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.

Find out which type of sponge holds the most water.

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

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

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.

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!

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

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

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.

This project tests the hypothesis that dark colors absorb more heat than light colors.

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

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.

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

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

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

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.

In this experiment, students find out what happens when a less-dense fluid interacts with a denser one, replicating the effect of cooler solid rock on magma.

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

In this activity, your child will learn about a style of gardening that uses moss, also called "kokedama."

In this science project, the center of gravity is explored.

In this project, waves of vibrations are experimented with using water in glasses.

The objective of this science fair project is to experiment with balancing everyday objects and observing the the effects of gravity on materials.

Based on the concept of water's "freezing point," this activity entails the lowering of water's freezing point to chill ice cream!

Learn with makes water molecules work with this fun and easy science activity!
