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.

Determine whether the application of Febreeze will lower the bacterial count.

This project determines the age of a tree using a growth factor chart instead of cutting the tree down to count the rings in its base.

In this project, you will observe and record changes in sunspots over two weeks.

Is there more air particulate matter in an urban or rural environment? Test your knowledge with this science fair project.

Tree rings can tell the age of the tree but also information about the world. This science experiment uses tree stumps to discover new facts.

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.

Science fair project determines relationship between number and variety of insects and spiders by collecting and counting invertebrates in a ecosystem.

Demonstrate that insects observe colors and choose favorites. Place colored pieces of construction paper on a flat, glassy surface, observe bug preference.

This science fair project introduces children to static electricity and the idea that electricity is more than lights and plugs.

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.

Examine the impact of insecticides on plant growth.

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.

Science fair project that examines the biodiversity of ant populations in various locations.

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

This study observes plants, insects and an animal living in proximity to a known source of EMF.

Science fair project idea that compares number and relative sizes of leaf stomata. Collect leaves of plant species, identify, observe stomata with microscope.

Fibonacci sequences have been observed throughout nature, like in leaves and flowers. In this project, students find examples of the Fibonacci sequence.

In this science fair experiment, students learn about the scientific principles behind Doppler ultrasound.

Determine which seeds are most likely to survive harsh winter conditions (low temperatures).

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.

This science fair project idea explores the fastest average speed a human can talk.

Science fair project which determines whether it is numerically possible to be connected to every person on the earth within six degrees of separation.

Discover whether ants are more attracted to natural cane sugar or artificial sweeteners.

Science fair project that compares the biodiversity of fungi in different ecosystems by identifying species of fungi.
