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 outdoor, nighttime activity, learners gather around a brightly lit, white surface and study the behavior of nocturnal animals attracted to the light, particularly night fliers.

In this optics activity, learners use a shoebox, colored cellophane and sunlight to "change" the colors of gumballs. Learners will be surprised when the green and blue gumballs appear black!

Did you know that using a lens one can bend light to make pictures of the world? It's true!

With little more than a flashlight, a straw, and a plastic lid, make an observatory so you can see the amazing colors in bubbles.

In this activity, learners use tonic water to detect ultraviolet (UV) light from the Sun and explore the concept of fluorescence.

Learners mix a solution of luminol with hydrogen peroxide to produce a reaction that gives off blue light.

Learners observe glow-in-the-dark objects in a homemade light-proof box. Objects can include glow sticks, glow-in-the-dark toys, and toys with fluorescent paint.

In this activity, learners investigate the reflective properties of light and mirrors as they make a kaleidoscope.

In this sunny day activity, learners compare how a cup of water and a cup of tonic water reflect or refract light in the sun.

In this activity, learners will explore light and rainbows with this easy setup! Learners will only need a cup of water, some paper and a flashlight.

In this activity, learners explore light and shadows by creating a lantern they can keep on their nightstand.

In this activity, learners will explore how different colors of lights interact with objects around them. Will a blue object stay blue with a red filter?

In this activity, young learners will explore light and darkness through flashlight play.

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.

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

In this activity, learners use simple materials to create giant bubbles.

In this activity on page 7 of the PDF (Plants—The Green Machines), learners examine the effects that light and air have on green plants.

In this activity, learners build a simple pinhole viewer. They use this apparatus to project images from a variety of light sources, including a candle, the Sun, and the Moon.

In this hands-on activity, learners build their own kaleidoscopes and explore how light can reflect of off surfaces such as mirrors, to produce beautiful patterns.
