Journey to the Center of the Earth

This week in science, we studied the structure of the earth. M and BJ made playdough replicas of the earth, showing each layer: inner core, outercore, lower mantle, upper mantle, and crust. Did you know the center of the earth is made of solid iron?

E and Z made their models of earth using paper.
Did you know the earth's crust is 6 miles thick?
