How sensitive is your skin? Here's a fourth grade science experiment that lets your child figure it out.

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

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.

A homemade lava lamp gives any room a retro flair. Find out how to make a homemade lava lamp, and learn some science too, with this educational activity.

Science fair project that examines what causes thunder and why a thunderclap sounds so loud. How is lightening related to the creation of sound waves?

Try this experiment to give your curious kid a more "solid" understanding of how temperature affects the states of matter.

How does the size of a vibrating surface affect the pitch of a drum? Learn about drum size and pitch with this easy science fair project idea.

This science fair project idea produces varying pitches of sound.

Every time a sound is produced it emits a sound wave. This experiment demonstrates how sound travels, using nothing more than a spoon and a string!

The purpose of this science fair project is to build a basic radio.

Help your kid feel like a superhero with this safe and fun science experiment that creates an electrical charge that's like a mini lightning bolt!

Teach your child some scientific basics as you explore the densities of various liquids in this fun experiment.

The pinwheel is a simple toy that has been around for years and uses the wonders of the wind to spin it and delight kids of all ages!

Make your own helicopter using a paper clip and a sheet of paper. Hold the spinner up in the air, let it go, and watch it spin gracefully to the ground.

This experiment uses a yeast solution, liquid detergent, and hydrogen peroxide to produce an exciting reaction like no other!

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

Your kid can learn about the process of making frozen yogurt and enjoy a homemade, flavorful dessert. Experiment with this fun, chilly food!

Your child will do a fun science experiment using soap and pepper flakes to help understand the concepts of water molecules and the surface tension of water.

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

In this science experiment, your child will test the strength of hollow structures in order to understand how strong bird bones really are.

In this physics project, learn about the relationship between light intensity and distance using a laser pointer, flashlight, and graph paper!

Try the classic balloon-on-the-wall trick with your kid and watch static electricity in action.

Turn the common pastime of constructing paper airplanes into a lesson on the physics of aerodynamics and flight with this fun science activity.

How to test for acids and bases? In this activity you and your child can make your own indicator from red cabbage!

The next time you've got a restless second grade earth scientist on your hands, use this experiment to demonstrate crystals and make a tasty treat, too!

Science isn't ho hum anymore when it involves building catapults to teach your fifth grader about projectile motion.

If your science savy third grader is up for a challenge, let her bend light with a casserole dish!

Check out this mind-blowing experiment in which a hard-boiled egg will fit through an impossibly small opening with the help of only a few matches!

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.
