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

In this activity, learners explore what happens when polarized white light passes through a sugar solution.

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

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

Learners apply their knowledge from a previous study to identify different liquids--water, corn syrup, and vegetable oil.

Learners are challenged to discover the relative densities of colored liquids to create a rainbow pattern in a test tube.

In this fun, hands-on autumn activity, learners experiment to discover whether the colored substances in leaves can be separated from the leaves.

In this activity, learners will discover what colors are in different markers, and may be surprised at the results.

In this activity (posted on March 12, 2011), learners follow the steps to construct a spectroscope, a tool used to analyze light and color.

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 will experiment with changing flower colors. Learners will investigate the effects of acids and bases on flower colors.

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 "Chemistry is Colorful" learners explore different materials through paper chromatography.

"Nature of Dye" allows participants to create their own dyes and art while exploring how chemicals interact and how these interactions can have real-world applications.

In this challenge, learners have to figure out in what order to combine five solutions to change the color from clear, to yellow, to blue, and back to clear.

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

In this two-part activity about luminescence, learners explore the chemistry that happens inside glow sticks and other light producing reactions.

In this activity, learners add dilute bleach solution to water that has been dyed with yellow, blue, and green food color.

In this chemistry challenge, learners systematically investigate which combination of four solutions produces a deep red color.

Learn about dyes and mordants (fixatives) when you tie-dye fabric with Kool-Aid™ and vinegar. The colored molecules in Kool-Aid™ form a chemical bond between the fiber and dye molecules.
