Stability and Change


Students know:
  • Wind and water can change the shape of the land on Earth, sometimes slowly and sometimes quickly.
  • Solutions that can slow or prevent wind or water from changing the land impacts the natural world.


Students are able to:
  • Examine changes caused by Earth's events, like winds and floods.
  • Test, compare, and evaluate solutions (technologies) that address changes caused by Earth's events.


Students understand that:
  • Earth's events may change the land slowly or rapidly.
  • Developing and using technology has an impact on the natural world.
