Like water drops in falling rain, a CD separates white light into all the colors that make it up.

Learners demonstrate how water can distort, refract and magnify light.

In this activity, learners create a cylindrical mirror to see themselves as others see them.

This is a great activity about wave interference. Learners will create their own wave machine and discover wave properties through hands-on investigation.

In this activity, learners build inexpensive kaleidoscopes using transparency paper and foil (instead of mirrors).

In this math-based activity, learners model the intensity of light at various distances from a light source, and understand how astronomers measure the amount of sunlight that hits our planet and othe

This activity provides instructions for building a mirrored tube--a smaller and simpler version of a submarine's periscope--that lets you see around corners and over walls.

In this trick, hold your hand over a burning candle without getting burned, by reflecting and transmitting the light of two candles. This activity is best suited as a demonstration.

In this activity, learners explore liquid crystals, light and temperature. Using a postcard made of temperature-sensitive liquid crystal material, learners monitor temperature changes.

In this activity, learners explore how pictures change in curved mirrors. Learners make cylindrical mirrors by wrapping Mylar around soda cans.

In this activity, learners explore how light and dark colored objects absorb the Sun's radiations at different rates.

In this activity, learners use a compact disc to make a spectrometer, an instrument used to measure properties of light.

In this activity, learners will explore light with reflective surfaces. Learners will make predictions and share their observations as they experiment with directing a beam of light.

In this two-part activity, learners explore the properties of liquid crystals, which are responsible for why mood rings change color.

In this activity, learners explore how mirrors reflect light and change the way we see things.

In this activity, learners explore how polarizing sunglasses can help diminish road glare.

In this activity, learners make optical fibers out of strips of gelatin.

In this activity, learners trap a thin layer of air between two pieces of Plexiglas to produce rainbow-colored interference patterns.

In this activity (page 1 of the PDF under SciGirls Activity: Horse Ears), learners observe how an animal responds to its own reflection.

In this activity, learners use the Sun's energy to cook marshmallows. Learners construct the solar oven out of simple everyday materials.
