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.

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

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 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.

What is a compound microscope? Kids find out by making one of their own in this cool science fair project.

This science fair project idea investigates whether air has mass and weight.

The project investigates how friction affects motion by using different surface textures.

This simple heat transfer experiment is a great introduction to the concepts of heat transfer and conduction.

This project explores ways to prevent static electrical shocks.

This science fair project idea investigates how the height at which a pendulum is released affects the length of time it continues.

This science fair project idea examines liquids of different densities.

This science fair project idea discovers whether there are some objects that do not fall at a constant rate.

Science fair project which determines whether the size or the thickness of a piece of paper has an effect on how many times it can be folded in half.

This is a fantastic and easy science experiment where kids will learn about elasticity by testing how high bouncy balls of different materials can bounce.
