Earth's Layers: Foldable

To learn about the Earth's layers, students created foldables.  To create these, students colored the four layers of the Earth (crust, mantle, inner core and outer core), and labeled them.  After learning about what the composition and states of matter were in each layer, students answered two questions: 1) How does matter move in this layer? and 2) What physical mechanisms cause this?  I helped them with the inner core, and the students determined the rest of the answers in groups.
