“In a follow-up to evaporation studies funded by the Great Lakes Integrated Sciences and Assessments Center, a federally funded collaboration between U-M and Michigan State University, Lenters and his colleagues developed a map-based water-temperature forecasting tool called SLATE, which stands for Seasonal Lake Temperature Energetics model.The experimental model was used to generate the Lake Superior forecast and may later be used to create similar surface-water temperature forecasts for all five Great Lakes—possibly even evaporation forecasts. SLATE is believed to be the first map-based forecasting tool that shows anticipated variations in surface-water temperature from place to place across one of the Great Lakes.The Lake Superior forecast is expected to be of interest to swimmers, boaters, anglers and others who will be affected by chilly water temperatures not seen since perhaps as far back as 1979.‘If you’re planning to go swimming in Lake Superior this summer, you should probably stay close to shore,’ said Peter Blanken, a co-investigator from the University of Colorado.The U.S. Coast Guard in Marquette has already expressed interest in using the Lake Superior forecast to help plan summer search-and-rescue operations. And a long-distance swimmer who is planning a trek from Milwaukee to Chicago in Lake Michigan this summer has also asked about water temperature forecasts.”

Looking for a fun, hands-on way to engage your students this year? Check out our new curriculum about crayfish and freshwater ecosystems! This curriculum teaches students about the importance of native crayfish, the threats posted by invasive species, and the health of Great Lakes ecosystems. It includes 9 ready-to-use lesson plans, with one featuring our participatory science activity! All lessons are aligned with NGSS, CCSS, and CGLL Principles.
Download the curriculum and start exploring at InvasiveCrayfish.org/Crayfish-Curriculum

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

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.
