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

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.

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

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

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

Science fair project the demonstrates Newton's Third Law using a milk carton filled with water.
