Here's  short video by the National Oceanic and Atmospheric Administration (NOAA) gives a good introduction to waves.

By the end of this video, you should be able to answer the following:

  •  How are ocean waves formed? 
  •  How does wind make waves?
  •  As the wind energy moves through the water, which direction does the water move? 
  •  How is the wind energy transferred from one water molecule to another? 

Wave and Tidal Energy  this document will help if things are unclear

How does a direct current (DC) generator work, and what is the difference between a DC generator and a DC motor?

Do Internet research on how DC generators work, how they differ from DC motors and alternators, then investigate actual DC generators

All students should bring in a plastic water bottle next week ( Sept. 18-20), we will build impellers and see how much power we can generate using a multi meter.
