This page is a comprehensive module for grades 8-12 on the origin of colors in materials, including liquids, solids, and gases. "Color in gases" includes experiments that explore the color of fireworks, the origin of smog, the cause of rainbows, and why the sky is blue. The "Color in liquids" section includes investigations into why plants are green, the color change of acid/base indicators, why objects change color when they rust, and how glowsticks and fireflies produce colored light. The section dealing with "Color in solids" examines how colors are produced by the interference of light using an audio CD, how UV light can be detected using fluorescence, and how light emitting diodes work.
This resource is aligned with national science education standards and has been refined through classroom testing.
This item is part of a larger collection of inquiry-based modules. SEE RELATED ITEMS on this page for a link to these materials.
This resource is part of a Physics Front Topical Unit.
Topic: Nature and Behavior of Light
Unit Title: Visible Light and Color
For students who have explored the basics of color mixing, this is an excellent unit to continue their investigation into the subject. This comprehensive module (same authors as the module above) takes students on a hands-on journey of the origin of colors in solids, liquids, and gases. They will explore the color of fireworks, why the sky is blue, how glowsticks and fireflies produce phosphorescent light, and how LED's work.Link to Unit:
