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.</p><p>Also, we will participate in DEBATES concerning which Ecosystems are most interesting, so be prepared to defend you topic!!!  Sci Name______Date______Hour_____</p><p>Aquatic Ecosystems RESEARCH</p><p>I.
