"Exploring the Universe: Filtered Light" demonstrates how scientists can use telescopes and other tools to capture and filter different energies of light to study the universe.

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

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

In this optics activity, learners make a lens and explore how the eye manipulates the light that enters it.

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

In this optics activity, learners explore color by examining color dots through colored water and the light of a flashlight.

In this optics activity, learners create a ripple tank from household materials to study waves. Learners build the tank and then explore by making various types of waves.

In this activity, learners will explore how light can refract or break apart into different colors.

In this activity, learners use a flashlight, a glass of water, and some milk to examine why the sky is blue and sunsets are red.

This activity generates learner excitement about light through the creation of a room-sized rainbow.

In this activity related to light and perception, learners use a pinhole in an index card as a magnifying glass to help their eye focus on a nearby object.

This activity (aka "snack") provides instructions for discovering your blind spot. It is an exploration of light and visual perception using simple materials you may have around the house.

In this optics activity, learners explore how many objects they can see in a set of mirrors (hinged like a book) at various angles.

In this activity, learners experiment with shadows and light sources to understand the relationship between the angle illumination and the shadow's length.

This is a quick activity/demonstration that introduces learners to the concept of index of refraction. Learners place stirring rods in a jar of water and notice they can see them clearly.

In this activity, learners will see how UV light affects colors over time by making their own sunprint on construction paper.

Align four color transparencies, each one a single color (cyan, magenta, yellow, and black), and see a beautiful full color image.

In this activity (1st on the page), learners find their blind spot--the area on the retina without receptors that respond to light.

Make a kite out of a garbage bag, shower curtain, painting tarp--anything light, thin, flexible and plastic!
