The Color Spectrum

Description

The lesson introduces the idea of where color comes from by looking at the color spectrum. The students brainstorm where they think color comes from with visuals that lead them to the rainbow. Next we discuss the science of the color wavelengths and why we see the rainbow in its natural order. The second activity includes each student experimenting with a prizm and refracting the light to make the spectrum right in our classroom. The final product is a painting or Roy G Biv and a rainbow!
