The use of live crayfish in classrooms has been identified as a pathway for the introduction of invasive crayfish into our local waterways. To address this issue, the Investigating Crayfish and Freshwater Ecosystems curriculum was developed to teach students about Great Lakes ecosystems, the significance of native crayfish, and the ecological threats posed by invasive crayfish.

This curriculum comprises nine engaging lesson plans aligned to Next Generation Science Standards, Common Core State Standards, and Center for Great Lakes Literacy Principles. The curriculum is best suited for students in grades 6–12, but offers numerous adaptations/extensions to meet the divergent needs of students in grades 2–5.

 Investigating Crayfish and Freshwater Ecosystems was developed by Engaging Every Student and Illinois-Indiana Sea Grant.
