Students use a simple model to discover that air moving over water causes the surface of the water
to move horizontally. In writing and in a discussion, students relate this concept to surface currents in
the ocean and the Great Lakes.
Objectives:
- Relate the motion of surface currents (cause) to the motion of objects floating in the ocean and Great Lakes (effect)
- Relate the transfer of energy from wind moving across water (cause) to the horizontal movement of water (effect)
- Use the term “surface current” to explain horizontal movement of surface water caused by wind
- Explain that surface currents affect surface water, not deep water
