An important key to creating an impressive science fair project is choosing one with real science at its heart, rather than one revolving around baking soda volcanoes or similar. If that fails to impress judges, no amount of baking soda volcanoes will do!
Find exciting ideas for biology, chemistry, physics, and environmental science experiments that engage students while building their confidence in the classroom.
Build a Hand That Picks Up Objects
An effective science fair project must be creative, engaging, and compelling; it should demonstrate the scientific method and be presented and displayed properly.
Find something that really interests you, then conduct your own experiment to test a hypothesis and record findings in a lab notebook. Possible experiments might include testing magnetism strength and measuring how a balloon floats.
Test the Electrolytes in Sports Drinks
Students can experiment with electrolyte levels found in sports drinks to see if they help recover after exercise, making this experiment both nutrition and chemistry-oriented and perfect for 7th grade science fair projects.
Explore chemistry through this bubbling lemonade recipe or create chromatography art to learn about separating mixtures. Discover how different temperatures impact bubbles for an engaging scientific experiment that will make your science fair board shine!
Build a Geodesic Dome
Geodesic domes, pioneered by Buckminster Fuller to revolutionize human shelter, are striking.
Dome structures use triangular supports to bear heavy loads while resisting strong winds, making them one of the strongest buildings in architecture.
Domes can often be constructed using eco-friendly building practices and recyclable materials, making this project ideal for a science fair project that promotes sustainability in building practices.
Make a Jar That Warms the Atmosphere
GREENSBORO, NC — News 2 Science Geeks are here with easy science experiments you can perform at home this week – like creating a cloud in a jar!
An effective science fair project poses a question and conducts experiments to address it, while providing an opportunity to demonstrate and explain your experiment’s results to others.
Make a Car That Balances
Science fair projects often involve collecting data, testing hypotheses and communicating results. Furthermore, these projects allow children to practice using the formal scientific method by asking questions, designing experiments and collecting data.
Want to impress the judges at your next competition? Try this fingerprint classification project on HubPages or try finding T-Rex’s closest living relative in this forensic science experiment? Both projects offer kids plenty of exciting potential research topics!
Build a Battery
Harnessing electricity is one of mankind’s great accomplishments, and you can experience its wonder for yourself by creating your own battery. To build one you will need copper pennies and aluminum foil as well as water, scissors, salt and a multimeter.
Kids can conduct an experiment using Science Buddies’ cool science fair idea: testing voltaic pile of coins. By creating an electric current from one penny onwards, this test can reveal exactly how many pennies are necessary to form one electric current.
Make a Spring That Measures Weight
Explore how weight affects the distance traveled by a rubber band car in this eighth grade science experiment.
Put your favorite laundry detergent to the test in this engaging chemistry experiment!
STEAMsational has created an amazing germs science fair project idea where students can explore osmosis. Kids can conduct the “naked egg” experiment or simple spherification experiments to show off their knowledge to judges at science fair.
Build a Solar-Powered Desalination Device
Kids’ science fair projects can make a splash at school science fairs, stunning judges with projects that explore physics, biology and beyond.
This solar-powered desalination device could potentially help alleviate water shortages in developing nations. Understanding its process by building this model and seeing first-hand how solar rays can heat and power appliances are also demonstrated here.
Build a Pet Feeder
Be a hero to your cat by creating their pet feeder out of empty plastic juice, water, or soda bottles! All it will take to complete this project are some bottles and scissors plus 30 minutes to put together this impressive project that would impress judges!
Discover chemistry by creating your own battery using All Science Fair Projects’s fun science experiment or testing different paper airplane shapes to see which ones fly the best.
Make a Cellular Mitosis Model
What do your intestines, bread dough yeast and an emerging frog have in common? All three need mitosis — the process by which cells divide to create two genetically identical copies — for survival. Use this hands-on model of mitosis’ four stages — prophase, metaphase, anaphase and telophase — as a learning experience!
At prophase, replicated chromosomes form lines parallel to the equator and form pairs of socks tied together as an effective simplification technique.
