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.

In this activity, students will be challenged to describe and count the ways a toy moves from one position on a grid to another.

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.

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.

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.

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.

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

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

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?

Kids will make predictions about cricket behavior by conducting this fun and easy experiment which simulates different environments for crickets.

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.

How greasy are your potato chips? Students will use a reliable method to quantify greasiness and compare different brands in this great science fair project.

Will storing cucumbers and tomatoes in the fridge destroy their unique flavors? Find out in this science fair project idea!

Is it amplitude? Weight? Length of string? Kids will discover what factors changing the period of a pendulum depends on in this fun and easy physics experiment.

Which music genres have the fastest tempos? The slowest? This experiment determines if there's a relationship between beats per minute in a song and its genre.

This project investigates the affect of storage temperature on microwave popcorn.

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

What do ants eat? Kids find out by observing a colony of ants in this cool zoology science fair project for 4th grade.

In this activity, your child will be challenged to build a tall tower out of building bricks! The instructions include questions prompts to guide students through the design challenge.

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