Reef Fish Identification: Florida, Caribbean, Bahamas is the main text that my seventh graders are using in one of my classes right now. This field guide has been essential in our Field Trip Series class, where our seventh graders learn about marine ecology, as well as how to snorkel. Yes, one of my classes is weekly snorkeling lessons in The Bahamas with hilarious ten year olds. Don't hate!
This reference book is used by serious divers and fish lovers; it is also an amazing way to teach students more about nonfiction reading and how to use scientific texts. We've covered everything from using the table of contents, how to identify fish that one has spotted, and how to organize nonfiction writing to provide information. It is on the expensive side, but is really invaluable in teaching our students about the amazing place that they live.
