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

The objective of this science fair project is to set up a compost bin to convert food scraps and organic waste.

This science fair project idea demonstrates that light travels in straight lines and experiments with reflecting light.

Kids conduct a cool balloon rocket experiment in this fun science fair project idea. Does a greater volume of air mean a greater distance traveled?

Brine shrimp usually live in saltwater. Investigate how salt concentration (salinity) affects the rate at which brine shrimp eggs hatch.

The objective of this science fair project idea is to determine if sound travels best through the air, water or a solid.

Will the shape of an ice cube impact how fast the ice melts?

Find out whether a longer airplane will fly farther or a wider paper airplane.

The objective of this science fair project is to study the photosynthesis process and demonstrate the important role that leaves play in the process.

Science fair project which simulates the global conveyor belts on a small scale, and observes the effects of wind, density and temperature on water movement.

This science fair project idea determines if the color of light affects the growth of plants.

Science fair project in which you will attempt to throw a ball the greatest horizontal distance possible by using different angles.

In this popcorn experiment, students can explore how two things made out of the same material can have very different appearances and densities.

This science fair project examines how tsunamis travel by simulating a tsunami moving around an island. You will generate a pretend tsunami in a swimming pool.

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

Examine the effect of pressure on carbonation in soda.

In this fun project, use a memory game to test various age groups and determine whether aging directly affects short-term memory loss.

What cause the phases of the moon? Make a model to see how the positions of the Sun, Moon, and Earth cause the crescent, gibbous, quarter, full, and new moon.

This science fair project teaches you about what makes persimmons so tart and how astringency can be removed by studying the effect of tannins on fruit.

How does rust form? Kids will learn about the roles oxygen, water, and electrons play in rust chemistry in this cool science fair project idea.

This basketball project explores the best way to make the perfect shot every time.

What is mulch? Kids will provide soil with a wet blanket of mulch and see if that helps keep drought-stricken soil damp.

Examine whether distilled water, spring water, or regular tap water yield faster plant growth.

The purpose of this science fair project is to explore whether UV light passes through some colors and not others by looking at blue, red, purple, and clear.
