Modeling the Earth

The basic idea of my model lesson is that I used a large Earth ball to model how the movement of the Earth affects life on Earth. We talked about tilt, rotation, and revolution.  The hardest part was that this was suposed to be a review for the students and I found they didn't remember many of the things that we had already talked about.  I was happy to see that after this activity they were able to fill out a concept map about the different movements and connect them to the coresponding affects.  I think that it worked even better because the students were actually parts of the model and moving the Earth themselves.
