Rayleigh Scattering Animation (why the sky is blue)

This is just a mock up, it was never used in a presentation.

We were trying to explain scattering in a physical way that makes sense to kids, but also addresses the 1/λ4 wavelength dependence. I want to make clear that I mean blue light is scattering much much more than red, the photon does not partially scatter and continue to move in the same direction. Also, we have already addressed the reason the sky isn't perceived as violet which is why it isn't included. Mie scattering is another video, and perhaps a discussion of light incident could help explain the colors we see at different times of the day. Overall, the physics of light are pretty complex and cool. Maybe we'll do an animation on thin film interference.
