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.

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.

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

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

Here's a fun activity to help build thinking skills in young first grade scientists, and to encourage them to have a blast exploring the mass and volume.

Try this simple 2nd grade science experiment to teach your child about the principles of luminosity and light reflection.

If your fourth grader is obsessed with all things glow-in-the-dark, then here's an activity that will really light up her imagination!

By using static electricity generated from their body, a child can cause a small fluorescent lamp bulb to light up!

Bring the magic and mystery of the night sky to the light of day with this fun constellation art project!

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

Learn about magnifying glasses, concave lenses and inverted images by sending rays of light through a magnifying glass in this cool science fair project!

Science fair project that examines albedo, and how this information is applied in the design of cars, sportswear, and other items. Which colors reflect light?

Science fair project which compares the rate of temperature change and the maximum temperature as a result of the angle of light radiation.

You don't need to wait for rain to see a rainbow. Make one yourself, and teach your child about light and weather in the process.

Believe it or not, images that are cast upon your eye's light-sensitive screen (called the retina) are upside down. Here's a fun, fast experiment to prove it!

The moon doesn't produce its own light, so why can we see it shining in the sky? Learn about reflection and planetshine in this fun and easy science project!

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!

This experiment works due to a simple principle: plants need light. Build a shoebox maze and watch the plant work though the obstacle course, searching for sun.
