Aquatic Ecosystems

This exercise is a combination of a RAFT and jigsaw!

R-Role: science expert A-Audience: classmates F-Format: PowerPoint or Prezi T-Topic:______

Jigsaw: you will be teaching your classmates about your designated topic! Ya’ll will put together everyone’s lesson to develop the entire chapter!

Rules for your lesson: 1. Must provide an outline for classmates to take notes 2. Must enable classmates to answer all questions at the end of the chapter pertaining to your topics 3. Must include all highlighted terms/key terms 4. Must include pictures 5. Must include cool/interesting facts or species NOT found in your textbook 6. A visual Model NOT included in PowerPoint/Prezi (poster, model, etc-involving the audience is always a good choice)

Directions: You will develop a power point presentation (or other means of presentation approved by me) concerning your assigned topic. I have provided a basic outline of your material as an example. Remember, you are taking on the role as expert scientist, so you need to perform a great deal of research. Be sure to be as detailed and as interesting as possible. Your group will receive two major grades: one on (1) content and another on (2) presentation. You will be given daily grades for progression. Make sure you include all of the 5 rules mentioned above and well as all of the points in the outline I made for you.

Also, we will participate in DEBATES concerning which Ecosystems are most interesting, so be prepared to defend you topic!!!  Sci Name______Date______Hour_____
