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 activity about light and refraction, learners make a lens and magnifying glass by filling a bowl with water.

In this optics activity, learners experiment with polarizers (small dark rectangles) to examine light intensity.

In this optics activity, learners split white light into all its component colors using three household items: a compact disc, dishwashing liquid, and a hose (outside).

This is an activity about the behavior of light. Using simple, everyday objects, learners will discover that light moves in straight lines until acted upon by another object.

In this activity, learners work in groups of four to explore light. Learners create new colors from the primary colors of light from flashlights covered in theatrical gels or cellophane.

In this activity, learners use their strength to light a light bulb. A chain made from paper clips is placed in series with a battery and flashlight bulb.

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!

In this activity, learners make prisms from gelatin. Learners then shine light through the prisms and discover what happens. This activity introduces learners to the idea of refraction.

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

Learners observe different paper samples under ordinary room light and under a black light to learn some of the chemical differences between different types of paper.

Have fun with additive mixing! Observe what happens when the three primary colors of light--red, green and blue--are mixed together, resulting in white light.

In this activity, learners use transparent tape and polarizing material to create and project beautifully colored patterns reminiscent of abstract or geometric stained glass windows--no glass required

In this activity, learners overlap the three primary colors to see how all other colors are made.

In this activity, learners use an old CD to construct a spectroscope, a device that separates light into its component colors.

In this activity, learners use their imaginations and picture a scene in their heads.

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

In this activity about light, learners explore how water can refract light and change the way they see things.

Learners examine the properties of light by experimenting with an LED-flashlight and polarizing filters. When two polarizers are used, they block all light when they are placed at right angles.

In this fun optics activity, learners explore principles of light, reflection (mirrors), and perception. Learners work in pairs and sit on opposite sides of a "two-way" mirror.
