8th Grade Earth Science

Natural systems undergo change.

2. Some changes in the earth's surface are abrupt (such as earthquakes and volcanic eruptions) while other changes happen very slowly (such as uplift and wearing down of mountains). (AKSci - A.7)

Examples of What Students Should Be Able to Do:

• Conduct a laboratory investigation to demonstrate how constructive and destructive forces can cause changes on the earth's surface. Explain the process(es) involved.
