Do Insects Prefer Local Or Foreign Foods? is a lesson plan that provides a sequence of learning activities to help students understand what might determine if an exotic species will become invasive. This lesson is divided into four parts. In the first part, students are introduced to the phenomenon of invasive plant species and asked the scientific questions, "How does insect herbivore damage compare for native, non-invasive exotic, an invasive plant species?" and "Are species that have become invasive in Michigan not eaten by herbivore?". Students find the hypothesis in "Research Background" and make three predictions for the amount of herbivory on the three plant types. In the second part, students are provided the data from this investigation, answer questions about the variables, and except for Student Version A, generate a bar graph. The last part of the lesson is the interpretation of the data. The lesson plan uses four main questions to guide students through a claims-evidence-reasoning response. The fourth and final activity provides students an opportunity to experience science as an ongoing process by exploring whether this study fully answered the research questions and what new questions could be investigated. There are three different versions of this lesson provided so that the teacher may differentiate instruction. Background research, a general rubric, possible student responses, and supportive "Teacher Notes" are provided. An extension activity is also provided that is appropriate for high school students as well as additional teacher resources related to this Data Nugget that allow students to collect their own data.
