This lesson introduces students to invasive species. Students learn about invasive species by studying the example of the Indonesian Brown Tree Snake and its devastating effect on the birds of Guam. A link to a short video is included. The powerpoint then shows them other examples, including kudzu, zebra mussels, rabbits in Australia, and the snakehead fish. Lastly, students examine two food webs containing the invasive species garlic mustard- its native food web from Europe, and the food web it has entered in the United States. Students then learn that garlic mustard is nutritious and can be eaten by humans. They examine garlic mustard for themselves, look at a recipe for making “pest pesto”, and answer whether they would eat it for themselves.
TWO NOTES: 1) If you live in an area that has not been infested with garlic mustard, the last activity can be dropped or easily modified for a local invasive. For example, dandelions are also edible. 2) I really wanted to actually make the pesto for my students to try, but decided not to because of allergy concerns. If you do decide to have your students eat the garlic mustard, make certain you have correctly identified the plant and that you have gathered the plant from a pesticide-free area. Be careful where you throw the plant out. The flowers and seed pods should be burned.
