Step into the fantastic world of colors with a project that explores what shade you -- and your friends -- like best.

How do organic materials become soil? This science experiment measures what materials biodegrade.

This science fair project will help students learn about non-vascular plants, such as mosses.

Children have a naturally inquisitive mind. Foster their curiosity with a walk through an autumn field or park to answer age-old “why” questions. As you walk with your child, you can encourage them to ask questions.

This experiment has students record rat behavior to learn about the benefits of rats and research rat myths throughout history.

What is a compound microscope? Kids find out by making one of their own in this cool science fair project.
