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.

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.

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

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.

Here's a fun at-home activity that will help your child strengthen math skills using high and low temperature data, and become a master temperature tracker!

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.

This science fair project idea identifies clouds as a means of predicting the weather.

This Mother's Day, mix in some fifth grade science learning to create this fabulous fudge!

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.
