 Color Sines Classroom Activity In this lesson from Math Machines, the class will use an RGB Color Mixer and a graphing calculator to control the color of a single pixel. In addition to learning about color, the students will gain experience using and programming calculators. A participant handout (including worksheet) and facilitator notes are made available for download in DOC file format. A link to a required calculator... http://www.mathmachines.net/Activities/colorsines/index.htm
 Calculation Investigation This activity demonstrates how white light, such as that from an overhead projector, is broken up into its component colors by a diffraction grating. Students will learn the relationships between light's wavelength, frequency, and energy and how to convert between any of these characterizations of a particular color of light. They will understand that light can be described in many ways, (energy,... http://imagine.gsfc.nasa.gov/educators/lessons/xray_spectra/...
 What Is the Frequency, Roy G. Biv? This lesson is based on the concepts of frequency and wavelength, how they relate to each other, and how they correlate with the colors of the visible spectrum. The students will examine these concepts through a hands-on lab that involves measuring and timing wavelengths by pulling adding machine tape through a simple, student-made apparatus. This lab is followed up with critical thinking and... http://imagine.gsfc.nasa.gov/educators/lessons/roygbiv/
