Summary: This week in class we learned about land formations. A land formation is something that was created due to a change in the land. An example of a land form would be a mountain, which was caused by two plates crashing into each other, and both rising up. Islands are also land forms, as they are made when plates diverge and become underwater volcanoes, which then erupt and cool into a island.

SP2: Developing and using models
This week in class we had begun building models of certain land forms and show how they were created. We will use these models to provide evidence that the how the land on the Earth moves can create these land forms and how the Earth looks very much different from how it did millions of years ago.

Plate Tectonics 03/16

Summary: This week in class we learned about the different ways that plates move. There are four different ways that plates move. Subduction, when one plate goes under another, it can result in above ground volcanic activity. Divergent plate movements are when a plate moves away from itself, which causes underground volcanic activity. Transform boundaries are when plate move so that they brush against each other, like their slipping and sliding. Collisional boundaries are when plates crash into each other creating things like mountains.

SP2: Developing and using models
This week in class we used a gizmo online model to see how each of the plates move in different ways. It was hard to see how the transform boundary moved at first but we finally figured it out. We then used our knowledge gained from the Gizmo model to fill out a worksheet that the teacher had made for us. It was really helpful.

Layers of the Earth 03/09

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.
