Students Make Layers of the Earth With Modeling Clay

Our class learned about the depth of each of the layers of the Earth last week.  We made the layers with modeling clay.  Each layer was to depict the size it is compared to the sizes of the other layers.  Students placed the inner core in the center, then the outer core, mantle, and crust.  The crust showed the oceans/lakes/ponds/rivers that make up 3/4 of the surface of the Earth plus the seven continents that make up the other 1/4.
