New from No More Boring Science - The core of the sun is a ball of superheated plasma that produces millions of watts of energy. Some of this energy is in the form of light. But, that light just doesn't stream to the surface, flying across space to shine down on us. No, things are more fascinating and complicated. It takes, on average, 16 million years for a photon of light to escape the sun and shine on us. Why? The Random Walk.
This lab helps model the random motion of photons of light as they bounce back and forth in the radiative zone of the sun. This lab allows students to see exactly how this random motion works, and makes them plot just how random the motion can be. Included extensions also quantify the activity, allowing this lab to scale from middle school science all the way into college astronomy.
