Introduce your second grader to the crazy world of static electricity with just a balloon and a sheet of paper.

In this challenge, students are tasked with creating a car that can be powered by a balloon!

In this air pressure science experiment with a balloon and a jar, children will use heat to create a partial vacuum and suck a balloon into a jar.

Think you can blow up a balloon without using your mouth? This isn't just a cool trick, it's also a great way to introduce chemistry and biology concepts.

This balloon-powered car project is a great way for your kid to learn about energy and how it can be used efficiently.

Your child will learn science and make a fun new malleable toy with this balloon sandbag science experiment.

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

Celebrate April Fools' Day with a science prank that is sure to amuse...and educate too!

In this science fair project, kids start a chemical reaction that will make a balloon inflate itself!

Teach your kids about entropy with this fun, easy exercise, and teach your money to dance while you're at it!

Get your sense of humor ready for this fun science experiment that demonstrates the fundamental physics of air pressure.

Set your young chemist up for an afternoon of science-fueled magic with a deceptively simple activity starring baking soda and vinegar!

How powerful is the reaction between baking soda and vinegar? Find out here!

Water can go from solid to liquid to gas...but how does popcorn go from kernel to snack? Invite your first grade scientist to find out.

This 4th of July, explore fourth grade science and make some safe fireworks in your own backyard using soda pop!

Your child might have noticed how bubbles quickly lose their colors and pop. Check out this creative way to make those bubbles last longer.

What's cooler than an explosion? Not much! This simple science experiment lets kids build their own pop rocket. So put on your safety goggles and let her rip.

Explore the chemistry of latex polymers with this outrageous, hilarious science 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?

This experiment investigates whether there are certain sounds that affect men and women differently

This science fair project idea produces sounds by creating vibrations using different objects.

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.

Demonstrate how we are able to locate sounds, echolocation. Have a blindfolded subject locate you by the sound of your clapping.

This project examines Newton's First and Second Laws of Motion with a bicycle and water balloons.

Air invisible; it doesn't make sounds; you can't pick it up and throw it. So how do we know it exists? Help your second grade scientist figure it out.

In this project students determine which instruments composers use to create birdsongs and birdcalls in classical music.

Find out the differences (if any) in the frequencies of voices produced from a computer, from a phone, and directly coming out of the voice box of a human.

Your third grader will delight in learning about sound waves as he observes the different sounds created by tapping on glasses with varying amounts of water.

This homemade barometer allows your little scientist to contemplate and compare different air and weather conditions.

In this Halloween-themed activity, young learners will find out what happens when they mix two household items together to create a surprising chemical reaction.
