Cut strips of paper. Label each strip with one organism found on the food web.
Begin assembling the strips of paper together in a chain - looping together the organisms that are in direct relationships with one another.
The finished product isn't a whole lot to look at, but this activity is really about the process.
After the food web is finished, you could rip out one of the links and talk about what would happen if that part of the food web was no longer available (a favorite standardized test question).
