EarthRef.org Digital Archive (ERDA) -- A Week of Science at Sea: Day 4: Animal diversity: So many fish in the sea!

Description
This lesson introduces students to the diversity of life in the oceans, using images of samples taken during an oceanographic cruise, and gives an introduction to the taxonomic system used to classify those organisms.
This is the fourth lesson in a series of five lessons with accompanying videos, collectively entitled "A Week at Sea Aboard the Research Vessel Melville." The video for today is called "Animal diversity" and can be found on YouTube at this link http://calechoes.wordpress.com/video/. This video is most appropriate, but not required, if watched before beginning the exercise, as it introduces the methods of collecting fish and other animals at sea, and some of the researchers involved in collecting samples on this cruise. Following the video, which is 11 minutes long, solicit student questions, and then show the Powerpoint, and then, if there is time, introduce the basic taxonomic exercise described below.
