Earth's Structure and Plate Tectonics
 * __Unit Title__**

__**Unit Summary**__ This unit is designed to help the students demonstrate an understanding of the materials that makeup the structure of Earth and the processes that have altered this structure. The fist goal for the students is to summarize the major points about the Earth's layers. Then, they will denomstrate an understanding of how that structure has driven the changes the Earth has experienced over geologic time. Since the unit is guided by the content, unit, and essential questions, all the activities are designed to help the students understand and answer the questions that are used at the beginning, middle and end of this unit. For example, the students will perform a lab using a milky way candy bar. This candy bar has three layers in much the same order as our own Earth. They will realize that the interactions among and between these layers cause the changes and movements that the Earth has sustained and will sustain (namely that the Earth is broken into large plates, these plates move, and this movement creates some natural features and events that we experience here on Earth).

 * __Grade Level__**

__Essential Question__ How might the structure of the Earth change in the future? How has the Earth's specific layers and compostion accounted for the geologic changes on Earth? How has the theory of plate tectonics accouted for the motion of the litospheric plates? How has the theory of plate tectonics accouted for the geologic activities at the plate boundaries? How has the theory of plate tectonics accouted for the change in landform areas over geologic time?
 * __Unit Questions__**

What are the Earth's layers? What are the specific conditions and composition of the crust, mantle and core? In what oder are the layers found? What is the crust and top of mantle called? What is the less dense layer? What density does the mantle have? What is the most dense layer? What do we call the crust that makes up the land that we live on and what is it made of? What do we call the crust under the oceans and what is it primarily made of? What is the top portion of the mantle called? What two layers make the core? What is the theory of plate tectonics? How do lithospheric plates move? What are lithospheric plates? What is the hypthosis of continental drift? Who developed this hypothesis? What evidence was used to support the idea of continental drift? What are the different types of plate boundaries and how do they move? How does the movement of the plates change landforms over geologic time? What are convection currents? How do these currents affect Earth?

This is my example of the student ppt project.

This is a checklist they will use to keep them on track.

This is how the students are going to be graded on the project (summative)

This is a support document to help the students get the right info on the right slide. It also tells who in the group is responsible for which slide.

This is my preassessment.

Please provide feedback by posting the comments to this wiki page. I would love to have uploaded all of my activities to this wiki, but the teacher home directory link has been taken off the portal page. I have no way to access all of my files I save on my desktop at school.
