Here's a fun math and science activity: help your child explore four different kinds of measurement, using their hand and a few simple household tools.

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

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.

Chlorine and chloramine are added to our tap water to kill harmful microorganisms. What is the best way to filter these disinfectants in your drinking water?

Kids learn about examples of mechanical weathering and conduct an experiment with seeds and plaster in this cool geology science fair project idea.

Put your young paleontologist's puzzle-solving skills to the test by having her hunt for dinosaur bones and then assemble them to create dinosaur skeletons.

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.

Learn how to make a ping pong ball anemometerâa device used to measure wind speedâin this free science fair project idea.

Here's a fun at-home activity that will help your child strengthen math skills using high and low temperature data, and become a master temperature tracker!

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

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

This simple "how to make a water wheel" activity makes physics come alive for your child by demonstrating how different kinds of energy work.

In this free science fair project, build a star clock and learn how to tell time on a clear night by observing the big dipper!

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

What causes the seasons to change? Kids find out by modeling the earth's tilt using a globe, flashlight and graph paper in this cool science fair project idea.

Here is a fun middle school science project on factors affecting solubility. Learn how dissolved solids can "crash out" to form crystals when conditions change.

This science fair project idea demonstrates that plants give off water.

This experiment evaluates if a noisy environment makes it harder for test subjects to perform tasks that require hand-eye coordination.
