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

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.

When you rub a balloon on your head, your hair stands up; but is that true for everyone? Does hair color affect static electricity?

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.

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.

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.

Before Twitter, birds were the ones tweeting, not humans. Have your child discover the magical sounds of nature while recording birds around his neighborhood!

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

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

Your second grader will love this simple soda bottle race car activity. Make a ramp and customize your car for an entertaining way to learn scientific concepts.

Take a closer look at your furry friend (or the furry friend of a neighbor -- with permission) to discover if communication exists between cats and humans.

First grade science often covers solids, liquids, and gases. This silly science explores serious facts about the difference between all three.

What's the quickest way to separate salt and pepper? Let static electricity do the work! Your child will be fascinated by this simple experiment.

Which music genres have the fastest tempos? The slowest? This experiment determines if there's a relationship between beats per minute in a song and its genre.

Beetles come in many shapes and colors. Here's how your second grade child can create his own beetles to paint and play with!

Chemistry is a blast with this backyard bomb made from a sandwich bag. All you need are ingredients from the pantry to create a satisfying, and safe, explosion.

In this project, build an insect model that shows how the head, thorax, and abdomen fit together! Learn insect anatomy by constructing a paper mache critter.

Satisfy your sweet tooth with this easy summer activity! Make homemade ice cream and let your child practice his science skills.

How do we know that air exists when we can't see it, taste it, or touch it? Here's a classic experiment that will teach your kid some basics of aerodynamics!

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.

Put an oatmeal box, a flashlight, and some construction paper together and you have the makings of an incredibly cool bedroom planetarium!

Children are imaginative story-builders. Create a shoebox habitat with your child to put those budding creative instincts to good use.

This experiment works due to a simple principle: plants need light. Build a shoebox maze and watch the plant work though the obstacle course, searching for sun.
