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

Wonder why bugs always fly around your lights at night? This experiment determines whether insects are attracted to the heat or the light.

Do you have your isopods straight? Learn about sow bug and pill bug behavior by building a terrarium to study them in!

In this project, create and examine garden mulch to find out what critters live in the messy, muddy layers just above the soil.

Can you plant the insect-attracting borage plant to increase the amount of beneficial insects in your garden? Find out in this experiment!

Cinnamon is tasty, but does it have super powers as well? Find out if cinnamon can repel mosquitoes in this outdoorsy experiment.

Have you ever seen fruit decay? Find out if a fruit will rot faster if you open it versus leaving it untouched!

What is surface tension? Kids will discover how water-skating insects use surface tension to keep from sinking by making a model water walker.

Study the life cycle of the common blowfly as it relates to forensic investigation. Record the first time you see flies, maggots, and eggs.

Wiggly worms are known for staying buried in the soil, but how does that affect plants? Are earthworms and plant growth related?

In this free science fair project idea, we learn about surface tension and how it can support mass—in this case, a floating paper clip.

Soil is made up of different layers. How far down do you need to dig to find the soil horizon, or the place where bits of leaves and branches become soil?

What is biodiversity? Kids will study different areas of their backyards to see which is the most diverse to learn about biodiversity and random sampling.

What do worms eat? Kids find out what kinds of rotting leaves and vegetables worms prefer in this cool compost science fair project.

The purpose of this science fair project is to determine which conditions and materials quicken the composting process to make the best compost.
