Sun and Earth Screen Cast

This is the screen cast that I showed to a group of second graders in my school (pretend lesson).

Susie Smith - why we have seasons

We have seasons because the earth goes around the Earth. The sun hits part of the Earth. That makes summer. The sun does not hit some parts as well. That makes winter.

Johnny Jones' - Sun and Earth

The Earth goes around the sun in one year. That what makes seasons.
