What are some ideas for an oceanography lesson plan for younger elementrary children?

Question

I am planning an eight week summer camp overseas that will introduce the basics of marine biology, the ocean, and various topics that relate. I am not so well versed in this but have taken a global environment class that spent a month discussing the sea and other topics.

What are some interesting sub-topics, experiments, activities, lessons I could design for the kids?

Any good ideas are welcome. Thank you!

Answer 1

I have an entire unit on oceanography.  I had to do one for my college class last semester.  Do you need like tests and things also?
