In this activity, learners actually feel the difference in energy required to light two different types of light bulbs: incandescent light and LEDs.

In this three-part activity, learners conduct simple experiments to see how light refracts and reflects, and how colors of light affect what we see.

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).

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 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.

This simple hands-on activity demonstrates why the sky appears blue on a sunny day and red during sunrise and sunset.

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.

This is an online exhibit about color perception. Learners set a random background color and then try to mix red, blue, and green light to match.

In this optics activity, learners explore how they can make gelatin stop light, but not stop them from seeing fruit suspended within.

In this activity, learners explore phosphorescence and how certain materials can absorb and store energy from a light source.

In this activity (posted on March 12, 2011), learners follow the steps to construct a spectroscope, a tool used to analyze light and color.

In this four-part activity, learners explore light and sound through a variety of hands-on investigations.

In this optics activity, learners explore how light bends and affects what we see.

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 four-part activity, learners will discover the exciting world of light--the most important form of energy in our world--and be able to identify and describe different types of light.

This activity (located on page 3 of the PDF under GPS: Light and Color Activity) is a full inquiry investigation into mixing colors with light.

In this activity, learners use gelatin as a lens to investigate the properties of laser light.

In this optics activity, learners make a "light fountain" from a clear plastic bottle, flashlight, and other simple materials.
