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

This is a quick activity (on page 2 of the PDF under Stained Glass Activity) about the "Tyndall effect," the scattering of visible light when it hits very small dispersed particles.

In this activity about light and perception, learners create pictures in thin air.

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

With a laser pointer and some household items, learners can create their own laser light show. They can explore diffuse reflection, refraction and diffraction.

In this optics activity, learners use everyday materials to make a color wheel. When learners spin the wheel like a top, they will be surprised to see all the colors mixing together to appear white.

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.

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

By making models of light waves with paper, learners can understand why different colors appear in bubbles.

This fun activity uses simple materials such as milk cartons and mirrors to introduce the ideas of optics and visual perception.

In this math activity related to light, learners explore why a light, such as a candle or a streetlight, looks dimmer the farther away from it we get.

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

In this activity, learners explore color, light and shadow by creating their own puppets to hold in front of a light source.

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 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!
