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.

Science fair project that examines learn how the angle of incidence affects the efficiency of solar panels. How does a solar cell work?

Determine which environment keeps an ice cube frozen for the longest duration. Inspect and record your observations when cubes melt.

Students will investigate the illumination durations and intensities of different luminous substances of different colors of the spectrum.

This cool physics demo illustrates the simple harmonic motion of a pendulum while teaching kids the important concepts of potential and kinetic energy.

Do you think you can blow down a sand castle with a mighty wind? Find out which material stands up best to erosion in this erosion experiment.

Kids learn how to prevent erosion by growing grass. They'll test soil with grass against raw soil in this revealing science fair project idea for 4th grade.

This science fair project idea quantifies the effect of specific food sources on red worm (Eisenia foetida) livelihood.

4th graders construct an ocean food web to learn about consumers and trophic levels, food webs, and food chains in this cool ecology science fair project.

High school kids learn about fruit fly ethology in this cool lab that determines fruit fly movement and behavior under different conditions. Check it out.

What is elasticity? Students will investigate how this concept applies to bouncing ball physics by testing the bounces of balls made out of different materials.

Kids build a desert food chain, desert food web, and desert food pyramid in this cool science fair project to learn about trophic levels and consumers.

Saturn is the ringed planet in our solar system, a gas giant with rings made of ice and dust. Let's make a cool scale model with an old CD and some glitter!

The objective of this experiment is to evaluate the effects of acid rain on plants.

The goal of this project is to create an exciting topographical map out of dough.

The objective of this science fair project it to determine whether adding ethanol alcohol to gasoline slows the run time of a motor.
