When we get hot, we sweat. The physiological role of sweat is to cool us down. When the water evaporates, it removes energy from our bodies. This sort of evaporative cooling can also be used to cool homes, using what are referred to as...

Hydrogen peroxide (often used as a disinfectant) has also been approved for use in pesticides. This science fair project investigates whether hydrogen peroxide has any effects on seed germination or on roots of plant cuttings.

Some molecules can be either left- or right-"handed." The left- and right-handed molecules have the same number and type of atoms, and their chemical structures look identical, but they are actually mirror images of each other. Many...

In the mid-20th century, people thought of robots as futuristic tools. But in the 21st century, robots are not a figment of our imaginations, but are a part of our reality. Robots even perform tasks that humans can't do. In this...

You might think that plants and animals have little in common with batteries, springs, or slingshots, but they actually do have something in common. Both living and non-living things store and transfer energy from one form to another. In...

We tend to think of plants as immobile, but the tendrils of a vine, such as the morning glory, actually move in response to touch. Tendrils wrap around structures, which give the plant something to grow on. In this science fair project,...

Expanding gases are everywhere, from the kitchen to the cosmos. You've tasted their pleasures every time you've eaten a slice of bread, bitten into a cookie, or sipped a glass of soda. In this chemistry science fair project, you'll...

Renewable energy is the energy that is extracted from natural sources, such the Sun (solar), earth (geothermal), wind, and water (hydropower). These sources are renewable because they can be replenished by the same natural sources within...

In this science fair project, grow the acellular slime mold Physarum polycephalum and test its ability to find the shortest path through a maze.

Has anyone ever told you that you have a magnetic personality? Have you ever heard that opposites attract? These common phrases are both based on the properties of magnets and magnetic electricity. In this science fair project, learn how...

In this science fair project, use a color-based reaction to test how pH affects copper corrosion in pennies.

Simple machines are everywhere, even many of your toys are simple machines. Come visit this science fair project and explore the six types of simple machines. Find out how many are hiding under the hinged lid (yes, another simple...

Watch out. It's Eddy Vortex, Superhero. He swirls, he tumbles, he churns up air and water. OK, maybe eddies and vortices aren't exactly superheroes, but they are powerful regions of air and water flow that you have to watch out for in...

The survival of our ancient ancestors depended on their ability to use peripheral vision to find prey and to avoid predators. Almost everything we do-from riding a bike, to dribbling a basketball, to reading a book-depends on peripheral...

Yo-yo's are a fun toy and there is nothing simpler than a string wrapped between two connected disks. But there's a lot of physics that makes a yo-yo work. In this science fair project, learn more about how and why a yo-yo works. You...

You have probably seen figures showing how human beings are related to chimpanzees, gorillas, and other primates. In this genomics science fair project, you will use bioinformatics tools to generate your own primate family tree.

A concise page that offers a number of bug-related science fair project suggestions.

A descriptive list of chemistry-oriented ideas that answer such questions as: Have you ever wondered what happens inside of an egg when it is hardboiled? How do products like Bounce act to soften clothes after they are washed and dried?...

A website featuring project starter ideas to help students carry out hands-on practical investigations on plants. Some ideas featured on the page include exploring food waste, medicinal plants, enzymes in fruits, and much more! Project...

Presents five ideas for science projects that require simple materials and can be easily done in a short time.

This resource from Science Fairs is a wonderful resource for a wide variety of science fair starter ideas. Use an idea from here and build your own project.

Math Forum provides a list of possible math science fair topics with links to each topic to get an idea of what will be studied and suggested questions to answer. This site also contains links to teacher discussions on Math Fairs.

Clean water is not a given everywhere in the world. In this science fair project, students will investigate whether sunlight could be used to disinfect contaminated water. The Science Buddies project ideas are set up consistently...

In this science fair project, measure the "lift" of a set of balloons and track how it changes over time as the helium escapes from the balloons. The Science Buddies project ideas are set up consistently beginning with an abstract,...
