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

Kids will conduct a cool limewater carbon dioxide test that can be performed with common household materials to learn about the chemistry of this common gas.

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

In this challenge, students are tasked with creating a model roller coaster that a marble can travel through.

Students pit the heat capacity of water against the heat capacity of oil while looking at the effects of dipole rotation in this cool science fair project idea.

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