Tangled Web and a Missing Organism

Students will participate in an interactive activity in small groups. After briefly finding out what their organisms consume or what consume them, students will physically connect organisms using string and pushpins. Once the web is tangled, you will go around and designate a "removed" organism. Students will follow all the strings attached and explain how the connected organisms are affected. Eventually, in the mist of the class discussion, students will realize that the entire ecosystem is affected.
