Reviewer Comments:

In this quick activity, late elementary through middle school students will study the Great Lakes food web by passing yarn back and forth, creating an interconnected web. After discussion, they will visually simulate the impact of changes in this food web. This activity includes a very clear procedure and could be implemented immediately into the classroom. The lesson is aligned to the Common Core State Standards and to state learning standards in a number of Great Lakes-surrounding states.
