This unit was originally created to go along with the books Sharks: Challengers of the Deep by: Mary Cerullo, but over the years I have added to it and extended the project to make it an interdisciplinary unit. I have learning targerts, KWLW pre, during, and after reading graphic organizer. I have project choices. Shark vocabulary and illustrations. I usually start this unit off with a clip from Shark Week from the Discovery Channel and that gets things going! Great nonfiction unit that can be adapted and differentiated for many levels.
