Students of all ages enjoy watching this experiment , and it’s helpful to show them the ways that chemical reactions operate.

36. Coca-Cola Tooth Experiment 

This is a classic experiment that can help show students the effects of sugary drinks on their teeth. When your students are young and losing their baby teeth, ask them to bring in a tooth and show them the horrible effects in a jar! 

37. Small Tornado In A Bottle

Most of us performed this experiment when we were students, and it’s super fun to keep it going with your own students. Demonstrating centripetal force by creating a water vortex in a bottle is awesome! 

38. Make A Bag Leak-Proof

Another experiment that demonstrates polymers, you need a plastic bag, some water, a sharp pencil, and some patience – and you can show kids the seemingly impossible!

39. Make A Non-Newtonian Fluid 

There are substances out there that get firmer when pressure is applied to them, and these are known as non-Newtonian fluids. It’s really intriguing to see how fluids can behave in such ways, so your students are bound to get a kick out of this.

40. Demonstrate Capillaries

You can show kids how our capillaries function using items you can find pretty much everywhere. It’s super cool and colorful and you’re bound to excite everyone with this in the classroom.

41. Make Candy Rock 

Students, candy, and rocks – they go hand in hand! Your students will love to create their own candy rock and watch as the rock crystals grow.

42. Make The Super Bubble

You can show students how to make a better version of bubble mixture to create much larger bubbles, called superbubbles! 

43. Frozen Vegetable Oil Paintings

Here’s another classic experiment that most kids have conducted when they were in the classroom. It’s a fun way to show kids how some liquids behave when they are frozen, and as vegetable oil behaves differently – you can make awesome paintings! 

44. Make An Ice Magnifying Glass 

This experiment is pretty simple, but we like to add something more fun to it. Once you have made your ice magnifying glass, show your students how glass behaves underwater by designing a real magnifying glass (do not allow them to do this though).

Glass under water can be cut and sliced in much different ways than above the surface, so you can easily create your own glass designs to show your students in a safe way.

45. Can Eggs Float?

Finally, on our list, we have the experiment that has shown students for years how eggs can float on water if salt is added to the liquid. It’s a simple way to explain density, and it’s always a good idea to bring in the Dead Sea example.

The Dead Sea is so salty that people can simply float on its surface, but it’s also deadly because if you turn around – it’s difficult to get your head out of the salty water! 

Things To Remember

There are always things you should remember when it comes to these sorts of experiments. Some are much more obvious than others, but it’s always important to ensure we’re on the same wavelength. These include the following.

Safety 

Conduct a health and safety risk assessment before you carry out any experiment, and always be aware of any safety equipment you and your students may need to wear. Be sure to take reasonable care with all of your experiments (and best to do a trial run first!).

Reinforce Learning 

It’s all fine and good demonstrating the experiments, but you must ensure that you reinforce the student’s learning by asking questions at the end of the lesson. It’s also wise to set some theoretical homework based on their practical experiment. 

Do Your Research 

It’s of course critical that you know exactly what you are doing before you show your students, but it’s also as important to know your students. For example, if an experiment is more tailored for younger students, do not try it for older kids.  You may also like: 1st grade science project ideas .

The Bottom Line 

And that’s our comprehensive list of the easiest science experiments that you can show students in the classroom, at home, or out in the field! We hope you have enjoyed our guide and you’ve found some amazing new experiments for your students! Good luck.

Top tip: Teach your students about the most famous inventors while they work on their own science experiments.

70 Best High School Science Fair Projects in Every Subject

Fire up the Bunsen burners!

The cool thing about high school science fair projects is that kids are old enough to tackle some pretty amazing concepts. Some science experiments for high school are just advanced versions of simpler projects they did when they were younger, with detailed calculations or fewer instructions. Other projects involve fire, chemicals, or other materials they couldn’t use before.

Note: Some of these projects were written as classroom labs but can be adapted to become science fair projects too. Just consider variables that you can change up, like materials or other parameters. That changes a classroom activity into a true scientific method experiment!

