Students learn about bacteria as an indicator of beach water quality for swimming. In groups they solve
hypothetical problems associated with beaches. Then students write persuasive essays on the issue.
- Discuss the effect of harmful bacteria on swimming conditions at beaches.
- Diagram three reasons for beach contamination.
- Explain solutions for beach health problems.
- Write a persuasive essay about beach health
Hydropoly: A Decision Making Game
Students play a board game to hone their decision-making skills. Through the various choices posed in the game, they are asked to consider both economic and environmental well being in making decisions.
- Discuss land-use practices that affect Great Lakes wetlands
- Make decisions and recognize personal priorities with regard to wetlands
- Describe some of the economic factors that often drive land use
Students study Creature Cards at sand dune ecosystem stations and determine what adaptations help the organisms to live in their environments.
- List organisms that live in the dunes.
- Describe the specialized adaptations of sand dune organisms.
- Explain the different habitats in sand dunes.
Wetland in a Pan
Students build a model wetland to understand that wetlands are defined by plants, soil and water, identify some wetland types and their locations, and relate importance of wetland function to people’s needs and daily lives.
Seeing Purple: A Population Explosion
Through a simulation, sampling, and estimation activity, students learn about the impact of purple loosestrife on a wetland due to its exponential growth. They learn about purple loosestrife’s life cycle and appreciate how scientists determine population size in an ecosystem.
Don’t Stop for Hitchhikers!
Students role-play the part of lake inhabitants and the aquatic exotics who displace the native species. Props are used to help demonstrate how aquatic exotic species enter a lake or river system, the negative effect they have on the native species, and things people can do to stop the spread of exotic species.
Students will be able to:
- Identify exotic species and ways they are transported.
- Learn about several exotics that affect water habitat.
- Identify the negative or positive effects of exotic species on native animals.
- Know how these exotics are transported and ways people can help to stop further spread.
Ojibway—Early Immigrants to the Great Lakes Region
This activity introduces students to one tribe of early Great Lakes settlers, the Ojibway (Chippewa), who began to migrate from what would later become New Brunswick and Maine in 900 A.D.
How do the Great Lakes Modify the Growing Season?
Using agricultural product and frost maps and an infrared satellite image, students develop a hypothesis about the effect of the lakes on growing seasons and then create a model to test the hypothesis.
