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.

Start your toy engines -- this is going to be a fast and friction-filled race!

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

This science fair project creates a visual model of whatâs happening to sound waves as a car approaches and then leaves.

examine how passive solar heating works, measure temperature in a parked car on a sunny day. ways to use passive solar heating as an alternative, energy

Can a toy car determine the strength of a magnet? In this cool magnet science fair project, young scientists will learn how to measure the strength of a magnet.

Science fair project that examines albedo, and how this information is applied in the design of cars, sportswear, and other items. Which colors reflect light?

Stories change as you retell them. The objective of this science fair project is to demonstrate how information gets interpreted, distorted and changed.

This science project challenges students to study deer behavior in their natural habitat- the feeding patterns, social behaviors, male to female ratio, etc.

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

This fun science fair project idea helps students learn how acid rains are formed and explore how acid rain damages the environment.
