Using C-Spectra (a diffraction grating alternative), students were able to gather evidence to see that white light is comprised of many colors, which are identified as red, orange, yellow, green, blue, indigo and violet. From there, students connected their ideas to the light model for how we see. In order to see something that's yellow, yellow light must reflect into our eyes. But what happens to all the other colors?
Check out some students' work who continued to revise their models for how we see. Great work 6th grade!
