We feel the wind everyday. The air is almost always in motion. One day it may be from the north and the next day from the south. There are many sources for wind: mechanical sources such as fans and, in nature, falling rain as it drags air along. But what is the origin of wind on the earth? Using a toaster, the students will observe that wind is created by the heat that rises.