To make it easier to find the right high school science fair project idea for you, we’ve rated all the projects by difficulty and the materials needed:

Difficulty:

• Easy: Low or no-prep experiments you can do pretty much anytime
• Medium: These take a little more setup or a longer time to complete
• Advanced: Experiments like these take a fairly big commitment of time or effort
• Basic: Simple items you probably already have around the house
• Medium: Items that you might not already have but are easy to get your hands on
• Advanced: These require specialized or more expensive supplies to complete
• Biology and Life Sciences High School Science Fair Projects

Chemistry High School Science Fair Projects

Physics high school science fair projects, engineering high school stem fair projects, biology and life science high school science fair projects.

Explore the living world with these biology science project ideas, learning more about plants, animals, the environment, and much more.

Extract DNA from an onion

Difficulty: Medium / Materials: Medium

You don’t need a lot of supplies to perform this experiment, but it’s impressive nonetheless. Turn this into a science fair project by trying it with other fruits and vegetables too.

Re-create Mendel’s pea plant experiment

Gregor Mendel’s pea plant experiments were some of the first to explore inherited traits and genetics. Try your own cross-pollination experiments with fast-growing plants like peas or beans.

Make plants move with light

By this age, kids know that many plants move toward sunlight, a process known as phototropism. So high school science fair projects on this topic need to introduce variables into the process, like covering seedling parts with different materials to see the effects.

Make Wild Sourdough

It seems like the whole world is baking homemade sourdough bread right now. Sourdough took on broad appeal when the baker’s yeast disappeared from store shelves. Unlike other baking projects, sourdough doesn’t need store bought yeast. Instead, it’s made with sourdough starter.

RELATED: FREE SCIENCE EDUCATION E-BOOKS

If you have flour, you can easily experiment with making your own sourdough starter.  Wild sourdough starters  tap into the abundant yeast in our homes and puts them to work making delicious bread. When it comes to science experiments you can do at home, few could be more delicious and rewarding than this one. You’ll also be helping scientists out along the way.

RELATED: BACK TO SCHOOL WITH CITIZEN SCIENCE

The Wild Sourdough Project is a global science experiment that hopes to discover how sourdough starter communities form over time. The team behind the effort is hoping to unravel how factors like geography and different kinds of flour affect the yeast communities. Best of all, the effort has a step-by-step guide that lets you learn how to make your own sourdough starter.

Create a Cloud in a Jar

Clouds are an important and often overlooked driver of Earth’s temperature. They trap sunlight in, but they also reflect it back into space. That role has climate scientists rushing to study our planet’s clouds, and how they’re changing.  NASA’s GLOBE Observer: Clouds  project taps citizen scientists to provide pictures of the sky, plus observations of cloud cover, type, sky conditions and visibility. That data helps info real science research and verify what satellites are seeing from space.

You can get involved with your kids and enrich the experience by adding lessons about clouds. For example, NASA has added a number of fun and easy ways to learn about climate science and clouds, including science experiments. One of the best related projects is to make a cloud in a jar. This simple science experiment is a powerful way to demonstrate how clouds work. You only need water, ice, a jar, and a few minutes of time.

Take Part: Join NASA’s Globe Observer Clouds

Measure Rain and Snow with CoCoRaHS

Fall is approaching fast, which means many of us will soon be at home watching rain and snow out the window. Instead of succumbing to the gloom, why not make that weather into a fun science experiment for your kids?

The CoCoRaHS weather monitoring program, or Community Collaborative Rain, Hail, and Snow Network, is a network of volunteers who measure and report on precipitation. CoCoRaHS emphasizes training and education, and they even have an interactive website rich in educational resources and even National Weather Service lesson plans you can use at home.

RELATED: Getting Creative with Remote Science Learning

As a volunteer, you’ll use the same low-cost weather gauges that meteorologists and cities use. Then, when it rains, snows or hails, you’ll submit your precipitation data to the website where you can compare it to others in real-time. That information also helps out the National Weather Service, as well as researchers, farmers, emergency managers — and curious people everywhere.

Take Part: Join the CoCoRaHS Weather Monitoring Network

Plant a Pollinator Garden

Pollinators play a vital role in Earth’s ecosystems, and yet they’re threatened by pesticides, disease, habitat loss and even climate change. That has many people searching for  ways to help save bees and other pollinators .

There are many options to chip in, but one of the most impactful things you and your kids can do at home is  plant a pollinator garden .

