This science project teaches students the relationship between compost and plant growth. Students conduct an experiment with different types of compost.

There are many benefits to bugs and insects. This science project shows how cockroaches, termites, and other critters benefit our planet.

What's the best way to make DIY compost? Kids will learn about aerobic and anaerobic decomposition while learning to appreciate the value of composting.

Do you think heat can affect a plant's growth rate?

Have your kid determine if a goldfish can be conditioned to expect food the same way Pavlov's dogs did with this fascinating science fair project.

Ever wondered how a plant drinks water? This science project will teach you how and help you create a beautiful floral display!

This science fair project idea explores whether the process used to dry the beans we eat for food renders them unviable.

This science fair project idea examines whether adding gelatin causes a solid to have a higher melting point and/or melt slower.

Determine whether butterflies like to drink sugar water, salt water, or plain water.

In this science fair project, apply the principles of leverage and force by building six simple machines designed to set weights in motion.
