This 5E lesson plan (engage, explore, explain, elaborate, evaluate) is hands-on and designed to get students actively involved. This lesson builds upon itself from the very beginning. Students first explore models of the earth before beginning an in-depth study of earth's layers. Once students note similarities and differences between the models of the earth and earth, students will explore the properties of each layer including a very fun, hands-on solid/liquid that represents the mantle. From oral communication skills to written skills and working in cooperative learning groups to individual evaluation, this lesson plan is designed to actively involve each of your students!
