying silent.

Son of Great Horned Owl

nature

XQR-73 is a direct descendant of Great Horned Owl (GHO)—another project to develop a quiet unmanned aerial vehicle. GHO was a project of the Intelligence Advanced Research Projects Activity (IARPA), DARPA’s equivalent in the intelligence community. The name is a reference to the ability of owls to fly silently, undetected by their prey.

It’s not clear whatever happened to Great Horned Owl. A 2011 PowerPoint presentation outlines the same key objectives of the XQR-73 program, so it’s possible that GHO was eventually deemed technically unachiveable at the time. The two aircraft programs rely on battery technology to succeed—a field that has seen remarkable progress in the last 13 years. So, perhaps DARPA thinks the tech has advanced to a point where silently flying a 1,250 pound drone is possible.

Great Horned Owl was also a Northrop Grumman Project , so some of the design will likely carry over to the XQR-73. One area where the two planes differ is the placement of the fans—GHO features four fans mounted above the aircraft, while the XQR-73 buries them inside the body of the aircraft. Burying the fans eliminates their radar signature, making the aircraft harder to detect.

Hybrid electric aircraft have the potential to revolutionize the aviation industry. A successful XQR-73 will be a groundbreaking aircraft, ushering in an era of quieter flight. Good news for people living in the flight path of airports , and bad news for America’s adversaries.

Regulatory Science Framework

Primary Charge : I. Modernize development and evaluation of FDA-regulated products: J. Methods to Assess Real-World Data to serve as Real-World Evidence Secondary Charge : I. Modernize development and evaluation of FDA-regulated products: E. Clinical Outcome Assessment

Regulatory Science Challenge

Wearables such as smart watches that track your movement or heartbeat are used frequently in research to track patient health. These devices generate a large amount of data, and new types of statistical methods are needed to properly analyze them and address challenges such as when patients do not wear the device. This collaboration will help create standards for handling non-wear periods that can be used to advance medical product development and improve patient health.

Project Description and Goals

The goal of this project is to improve understanding of data from wearable devices. To that end, investigators will

  • Develop an open-source tool to help simulate patient data from wearables including non-wear periods using databases from completed clinical trials
  • Create and test strategies for handling non-wear periods
  • Establish open source code for recommended strategies

Overall, advancement of science will help take data from patient wearables and translate them into evidence that can be used to get better treatments for all patients.

Anticipated Outcomes/Impact

The anticipated outcomes from this CERSI project include the following:

  • Development of an open-source simulation tool (R package) to help simulate patient data from wearables including non-wear periods using databases from completed clinical trials.
  • Creation of methods for identifying and handling non-wear periods
  • Establishment of open-source code for the developed multiple imputation methods.
  • a paper describing the gaps in handling missing data for digital health device studies;
  • a paper to identify non-wear using ensemble methods; and
  • a paper to investigate various multiple imputation methods for handling missing data from digital health devices.

Research Outcomes/Results

Two hundred and twenty-three patients with a mean age of 65 years completed the survey. These patients preferred a higher chance of good biopsy outcomes, and a lower chance of erectile dysfunction caused by the treatment and urinary incontinence after treatment. The patients stated in the survey that they are willing to accept:

  • a 15.1%-point increase in erectile dysfunction caused by the treatment to achieve a 10%-point increase in a good biopsy outcome after HIFU ablation, and
  • an 8.5%-point increase in urinary incontinence for a 10%-point increase in a good biopsy.

Also, further analysis revealed that patients who thought their cancer was more aggressive were more willing to tolerate urinary incontinence. Younger men were willing to tolerate less erectile dysfunction risk than older men. Respondents with a greater than college level of education were less willing to tolerate erectile dysfunction or urinary incontinence.

Research Impacts

Incorporating patient preference information into decisions that FDA makes about regulating devices is one of the major goals of FDA’s Center for Devices and Radiological Health (CDRH). Study findings show that patients prefer specific outcomes related to prostate ablation therapies like HIFU. The study results may help inform the design and regulation of current and future prostate tissue ablation devices by providing information about outcomes that patients most desire.

How Science Went to the Dogs (and Cats)

Pets were once dismissed as trivial scientific subjects. Today, companion animal science is hot.

Emily Anthes, who has both a dog and a cat, has been writing about canine genetics since 2004.

  • June 30, 2024

This article is part of our Pets special section on scientists’ growing interest in our animal companions.

Every dog has its day, and July 14, 2004, belonged to a boxer named Tasha. On that date, the National Institutes of Health announced that the barrel-chested, generously jowled canine had become the first dog to have her complete genome sequenced. “And everything has kind of exploded since then,” said Elaine Ostrander, a canine genomics expert at the National Human Genome Research Institute, who was part of the research team.

In the 20 years since, geneticists have fallen hard for our canine companions, sequencing thousands upon thousands of dogs, including pedigreed purebreds, mysterious mutts, highly trained working dogs, free-ranging village dogs and even ancient canine remains.

Research on canine cognition and behavior has taken off, too. “Now dog posters are taking up half of an animal behavior conference,” said Monique Udell, who directs the human-animal interaction lab at Oregon State University. “And we’re starting to see cat research following that same trend.”

Just a few decades ago, many researchers considered pets to be deeply unserious subjects. (“I didn’t want to study dogs,” said Alexandra Horowitz, who has since become a prominent researcher in the field of canine cognition.) Today, companion animals are absolutely in vogue. Scientists around the world are peering deep into the bodies and minds of cats and dogs, hoping to learn more about how they wriggled their way into our lives, how they experience the world and how to keep them living in it longer. It’s a shift that some experts say is long overdue.

“We have a responsibility to deeply understand these animals if we’re going to live with them,” Dr. Udell said. “We also have this great potential to learn a lot about them and a lot about ourselves in the process.”

Pet projects

For geneticists, dogs and cats are both rich subjects , given their long, close history with humans and their susceptibility to many of the same diseases, from cancer to diabetes.
