Food Web

We enacted a food web, using organisms that live in the Narragansett Bay.  Each student represented a certain organism and touched hands with anyone who represented something it eats or is eaten by.  Then we introduced different scenarios that would impact one organism, and then have ripple effects on the whole eco-system.  Students then worked on their own definitions of a food web and listed characterise of an eco-system.  Several fifth graders connected this concept to the greater field of systems thinking, which we touched upon at the start of the school year.
