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.

In this activity, learners explore why they can see colors in bubbles and why they change.

In this optics activity, learners examine how a transparent material such as glass or water can actually reflect light better than any mirror.

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.

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 "Sid the Science Kid" activity, learners set up a simple experiment to find out how sunscreen counteracts the effects of the sun.

This activity guide features three related explorations to help learners ages 3-6 investigate shadows via the following science concepts: A shadow is made when an object blocks the light; you can chan

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 explore how light bends and affects what we see.

Learners use two mirrors to explore how images of images of images can repeat forever.

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.

This activity provides an opportunity for learners to observe and examine how carbon dioxide, water, and light produce glucose/starch through a process called photosynthesis.

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