Towards the beginning of the school year, my class spent about a month on our “Aquatic Habitats and Biodiversity” unit. After exploring the general nature of aquatic systems (both marine and freshwater), we took a closer look at our local water systems, specifically Lake Michigan. During this time, we discussed the history of the Great Lakes, identified the various ways in which humans have used and altered the makeup of the Great Lakes, spent two days conducting water-quality testing and macro-invertebrate sampling (using both biotic and abiotic indicators to compare water quality in various tributaries to that of the mouths in which they fed into Lake Michigan), and debated plausible methods to prevent invasive species such as the Asian Carp from entering the Great Lakes.
Throughout this entire unit, I found myself regularly referencing experiences I had during the Lake Guardian summer workshop. The experiences not only allowed me to better explain the complexity of some of these issues, but it also opened my students’ eyes to hands-on opportunities available in the world of science. It taught me a great deal about the Great Lakes, but, more importantly, it improved my ability to teach students about the Lakes’ significance. I hope this program continues to be funded for years to come as it is a wonderful way of spreading both knowledge and passion regarding the importance of preserving the gift that is the Great Lakes.

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.

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.

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.
