Trimming Our Sails 2021

Take a deep dive with Sea Grant this summer and investigate maritime underwater shipwrecks and how aquatic invasive species impact water quality, the food web, and shipwrecks over a two day workshop series.

Day one explores maritime archaeology and Great Lakes shipwrecks with a feature presentation by Tamara Thomsen, maritime archaeologist, photographer, researcher, and research diver. On day two join NOAA scientist and benthic ecologist, Dr. Ashley Elgin, for a discussion on zebra mussels and how aquatic invasive species impact water quality, the food web, and shipwrecks.

In addition to a guest speaker, each workshop will investigate fascinating aspects of shipwrecks and aquatic invasive species and the connection each have to the Great Lakes Literacy Principles. Workshops will also feature hands on activities for your learners, provide suggestions for classroom applications and a chance to share and network with other education professionals. Workshop materials will suggest relevant Minnesota academic standards and benchmarks, Wisconsin academic standards, Common Core Standards and Next Generation Science Standards.
