What is the earth like inside?

Is the earth all magma or is it solid just like a giant rock inside? Mrs. Rathor's 9th Grade Inter-coordinated Science students answered these questions and more in their Plate Tectonic Egg Lab.  In the lab, students used the eggs to illustrate the layers (crust, mantle, and core) of the Earth. Mrs. Rathor's is focused on making science relevant to students by providing them with the opportunities to create physical models of the science standards that they are studying their text.
