Fresh and Salt is a collection of activities that enhance teacher capabilities to connect Great Lakes and ocean science topics. Designed to be used by teachers in grades 5-10, Fresh and Salt provides an interdisciplinary approach to ensure that students achieve optimum science understanding of both Great Lakes and Ocean Literacy Principles. This curriculum offers a varied range of instructional modes, including data interpretation, experimentation, simulation, interactive mapping, and investigation.

The 14 activities that make up Fresh and Salt were selected for their capacity to provide science process skills that students need for effective learning. This curriculum can also help prepare students to be responsible decision-makers that promote a sustainable society.

This project was led by IISG with funding and support from COSEE Great Lakes. Visit the IISG website to download or order a copy of Fresh and Salt.

When participating in a crayfish participatory science activity, be sure to snap plenty of photos of any crayfish you catch or observe. Not only is it a great way to capture the fun and excitement of the day, but it also helps document the species present. To ensure accurate identification by scientists, it’s important to provide clear photos from multiple angles. Dorsal (top), lateral (side), and ventral (underside) views of the crayfish should always be photographed.To learn more about the specific features to highlight in your photos visit the link in bio or InvasiveCrayfish.org/Management/#Community
Who says “Back to School” means back indoors? While the weather is still warm, take your students on an outdoor science adventure by exploring crayfish in your local waterways.The Invasive Crayfish Collaborative invites grades 2-12 educators to take part in a hands-on participatory science activity. By catching, identifying, and reporting crayfish species in your area, students contribute valuable data that helps scientists better understand where native and invasive crayfish live.Check out what other educators have found and get involved: inaturalist.org/projects/great-lakes-crayfish
