Check out this cool science fair project idea to explore which other common animals besides scorpions glow under a UV Black light.

How fast does light travel in different mediums? Kids conduct a cool refraction experiment in materials like water and air for this science fair project.

Science fair project that determines how your mirror image differs from your actual image and how virtual images are constructed.

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.

In this science fair project, students focus sunlight with a magnifying glass and trap shorter waves to melt ice.

In this project, sunlight is blocked from a leaf in order to see the affect that sunlight has on leaves.

Determine if certain colors of light are more effective for photosynthesis. Plant seeds in cardboard boxes with different light, record visible growth.

Science fair project which compares the rates of photosynthesis for various light sources. Which type of light will be best for photosynthesis and why?

How do series and parallel circuits work, and which produces the brightest light in a light bulb? Construct both in this project and find out!

Ant behavior is closely related to light intensity. This free science fair project idea examines how fast ants dig when they are exposed to to light and dark.

Illustrate the idea of light refraction with this exciting and mystifying experiment.

Construct and experiment with a periscope using reflected light rays to gather an image.

This project tests the hypothesis that dark colors absorb more heat than light colors.

In this experiment a spectrometer is used to analyze the light emitted by burning ion solutions.

What happens when colored beams of light mix? You might be surprised.

Science fair project that examines how light wavelengths affect photosynthesis in the aquatic plant: Elodea.
