Center Focus

Round vs. Flat

  1. Your students should be familiar with the argument of the Earth being round versus flat before presenting this center.
  2. 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.
  3. 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.

  4. When everyone has visited this center you should combine all of their responses into a class book entitled Round vs. Flat.
