This project compares the strength of one, two, and three-ply toilet paper.

In this project, waves of vibrations are experimented with using water in glasses.

The goal of this golf science fair science fair project is to determine whether the temperature of a golf ball affects its elasticity and its rebound.

These science fair experiments demonstrate the chemistry of rust and the oxidation process.

Science fair project examining barometric pressure, and how it can be used to predict the weather. How does atmospheric pressures relate to weather conditions?

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.

Learn about the microclimate of your backyard by tracking rainfall, temperature, and observed weather with hand drawn charts and graphs.

How does frost form? How fast does it form? Do this simple science project using a plastic glass, rock salt and some water to learn about deposition.

Will potatoes spud or sprout faster in dry, dark, or cold conditions? Find out in this science fair project idea!

In this popcorn experiment, students can explore how two things made out of the same material can have very different appearances and densities.

Marshmallows are made of sugar, water, and air pockets. Since the marshmallow is flexible, will air pressure cause it to expand when heated in a microwave?

This science experiment examines the role of fat in food, especially in making bread rise and whipping cream.

The moon doesn't produce its own light, so why can we see it shining in the sky? Learn about reflection and planetshine in this fun and easy science project!

Cherries usually burst with flavor, but in this science experiment they burst with osmotic pressure. This science activity will blow your curious kid's mind!

Science fair project that examines how winter storms form and the relationship between temperature, moisture and snow.

Science fair project that examines the behavior of water and gravel in creek beds and the formation of sedimentary rocks.

Learn about savanna flora and fauna in this science project! Take a look at characteristics of tropical grassland plants and animals that help them survive.

Learn about sound physics and do a survey experiment to explore the difference between sound and noise in this science project.

Learn about the role of Earth's rotation on the Coriolis Effect and hurricanes in this science project. Model the Coriolis Effect on a hurricane's direction.

The project investigates how friction affects motion by using different surface textures.

Tired of gum with flavor that lasts for just a couple of minute? Put gum to the test with this chewy science experiment!

In this experiment we will be determining whether birds prefer certain colors of seed.

This science fair project idea explores whether talking to a plant will help it grow.

This science fair project idea explores how length affects the weight a bridge can hold.

In this activity, your learner will be challenged to create their own tic-tac-toe grid out of building blocks.

Collect meteorite dust with a magnet in your very own backyard! The objective of this science fair project is to gather meteorite dust to study outer space.

Young scientists will investigate people's preferences for saltiness, and make some inferences about genetics and diet.

Science fair project which determines if plants really do need water to grow, or whether they just need to be kept wet.

In this project students experiment with making music using only glasses of water.

Kids will learn some cool stuff about chemical reactions by determining what happens when you mix different concentrations of hydrogen peroxide and yeast.
