- Reading:
Lesson 2 of the Light and Color Chapter of the Tutorial are perfect accompaniments to this Interactive. The following pages will be particularly useful in the early stages of the learning cycle on light and color:
The Electromnagnetic and Visible Spectrum
Visible Light and the Eye's Response
Light Absorbtion, Reflection, and Transmission
Color Addition
Color Subtraction
- Minds On Physics Internet Modules:
The Minds On Physics Internet Modules include a collection of interactive questioning modules that help learners assess their understanding of physics concepts and solidify those understandings by answering questions that require higher-order thinking. Assignments LC6, LC7, and LC8 of the Light and Color module provides a great complement to this Interactive. It is best used in the middle to later stages of the learning cycle. It would be a great follow-up to the use of this Interactive. Visit the Minds On Physics Internet Modules.
