Our Ocean Planet: A Teacher's Manual for Ocean Science -- Free!

The Central Caribbean Marine Institute makes the teacher's manual vailable online at no charge:

This teacher’s manual is intended to be a reference tool for Cayman Island teachers. In addition, we hope that the activities at the end of each section will provide Cayman Island children with a fun and enlightening glimpse into how important the sea around us is to our daily lives.

Though targetted to children in the Caymans, it would surely be an asset for any teacher anyplace in the world.
