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.

This summer, 15 Great Lakes educators swapped lesson plans for life jackets as they boarded the Lake Guardian, the U.S. Environmental Protection Agency’s research vessel, and set sail on Lake Michigan. Through the Shipboard Science Immersion program, 5–12 grade formal and non-formal educators worked side by side with Great Lakes scientists for a week—an experience they say will ripple back to their classrooms for years to come.

Last month, Illinois and Indiana educators gathered for a two-day, professional learning workshop hosted by @duneslearning, @indianadnr, @thengrrec, and Illinois-Indiana Sea Grant to dive deep into water’s role in Earth’s systems
Using @projectwet’s newest guidebook, Water in Earth Systems, participants explored the unique ecosystems of @indianadunesnps and engaged in hands-on aquatic science activities—bringing Great Lakes learning to life in the classroom!
Thanks to all who joined us in connecting science, stewardship, and the Great Lakes!
