4 week unit
1. Students should begin to visualize how the
interior of the Earth looks like in three dimensions.
2. Students should be able to construct a three
dimensional model of either a shield, composite, or cinder volcano.
3. Students should be able to understand that the
structure of various volcanoes relates to how it has erupted through
4. Students should begin to understand how
earthquakes are measured by either the Mercalli or Richter scale.
5. Students should think about how different
structures react during an earthquake.
6. Students should start understanding that
earthquakes and volcanoes provide data for interpreting how the Earth's
outer surface moves.
7. Students should be able to distinguish the layers
of the Earth.
8. Students should realize the outer features of the
Earth provide clues of that is going on inside the Earth.
9. Students should understand that the intensity of
an earthquake determines the damage.
10. Students should begin to understand that
building structures can be engineered to withstand shaking.
