2008 Great Lakes Rock!Excellent presentation, Dr. Lusch. I think I have learned more during your 30 minutes than I have in any previous geology course! Your analogies are wonderful, and I already plan on using them in the classroom. Thank you for the offer of the use of your PowerPoint in the classroom. I've already gone to your site & found more great resources there. Thank you!

Standards and Principles Science Education Standards

To be effective in working with teachers, scientists must become informed about the content expectations in science classrooms.

Great Lakes Literacy (the goal of COSEE-GL) A Great Lakes literate person:

understands the essential principles and fundamental concepts about the characteristics, functioning and value of the Great Lakes;

can communicate accurately about the Great Lakes’ influence on systems and people in and beyond their watershed; and

is able to make informed and responsible decisions regarding the Great Lakes and the resources of their watershed.

Standards and Principles

Ocean LiteracyPrinciples

Great Lakes Literacy Principles

1. The Earth has one big ocean with many features.

1. The Great Lakes, bodies of fresh water with many features, are connected to each other and to the world ocean.

2. The ocean and life in the ocean shape the features of the Earth.

2. Natural forces formed the Great Lakes; the lakes continue to shape the features of their watershed.

3. The ocean is a major influence on weather and climate.

3. The Great Lakes influence local and regional weather and climate.

4. The ocean makes Earth habitable. 4. Water makes Earth habitable; fresh water sustains life on land.

5. The ocean supports a great diversity of life and ecosystems.

5. The Great Lakes support a broad diversity of life and ecosystems.

6. The ocean and humans are inextricably interconnected.

6. The Great Lakes and humans in their watersheds are inextricably interconnected.

7. The ocean is largely unexplored. 7. Much remains to be learned about the Great Lakes.

8. The Great Lakes are socially, economically, and environmentally significant to the region, the nation and the planet.

Natural forces formed the Great Lakes; the lakes continue to shape the features of their watershed Ancient igneous and metamorphic rocks form

portions of the upper Great Lakes basin. Most rocks underlying the present day Great Lakes and the surrounding watershed are sedimentary, and originated as deposits within shallow tropical seas that once covered the basin.

Most of the surficial sediments in Michigan were deposited and shaped during the advance and retreat of continental glaciers.

Natural forces formed the Great Lakes; the lakes continue to shape the features of their watershed During the Ice Age, mile-thick sheets of ice covered

the Great Lakes region multiple times, depressing the crust with their weight. Ancient beach ridges or wave-cut cliffs mark previous Great Lake shorelines. Since the glaciers retreated (about 10,000 years ago), the Earth’s crust has been adjusting upward in a process of isostatic rebound that continues today.


20 / 24

ISOSTATIC REBOUND - With glacial melting, the tremendous weight of the ice was lifted from the North American Plate and the land surface, noticeably depressed during the glacial maximum, began to rebound upward. This process continues today in Michigan at a rate of about 7.5 cm per century.

Do not attempt composing lesson plans without the active participation of classroom teachers Always link your material to appropriate Grade

Level Content Expectations Provide opportunities for field testing the lesson

plan materials before mass dissemination Use appropriate/alternative technology within the

lesson plan (not everyone has super-fast Internet access)

Involve classroom teachers
