Students begin by matching images of common invasive species with their characteristics and impacts. Students then engage in an activity that simulates the impacts of Eurasian ruffe on the natural ecosystem of the St. Louis River.
This lesson uses modeling as a method for problem solving and a tool for understanding scientific principles. Evaluation, collaboration and redesigning of models will further develop student science literacy skills.
