Examine how the tire treads of a bicycle affect its rolling frictional force. Change tires, test speed performance on different terrains.

The project compares three different methods of testing turbidity in water: the secchi disk, spectrophotometer, and turbidity test kit.

Are you ready to pilot your own airplane? Well, then take to the skies with this high-flying project!

Science fair project that demonstrates how a rainbow forms, by using water to split white light into its many colors.

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

This science fair project idea recreates the movement of planetary bodies in order to learn why they sometimes appear to move backwards.

Demonstrate how tracks are formed by pressing your hand into a cornmeal mixture, then reverse the process and make prints of the track.

This science fair project collects information on the Internet about yourself and others.

Science fair project that compares tree leaf size and shape based on the leaf's position in the tree. Is their is a noticeable difference between high and low?

In this experiment, you experiment with laser jet toner, a magnetic fluid, as it moves, bubbles, and forms unique shapes.

What is the hydrologic cycle and how does it work? Check out this fun and easy science project where you will model and learn about Earth's water cycle!

This science fair project idea models industrial oil spills and determines if they have an impact on wildlife living beneath the surface of the water.

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.

This science fair project idea explores whether boiling and freezing water will have an effect on how much it weighs.

Glass is see-through, but usually you can still see that it is there. In this experiment, we use baby oil to make glass go completely invisible.

Learn how different types of soil affect how animal tracks form in this experiment!

Dive into the world of cooking oil and smoke points to discover just how fast some oils start smoking.

The purpose of this science project is to determine which chemical best lowers the temperature of water in a cold pack and if the amount affects its use.

Find out whether optical mice are useful on all surfaces or if there are drawbacks to this supposedly superior solution to the traditional roller-ball mouse.

Find a mathematical relationship between the intensity of a sound wave and distance from the sound source. Use a pedometer and a sound level meter.

Have fun with bubbles and find out why there are bubbles in your tap water in this cool science fair project idea.

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.

In this science experiment, test the pH of soil surrounding a gas station to determine if gas stations have a negative effect on the environment.

The purpose of this science fair project is to determine whether Green Bags, with or without refrigeration, are most effective in preserving food.

Science fair project which examines the chemical reaction of a candle flame with various gases in order to determine the identity of the gas.

In this cool experiment, learn how to find specific gravity of minerals using liquids of different densities to see which substances and items sink and float.

Collect meteorite dust with a magnet in your very own backyard! The objective of this science fair project is to gather meteorite dust to study outer space.

This experiment investigates whether the psychological phenomenon of the halo effect can be used to explain people's perceptions of others.

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

Determine whether cats have dominant paws. Observe which paw cat uses to reach for treats, feather, and string. Calculate percentage for two paws.
