What words did you use in your warm-up from your word-bank?

Poll

Take 5 minutes to complete the 'A New Message from Dr. Moraga activity' in schoology.

• Finished!

• Not done yet!

Multiple Select

What are some examples of soft solids?

• Butter

• Brick

• Jello

• Wood

Considering the mantle

• We know that Earth's outer layer is made of hard, solid rock divided into plates, and we know those plates move. But how?

• Below the outer layer is the mantle. In this activity, you will use the Sim to investigate how the composition of the mantle might allow the plates to move.

• Open the Sim, leave this screen open.

• 1) Select Region 1 from the Globe View. 2) Adjust the mantle setting to Hard Solid. 3) Press RUN and observe the motion of the plates.

What did you observe when the mantle was set to hard, solid rock?

Considering the mantle

• Once the run has ended, press BUILD.

• Adjust the mantle setting to Soft Solid.

• Press RUN and observe the motion of the plates.
