This is a simple and fun activity for learners to explore water and colors.

In this activity, learners create a simple “top” from a CD, marble and bottle cap, and use it as a spinning platform for a variety of illusion-generating patterns.

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.

Young learners investigate and observe the properties of three liquids -- water, vegetable oil, and corn syrup. They use their senses to collect data and ask and answer questions.

This is a quick activity (on page 2 of the PDF under Butterfly Wings Activity) that illustrates how nanoscale structures, so small they're practically invisible, can produce visible/colorful effects.

In this activity, learners use simple materials to create giant bubbles.

In this activity, learners explore acid and bases as they create their own invisible ink out of baking soda and grape juice.

In this activity, learners examine how colored lenses act like filters and absorb all colors of light except for the color of the lenses.

In this activity, learners explore liquid crystals, light and temperature. Using a postcard made of temperature-sensitive liquid crystal material, learners monitor temperature changes.

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

Learners observe different light sources, outdoors and indoors, using prism glasses (diffraction glasses) and color filters.

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 activity, learners use transparent tape and polarizing material to create and project beautifully colored patterns reminiscent of abstract or geometric stained glass windows--no glass required

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

Learners analyze candy-coated sweets using chromatography. Learners use this method to separate the various dyes used to make colored candy.

In this activity, learners will experiment with changing flower colors. Learners will investigate the effects of acids and bases on flower colors.

In this activity (p.5-6 of PDF), learners investigate natural selection. Learners discover that natural selection, which takes place over decades, can lead to altered populations within a species.

In this activity, learners overlap the three primary colors to see how all other colors are made.

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.
