If you want student engagement then the SMART Board Presentation is the way to go. My students are much more interested and love to participate when I use the SMART Board. Make sure you download a copy of the FREE cornell notes for this presentation. This SMART Board Presentation covers the BASICS of Visible Light and Color. It covers transparent, translucent, and opaque objects. This presentation also addresses what happens to colors (wavelengths) when they are reflected off of an opaque object and includes the differences between pigments and light. This presentation addresses California State 7th Grade Science Standard 6E - Students know that white light is a mixture of many wavelengths (colors) and that retinal cells react differently to different wavelengths and California State 7th Grade Science Standard 6F - Students know light can be reflected, refracted, transmitted, and absorbed by matter.