Not only will this serve to help struggling pollinators, it can also serve as a long-term science laboratory at home. SciStarter, the citizen-science group behind this blog post, has compiled an entire group of at-home science projects that can be done from your pollinator garden. You can watch moths, butterflies, bees, hummingbirds and more, then help scientists track their migration across the country.

Take Part: Plant a Pollinator Garden

Build a Bee Condo

If you already have a bumper garden at home, or it’s getting too cold to think about planting just yet, you can still stay indoors and help pollinators. The group behind National Pollinator Week has put together instructions for how you can build a home for native bees, called a bee condo. Unlike domesticated honey bees that live in apiaries, most native, wild bees you find in your backyard actually burrow their homes into the soil or a tree.

By building a bee condo, you can encourage bees to live nearby and also get a fun, DIY science experiment to do at home. Once it’s up, you can watch what kinds of critters take up residence there and report back on the results for science.

Take Part: Build a Bee Condo

Scan the Night Sky

Around the world, light pollution from buildings and street lamps is blocking our view of the night sky. Most people who live in cities have never seen a truly dark sky, or the Milky Way. That’s not just bad for humans, it’s also bad for the plants, animals and insects who are disrupted by light pollution.

If you have a budding astronomy-lover in the house, you can participate in a science project called  Globe at Night  that aims to create a world-wide measure of light pollution in our night sky.

For this science experiment, you can start making observations using only a smartphone. You’ll mark the sky’s darkness by how many stars you can see. And you can get a sky quality meter through the project to help record even better data.

Take Part: Measure Light Pollution in Your Community

Measure Water Quality

More than 1.5 million volunteers from across the planet are already taking part in a science experiment to track — and protect — Earth’s waterways. The citizen science effort is called the  EarthEcho Water Challenge , and it has users buy a water test kit for about $25, then start collecting basic water data.

Volunteers record things like water clarity, temperature, pH and dissolved oxygen. That data gets plugged into a large database, where it’s used for real science research and to help protect waterways.

Take Part: Join the Earth Echo Water Challenge

Study the Vitamin C in Your Juice

Back in the golden age of sailing, sailors worried that they’d get scurvy. A lack of vitamin C during long voyages can cause a host of health problems. Scurvy leaves you weak, causes skin problems and gum disease, and makes it harder to heal. Scurvy can even kill you. This isn’t just an old-timey concern, either. Future space explorers will have to worry about vitamin C as they head off to explore the solar system. And that’s the angle utilized by a fun citizen science project called  Space Scurvy .

The project asks students to use household items to test the vitamin C content of juices from their schools and homes. The necessary tools for this science experiment should be easy to come by, and the site has fun and simple directions for you to follow.

Take Part: Measure Vitamin C for the Space Scurvy Project

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

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!"

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.

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.”

FOCUS ON RESEARCH

The best science fair projects often start with research about the main concepts and background. Generating a question is important, but finding information on the topics in the science projects is just as worthwhile.

You cannot just expect kids to know how to do research. Instead teach them how to choose keywords for their topic, and how to search them online. Focus on words that answer who, what, where, and when of the topic.

Remember that searching a complete question can limit results. Instead of searching “What does the frequency of watering have on plant growth?”, your kids will do better to search “plants and water consumption”.

Using the library to research a science project is also an important skill. Teach kids how to use the library to find books related to their topic as well as research databases that their school subscribes to.

Remind them that the purpose of research is to build background on their topic and find out how to conduct experiments. They should still complete the project on their own and not copy what others have done.

EXAMPLES OF RESEARCH-BASED SCIENCE FAIR PROJECTS

COLLECTION-BASED SCIENCE FAIR PROJECTS

Another way to put together a science fair project is with a collection such as a mineral collection or a shell collection.

The big picture of putting together this type of science project is in the labeling. How do you label a collection? That’s the key to success! Labeling helps you to quickly identify each item and important facts can also be recorded. You may choose to put a simple number on an item and then create a corresponding card with the correct information.

CHOOSE INEXPENSIVE MATERIALS

Encourage your kids to choose science project materials that are easily available at school or home. There is no reason to buy expensive electronics or chemicals for a science project. 

Experiments can be done with water, plastic bottles, plants, food coloring, and other easy-to-use and find materials at home. Inexpensive science project materials are everywhere. See our list of must-have STEM supplies for more ideas!
