Round vs. Flat
- Your students should be familiar with the argument of the Earth being round versus flat before presenting this center.
- You will want to provide research materials as well as instruments that will encourage them to really consider this "problem." These instruments should include a globe, star charts, pictures of the horizon, etc.
- Have your kids use these materials and their prior knowledge to answer the following question:
Why can Earth not be flat? Explain your reasoning. Use diagrams as necessary.
- When everyone has visited this center you should combine all of their responses into a class book entitled Round vs. Flat.
