If you hold a fire up to a balloon, it pops instantly. What if you could prevent this from happening? In this project, we do just that.

Make your own greenhouse - out of a balloon! Your child will learn how greenhouses work as they plant radish seeds and watch them grow.

Design and build a balloon rocket from an existing design. Think of the ways in which existing designs can be improved, new practical applications

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

Science fair project which uses a camera to observe the surface of a balloon in the moment of its explosion.

Kids conduct a cool balloon rocket experiment in this fun science fair project idea. Does a greater volume of air mean a greater distance traveled?

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.

In this exciting design challenge, your child will use design thinking skills to create a mixture that can inflate a balloon.

The objective this science fair project is to determine whether a bigger bag will allow a homemade hot air balloon to fly higher than smaller bag.

Check out this fun science fair project to make a vinegar and baking soda balloon and demonstrate how gas is created as a result of the chemical reaction.

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

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

Kids will learn how to make a steam powered rocket boat, also called a putt putt boat or a pop pop boat, in this great science fair project for 4th graders.

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

In this fun science experiment, make a balloon car and test it on different surfaces to learn about sliding friction and rolling friction.

The objective of this science fair project is to examine the basic principles of air pressure using simple materials like a balloon, straw and string.

Learn whether Mylar Balloons last longer than Latex Balloons or vice versa.

This project examines how temperature affects the volume of gas in balloons.

This cool science fair project teaches kids about temperature, density and buoyancy using balloons that float with normal air. No helium required!

This project compares test subjects' responses to whining and other "attachment" and attention-getting sounds to determine which sounds are most distracting.

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?

In this project, different brands of microwave popcorn are tested and compared.

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.

This science fair project introduces children to static electricity and the idea that electricity is more than lights and plugs.

In this activity, you'll send your kindergartener on a scavenger hunt to find sounds and create a sound recording. Here's how!

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.
