The dogs I know like to be walked at least twice a day -- once in the morning, and once in the evening. But even though I'm the same person and it's the same dog in the morning and evening, our shadows change... In the morning, our shadows point in one direction. This is true regardless of which way we are facing. The shadows of trees, buildings, cars, fire hydrants, and blades of grass all point in the same direction as ours. In the evening, our shadows all point in approximately the opposite direction.

This lesson attempts to correct the common misconception that the Earth is closer to the Sun during the summer in the Northern Hemisphere. Sometimes, in order to correct science misconceptions, it is necessary to confront them head on. This lesson encourages students to voice this misconception at the beginning of the lesson and then attempts to correct it first, by exploring the reason for it, and then by presenting an alternate explanation.
