About This Lesson
As we saw in the last segment, the earth’s poles are cold and the equator is warm. So, if heat moves from warm spots to cold spots, why doesn’t the earth’s heat just move from the equator out to the poles? Basically, because the earth isn’t exactly sitting still — it’s rotating at a high speed! Let’s demonstrate what happens with a spinner, some paper and food coloring. Make a prediction: what will happen to the colors? How dramatic of an effect do you think you will see? Tags: Little Shop of Physics, Colorado State University, Brian Jones, Physics, K-12
