This science fair project introduces children to static electricity and the idea that electricity is more than lights and plugs.

In this simple circular motion experiment, you'll observe tangential velocity and learn about how acceleration and centripetal force affect an object.

Using a toy race car kids create a visual model of the Doppler Effect.

How do we know that air exists when we can't see it, taste it, or touch it? Here's a classic experiment that will teach your kid some basics of aerodynamics!

In this science fair project, young children discover what happens when two fluids that have different densities get together.

Find out whether a longer airplane will fly farther or a wider paper airplane.

Find out whether cast iron or regular teflon pans heat up faster and also retain their heat longer.

Find out which kind of bubble wrap fares best when put in impact.

In this science fair experiment, children demonstrate the relationship between the amount of stuff and the amount of pressure in a closed system.

Find out which type of sponge holds the most water.

In this sound experiment children listen for differences as they tap on a bag of air, a bag of water, and a wooden block held up to their ears.

Experiment with buoyancy to learn how a submarine rises and sinks in this classic science experiment.

This trick uses vertical and horizontal forces to help your child to push apart your hands apart, no matter how hard you try to keep them together!

What happens when colored beams of light mix? You might be surprised.

Demonstrate how static electricity can cause an object to move. It also examines just how an object affected by static electricity will move.

In this air pressure science experiment with a balloon and a jar, children will use heat to create a partial vacuum and suck a balloon into a jar.

This project compares the strength of one, two, and three-ply toilet paper.

This science fair project idea explores if the length of the string that an object is suspended on has an effect on how fast or slow it swings.

Young physicists will wrestle with a discrepant event: the Hammer Ruler Trick. They'll make some inferences about torque, balance, and center of gravity.

This science fair project idea explores how much force is needed to move a lever at different distances from the fulcrum.

This science fair project idea investigates if webbed feet help a duck (and others) swim.

This science fair project idea investigates if heat from direct sunlight is hotter than heat from reflected sunlight.

Science fair project in which you will attempt to throw a ball the greatest horizontal distance possible by using different angles.

How does a kazoo, the strings of a guitar, or the speaker of a radio make sound? The purpose of this science fair project is to show how vibration makes sound.

This classic children's game demonstrates how sound travels through air vs. through a solid.

In this CD hovercraft science project, students will construct their own DIY hovercraft.

In this Bernoulli's Principle experiment, you'll learn how an increase in the speed of a fluid, like air, decreases pressure.

Here's a great activity that uses corks and toothpicks to create a fleet of floating boats. Which design makes for the most seaworthy vessel?

This science fair project demonstrates the principles of reflection through simple experiments involving mirrors and light.

Demonstrate how you can make your own compass using a magnetized needle. It also allows you to compare magnetic north and geographic north.
