This Photon Folks lesson plan also includes:
Pairs of physical science pupils play with a beach ball that portrays a particle of light. One partner is the source of photons, and the other is the atmosphere as light strikes it. Three things can happen: the photon (beach ball) is absorbed, transmitted, or reflected. This activity is brief, but befitting. Background information is provided. If time is short, consider this as a demonstration rather than a participatory activity, because there is sure to be some playing around!
