Summary: This week in class we learned about the layers of the earth. There are 4 layers in the earth: The Crust, The Mantle, The Outer Core, and The Inner Core. The Crust is the thinnest layer of the Earth and the one you are standing on. The Mantle is the thickest layer of the earth and it is made up of semi-solid rocks. The Outer core is the third layer of the Earth and is the only layer made out of liquid. The Inner Core is the inmost part of the Earth and the pressure is so great there that it is a solid ball.

SP2: Developing and using models
This week in class we developed a model of all the layers of the earth. We cut out parts of an image that represents a layer of the Earth. we then glued fact about the layer next to it on a foldable. After that we glued labels on to each layer of the Earth. We will use the model to help us remember about the layers of the Earth when we need to use them.
