This basketball project explores the best way to make the perfect shot every time.

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

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.

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

This science fair project idea investigates how a bottom keel helps keep a boat from rocking back and forth.

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

This science fair project examines how tsunamis travel by simulating a tsunami moving around an island. You will generate a pretend tsunami in a swimming pool.

This science fair project idea develops an understanding through experimentation of which shapes are the most structurally strong.

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

Science fair project about work and energy which uses a simple mathematical formula to predict how far a jar will roll down an incline.

This project demonstrates the correspondence between the volume of water displaced by a submerged object and the volume of the object displacing it.

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

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.

Find out which type of sponge holds the most water.

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

Using an empty tennis ball can and a swimming pool, you will determine if it's possible to have a conversation under water.

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.

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

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

How does water pressure change with depth? Kids learn how pressure works underwater with this cool and easy demo.

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.

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

Will increasing the amount of salt in water effect how slow or fast the water freezes?

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

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

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

In this science fair project, students focus sunlight with a magnifying glass and trap shorter waves to melt ice.

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