This lesson introduces students to the broad concept of invasive species. Students prepare a written case study on an invasive aquatic species, followed by an oral presentation. They will define, compare, and contrast invasive species, alien species, and native species, describe at least three problems that may be associated with invasive species, and describe at least three invasive species, explain how they came to be invasive, and discuss what can be done about them. The lesson plan provides a list of possible species to choose from, and information about their introduction, impact, and control. Suggestions for extensions are also provided.
