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

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.

In this science fair project, students use hot and cold water to simulate what happens when a warm front meets a cold one.

In this science fair project, we learn how air molecules move as a result of density, convection, and air currents.

What is mulch? Kids will provide soil with a wet blanket of mulch and see if that helps keep drought-stricken soil damp.

Science fair project in which you will start a fire from scratch without using matches or a lighter.

In this insulation experiment, you'll learn which clothes keep you warm in the cold, and which make you shiver.

What if the shape of the Earth weren't spherical? How does its shape affect our gravity, climate, and tides? Model these questions in this cool project!

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

In this experiment, your child will create two compost bins and see if he can determine what attracts fruit flies.

Is there more air particulate matter in an urban or rural environment? Test your knowledge with this science fair project.

This project examines the concentration of dissolved oxygen in water, with and without oil.

This project concerns activity happening millions of miles away, on the sun.

The goal of this science fair project is to evaluate the effect of heat on sound wave frequency.

The projects describes the correlation between Gravel Run and Centreville Landing in terms of pH, dissolved oxygen, turbidity, and temperature.
