In this experiment, learners work in teams to investigate how the color of a surface influences its ability to reflect light and therefore heat.

In this lab (Activity #1 on page), learners explore how we see color.

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.

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

In this activity, learners explore how light and dark colored objects absorb the Sun's radiations at different rates.

In this activity (page 3 of the PDF), learners will observe a physical change.

Learners add different liquids (water, salt water, alcohol, and detergent solution) to water and observe the different ways the different liquids combine with water.

Learners use chromatography to separate and analyze the mixture of pigments in leaves. Use this activity to discuss photosynthesis as well as why leaves change color in autumn.
