In this science fair projects, students will grow out the bacteria that collect on air conditioner filters.

How does distance affect the spreading of light? Kids see diffraction and the inverse square law of light in action with this great science fair project idea.

This experiment challenges students to forecast the weather based on the surrounding areas' weather.

Marshmallows are made of sugar, water, and air pockets. Since the marshmallow is flexible, will air pressure cause it to expand when heated in a microwave?

In this experiment, students find out what happens when a less-dense fluid interacts with a denser one, replicating the effect of cooler solid rock on magma.

Could there be toxic chemicals lurking in the cupboards and closets of your home?

What chromosome combinations determine a fetus gender? Use probability to think about whether a sperm and ovum will create a male or female in this project.

What's the science behind those out-of-sight roots? Find out if you can trick roots into growing in different directions.

This science fair project idea explores how far the âdanger zoneâ is from different types of caution signs.

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.

Check out this science project idea to compare organic produce to non-organic produce and how preservatives in food extend the shelf life of goods.

In this experiment, kids will see if pruning tomato plants makes them more fruitful and learn about the factors that contribute to a plant's fruit production.

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

Science fair project about work and energy which uses a simple mathematical formula to predict how far a jar will roll down an incline.

Explore if planting seeds in a certain direction will affect how fast it germinates.

This science fair project idea investigates how the shape of an object affects drag.

This science fair project investigates why the number of visible stars changes from place to place.

Get down to the rubber with this science project that tests the effectiveness of different types of erasers.

Find out whether putting something on top of a plant will inhibit its growth.

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

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

Find out which kind of bubble wrap fares best when put in impact.

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

This science experiment examines the role of fat in food, especially in making bread rise and whipping cream.

Prove that the Earth is not flat. The objective of this science fair project is to measure the angle of the sun and calculate the circumference of the Earth.

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

In this experiment, students will discover how heat and pressure turn clay into slate, phyllite, and finally schist.

In this experiment, you'll make a seafloor spreading model to learn more about how plate tectonics work and create mid-ocean ridges.

In this science fair project, students learn how pressure can make the minerals in a rock line up in the same direction and form bands and foliation.

This science fair project idea explores whether white light can be separated into different colors.
