Students will examine the effect of exotic species on an ecosystem by role-playing both a healthy food chain and one that has been impacted by Mayan cichlids. Students will also be able to discuss a basic food chain, define and give examples of exotic species, and discuss how exotic species can disrupt a food chain.


Our "Don't let it Loose" unit is broken into seven lesson plans, each taking 45 minutes to 4 classroom periods to complete, and targeted primarily at middle school students. A class needn't complete every lesson in the unit, though some lessons do refer to one another. However, each lesson comes with its own set of objectives and resources.
