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

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 design challenge, students will be tasked with creating a bouncy ball polymer!

In this cool catalase and hydrogen peroxide experiment, kids put a potato in a jar of hydrogen peroxide to see how catalase acts as an enzyme.

This science fair project idea investigates which objects float and sink in honey, water, and oil.

In this cool engineering science fair project, kids learn how to build Hero's engine: an enlightening example of Newton's third law.

What is elasticity? Students will investigate how this concept applies to bouncing ball physics by testing the bounces of balls made out of different materials.

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

What cause the phases of the moon? Make a model to see how the positions of the Sun, Moon, and Earth cause the crescent, gibbous, quarter, full, and new moon.

This middle school science fair project determines whether DNA is most easily extracted from under-ripe, ripe, or over-ripe strawberries.

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.

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 is a quick, easy science fair project that conveys the idea of density to upper elementary students.

In this science fair project, students discover how sedimentary layers form as sediments like mud, silt and sand settle over time.

How does rust form? Kids will learn about the roles oxygen, water, and electrons play in rust chemistry in this cool science fair project idea.

Challenge your learner to design and build a city of their own in this creative engineering activity.

The buoyant force of water explains why some objects float in water. But why do some objects sink? Find out in this physics experiment and learn about density.

This project will explore whether test subjects, deprived of points of reference, will, in attempting to walk a straight course, walk in circles.

This science fair project idea creates a sedimentary rock and to investigate what takes place during the rock cycle.
