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. It contains nine 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.

Understanding future water demand is key to managing these resources sustainably. The Chicago Metropolitan Agency for Planning (CMAP), Illinois-Indiana Sea Grant (IISG), and University of Illinois Extension recently updated the region’s water demand forecast to reflect new population and employment projections. The forecast shows that water use is expected to continue declining, due to steady advances in water conservation and efficiency that are outpacing population and employment growth. However, in some areas, forecasted water demand will exceed available groundwater supplies.

Aquaponics: Farming Fish, Growing Greens teaches STEM through aquaponics, a water-based agricultural system that combines aquaculture and hydroponics. This 9-12 grade curriculum was designed to be used along with an onsite aquaponics system. Curriculum topics include an Introduction to aquaculture, fundamental parts of an aquaponics system, the nitrogen cycle, water quality, population dynamics, our modern food system and more. Lessons were developed to build on each other and be delivered in sequence but can also be used individually.
