Season/Energy Activity Part II
He took us outside and covered up the solar panels. He made a big deal of finding the most direct source of light from the sun and tilting the globe so that the equator was getting the most direct light. He released his hands from both locations and the fan at the equator was going full tilt but the one at the pole was going very slow (because it was getting less light).
This was a great demonstration of how certain parts of the earth receive more or less of the suns energy at different times of the year (causing our seasons).
