“This past summer I was lucky enough to intern with the Illinois Indiana Sea Grant and rediscovered my love of marine sciences. My internship taught me a great deal about freshwater ecosystems and problems that are occurring in the Great Lakes. I was able to learn so much about the Great Lakes ecosystems, limnological studies, and nutrient levels, and I gained hands on experience working on the US EPA R/V Lake Guardian research vessel collecting nutrient and biological samples. The internship also allowed me to work at the Illinois State Fair and educate the public about the many issues facing the Great Lakes. It was a great feeling to spread the word about how we can all make a change in our behavior so that we can make a difference in our environment! I am currently interning with Oak Ridge Institute of Science and Education (ORISE) and continuing to work on Great Lakes projects and take samples from the Great Lakes on the US EPA R/V Lake Guardian. The Illinois Indiana Sea Grant internship really helped further my contacts in the industry by networking and meeting people working in different areas of the Great Lakes. Illinois Indiana Sea Grant really opened my eyes to a whole new field and career opportunities. I cannot thank them enough!”

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.
