Have your child observe, measure and record the amount of space objects occupy, and you'll have an inside space explorer on your hands in no time!

What is the hydrologic cycle and how does it work? Check out this fun and easy science project where you will model and learn about Earth's water cycle!

This simple experiment serves as an introduction to the greenhouse effect.

Science fair project that examines how temperature affects density and how density in turn affects the behavior of helium gas.

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

Any time is the perfect time to whip up a delicious batch of fluffy pumpkin cookies.

All you need are pencils, paper and some scissors to get started on this easy and fun game to review astronomy information, or other types of study concepts.

If it's Easter, it must be time for egg hunts. But we have to admit, most kids would rather take a bite out of a yummy cupcake than a hard-boiled egg.

In this science experiment, observe convection currents forming and learn about how heat energy moves in liquids from hot to cooler areas through convection.

Science fair project which simulates the global conveyor belts on a small scale, and observes the effects of wind, density and temperature on water movement.

In this cool project, create a lighted, scale model of the different layers of the Sun, including the core, radiation and convection zones, and photosphere.

Kids will learn about insulation, heat conduction, and the economic benefits of energy efficient windows in this cool science fair project.
