This science fair project idea explores which fruit molds the fastest.

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.

Did you ever add salt to pasta? Did it help cook the pasta faster? If not, find out in this science fair project idea.

In this science fair project, students use the streak test to tell minerals apart from each other.

This experiment examines whether storing your orange juice at different temperatures affects its acidity.

Soil and energy don't go together, right? That would be as bizarre as a pairing of peanut butter and marshmallows! Well, actually...

This science fair project teaches students the differences between fruits and vegetables.

This science fair project idea studies which kind of rock (sedimentary, igneous, or metamorphic) is most damaged by frozen water.

This science project teaches students to classify different shapes of leaves.

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.

This is a quick, easy science fair project that conveys the idea of density to upper elementary students.

This science project challenges students to learn about and classify weeds and discover new practical uses for weeds.

Science fair project that examines what causes thunder and why a thunderclap sounds so loud. How is lightening related to the creation of sound waves?

Discover whether cold or hot water from the faucet will boil faster on the stove.

Kids will learn about insulation, heat conduction, and the economic benefits of energy efficient windows in this cool science fair project.

This science fair project idea creates a sedimentary rock and to investigate what takes place during the rock cycle.

Explore how sound waves are reflected and absorbed by producing echoes. Analyze which locations produce echoes.

Science fair project that develops latent fingerprints on a non-porous objects by converting superglue from a solid state to a gaseous state.

Have you ever noticed the ridges on a dog's nose? In this project, we take several dogs' nose prints and discover just how unique they are!

This experiment has students record rat behavior to learn about the benefits of rats and research rat myths throughout history.

Discover that the absorbency of fabrics depend largely on the shape and structure of the individual fibers that make up the fabric.

Science fair project in which you will learn more about the natural world by preserving and identifying different animal tracks.

Discover how and which salt melts ice the quickest.

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 mint, known for its âcooling sensationâ really does lower temperatures.

This science fair project idea explores substances that cause a bubble to last longer.

In this cool project, create a lighted, scale model of the different layers of the Sun, including the core, radiation and convection zones, and photosphere.

The project investigates which soft drink is worse for your teeth by observing the affect of soft drink on limestone.

The objective this science fair project is to determine whether a bigger bag will allow a homemade hot air balloon to fly higher than smaller bag.
