Understand
Students will explore the nature of sound and electromagnetic radiation in order to understand that the parts and interactions of waves determine color and what is visible.
Do
Create a picture/poster to supplement notes that diagrams and describes the EM Spectrum giving the name, range of wavelength, and to scale diagram of each type of wave.
Manipulate wavelength, frequency, and amplitude of waves on internet sites to predict and observe what happens to the color and type of wave. (include sound and amplitude to bring in prior knowledge).
Make a flow map diagramming the path light takes through the eye to see objects and color.
Diagram the parts of the eye.
