The history of an area can tell us much about what might be affecting the environment.

So, today we read “clue cards” with tidbits of information about the last 100 years of history in the Gray Area. Students put the clues on a timeline. That way it made it easier to analyze recent changes since they can affect the health of the fish.

After processing all the clues, we moved to the class wiki. Students wrote individual posts that stated their opinions about what is killing the fish. The great feature of a wiki is that after writing a post, writers can comment on the posts of other students in the class. Sometimes students disagree with each other. (Imagine!)

Get ready. The situation in the Gray Area is of such great concern that a board of supervisors meeting has been called.
