This project examines whether people's taste perception is influenced by what they see.

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

What are the effects of colored light on plant growth? Explore plant behavior in this cool botany science fair project and learn about phototropism!

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

In this design challenge, your child will create a parachute for a small toy using typical household items.

In this cool catalase and hydrogen peroxide experiment, kids put a potato in a jar of hydrogen peroxide to see how catalase acts as an enzyme.

Is horse manure a possible energy source in a crisis? Use calorimetry to find out how much energy horse manure can produce in this science fair project.

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

In this fun activity, your child will create their very own solar oven to bake s'mores!

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.

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

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.

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