Color Vision
Make a whole rainbow by mixing red, green, and blue light. Change the wavelength of a monochromatic beam or filter white light. View the light as a solid beam, or see the individual photons.
We had a TON of questions that we came up with to explore light and color! So we used an online simulator that could change bulb and filter color, as well as easily manipulate three lights at once to varying degrees! We discovered why the color white appears, why black appears, why grey appears...and well, pretty much everything in between!
