Create 3D glasses and use them to explore color, light and optics. Fool your brain into 'seeing' three dimensions on a flat surface!

Learners place multiple M&M's in a plate of water to watch what happens as the candies dissolve.

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 activity, learners "draw" with frozen tempera paint. The ice cubes are prepared the day before by placing watered down tempera paint and popsicle sticks in ice cube trays.

It's difficult to see convection currents in any liquid that's undergoing a temperature change, but in this Exploratorium Science Snack, you can see the currents with the help of food coloring.

In this optics activity, learners conduct an experiment to explore peripheral vision. Learners collect data about their ability to see shapes, colors, or letters using their peripheral vision.

In this activity, learners observe mixtures of sand samples glued to note cards, and consider how sand can differ in size, shape, and color, and where it comes from.

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 (16th on the page), learners play a variation of the "I Spy" game to explore color. Learners work in teams with each team assigned a color.

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

How many colors make black? Gather as many water soluble black markers as you can find.

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

In this activity, learners explore light, color and rainbows by making their own rainbow glasses.

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.
