In this science fair project, you will learn more about wind-powered devices, like pinwheels. Much like pinwheels, we react in different ways to the direction of the wind when we ride bikes, or even try to walk.

In this science fair project, you will investigate how distractions affect your focus on a task, such as driving, by looking at how gaming scores are affected as you're talking on a cell phone or having a conversation with a friend. For...

Around 50 million years ago, the mammalian ancestor of today's whales returned to the ocean. In this genomics science fair project, you will use mitochondrial protein sequencing to trace the evolution of whales and identify their closest...

The moon appears bigger at the horizon just as it is rising over the treetops, than it does later in the evening when it is overhead. This is because our perception of its size changes based on where it is in the sky. In this human...

How do you like your mashed potatoes? Thin and whipped smooth? Or thick and mashed into chunks? Your mouth checks out not just the taste of your food, but its viscosity, or how it flows on your tongue, every time you take a bite. In this...

Do you like to watch hummingbirds? Have you ever wondered why there is specialty hummingbird food? What is it about the food that makes it so appealing? In this zoology science fair project, you will observe these remarkable creatures...

A cricket as a thermometer? Yes, that's right. In this science fair project, you'll investigate how the chirps of these tiny creatures can do more than lull you to sleep-they can tell you the temperature.

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.

Have you ever pulled a muscle or just been sore after a long day of work or exercise? Hot showers are great, but maybe you've used the more convenient heat packs. Heat packs, which you can buy at grocery or drug stores to soothe aching...

Have you ever seen a great movie and then rushed out and bought its soundtrack? Did the soundtrack bring back the thrill of an action chase? Or the sadness one of the movie's characters felt? Music is a big part of the movie experience....

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...

Do you enjoy singing contests like American Idol? Well, male songbirds have their own version of a singing competition that has been going on for thousands of years, and classical musical composers have been taking notes. In this music...

Did you know that some teachers give their students a peppermint candy on state testing days? Is it to give the kids sweet-smelling breath? Or are the teachers hoping for something more on the important testing day? In this human biology...

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...

It's hard to believe that the same water that you use every day to quench your thirst, cook with, bathe in, swim in, and wash your clothes and dishes, is capable of another trick-it can make electricity. Electricity can be generated...

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.
