Kids learn about examples of mechanical weathering and conduct an experiment with seeds and plaster in this cool geology science fair project idea.

Check out this cool science fair project idea to explore the risk of mechanical deterioration of artifacts placed in a storage box due to mold outbreaks.

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.

Kids get step-by-step instructions for how to make a rubber band car and explore the physics of potential energy with this fun engineering science fair project.

Kids learn about potential energy, and mechanical energy, and how to make power from water with one of our favorite renewable energy projects for kids.

Science fair project which teaches you about the principles of physics within a vacuum by creating a vacuum chamber.

In this cool physics experiment, use double plane mirrors at various angles to learn about light reflection. Then, see if you can solve a puzzling problem!

In this science fair project, apply the principles of leverage and force by building six simple machines designed to set weights in motion.

Glass is see-through, but usually you can still see that it is there. In this experiment, we use baby oil to make glass go completely invisible.

This science fair project idea develops an understanding through experimentation of which shapes are the most structurally strong.

This science fair project idea studies which brand of wintergreen candy produces the most sparks in the dark.

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

Find out whether optical mice are useful on all surfaces or if there are drawbacks to this supposedly superior solution to the traditional roller-ball mouse.

In this windmill model science project, you will build a windmill to learn about wheel-and-axle machines and how these simple machines are used to do work.

This basketball project explores the best way to make the perfect shot every time.

This science fair project idea explores whether a plastic slinky works as well as a metal slinky when walking it down the stairs.

Science fair project about work and energy which uses a simple mathematical formula to predict how far a jar will roll down an incline.

Find out whether cast iron or regular teflon pans heat up faster and also retain their heat longer.

Find out which kind of bubble wrap fares best when put in impact.

Find out which type of sponge holds the most water.

Demonstrate how static electricity can cause an object to move. It also examines just how an object affected by static electricity will move.

This science fair project demonstrates the magic of arches by challenging students to stack telephone books on top of eggs without breaking them.

Young physicists will wrestle with a discrepant event: the Hammer Ruler Trick. They'll make some inferences about torque, balance, and center of gravity.

This science fair project idea explores how much force is needed to move a lever at different distances from the fulcrum.

This science fair project idea investigates if heat from direct sunlight is hotter than heat from reflected sunlight.

Science fair project in which you will attempt to throw a ball the greatest horizontal distance possible by using different angles.

The objective of this science fair project is to test the growth rate of a plan in a crystal medium in comparison to traditional soil.

In this Bernoulli's Principle experiment, you'll learn how an increase in the speed of a fluid, like air, decreases pressure.

In this science fair project, students focus sunlight with a magnifying glass and trap shorter waves to melt ice.
