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.

In this science fair project, we'll explore how blocking the sun's light can stop those can stop photosensitive paper from changing color.

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.

Water, along with soil and light, is a necessary component for plant growth. So what's better for promoting plant growth: tap water, or rain water?

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.

Glass is see-through, but usually you can still see that it is there. In this experiment, we use baby oil to make glass go completely invisible.

Deck the halls with last season's Christmas lights for a spectacular and electrifying science activity.
