Fourteen teachers from throughout the Great Lakes basin embarked on the learning opportunity of a lifetime this month, taking part in a week-long workshop aboard the U.S. Environmental Protection Agency’s research vessel Lake Guardian. They explored first-hand Lake Huron’s geology, limnology (freshwater science), and ecology, with a special focus on the food web as it relates to Huron’s fisheries. 
 
The teachers worked side-by-side with scientists learning a great deal about what comprises research on the Great Lakes. They assisted with the collection of planktonic and benthic organisms, as well as gathering water quality data. They also explored Great Lakes curriculum and discussed how to integrate this information in their classrooms. You can see visit their blog and learn more at cossegreatlakes.net. This program is offered annually by EPA’s Great Lakes National Program Office and the Great Lakes Sea Grant Network. If you are an educator, consider applying next year for the cruise on Lake Ontario!
