Science fair project that determines whether mass and weight are the same or different.

The project examines absorbent polymers absorbency in disposable diapers and their unique ecological problem to the environment.

In this cool physics experiment, use double plane mirrors at various angles to learn about light reflection. Then, see if you can solve a puzzling problem!

Design a survival kit. Brainstorm various survival scenarios. Address basic human requirements and natural resources. Describe each tool as well uses.

This fun experiment provides a concrete and visually striking illustration of photosynthesis.

Learn whether Mylar Balloons last longer than Latex Balloons or vice versa.

Have you ever seen fruit decay? Find out if a fruit will rot faster if you open it versus leaving it untouched!

This science project lets students explore the number of spots on a ladybird and how to treat ladybugs with respect.

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.

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.

This science project teaches students about organic farming and the benefits and disadvantages of commercial plant food.

These science fair experiments demonstrate the chemistry of rust and the oxidation process.
