Here is a fun middle school science project on factors affecting solubility. Learn how dissolved solids can "crash out" to form crystals when conditions change.

In this project, you'll build a model of the earth, complete with all seven continents and four major oceans.

What makes your shadow dance around all day? Let's play detective and find out why that sneaky shadow never stays in one place for long.

Science fair project that determines whether lettuce that is harvested gradually yields more produce than lettuce that is harvested all at once.

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

Using a toy race car kids create a visual model of the Doppler Effect.

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?

In this project, a basketball containing different psi is dropped to see how well it bounces.

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.

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.
