1. Expose students to the Digital Atlas of Idaho. Background information obtained in the geology sections would be useful in introducing the basic composition of the earth.
2. Teachers may want to do this activity when talking about earthquakes. The outer layer of the ball would represent the outer crust of the earth. Teachers can discuss the movement of the outer crust and how it relates to continental drift.
3. Each student will receive a Styrofoam ball with a wedge that has been cut out.
4. Students will color and label the different layers of the earth with watercolors or with crayons. Students can glue paper cutouts of the continents on the surface. If desired, teachers can have students also trace the major land plates on the surface of the earth.
5. Summarize what these Styrofoam models represent.
