Rival for Survival

This game presents real-life choices involving exotic species found in the Great Lakes, such as zebra mussels and purple loosestrife. Students are to analyze a situation related to ecology and make an environmentally sound decision. After playing the game, students organize what they learned into a  concept map.

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.

Trees on the Move: Can Maples and Buckeyes Migrate?

Activity A: What do climate models predict about tree ranges?
This lesson introduces examples of how General Circulation Models [GCMs] predict possible scenarios of climate change. Three methods of visualizing change are introduced and students compare how sugar maples and buckeye trees’ climate niches are likely to be altered.

Activity B: How can trees migrate?
The seeds of maples and buckeyes are “dispersed” in an outdoor simulation of how far a tree species might be able to spread over several tree generations.

Activity C: How does temperature affect maple seed germination?
Students examine research data on seed germination at different temperatures to infer some of the impacts of temperature on species survival.

Activity D: After the maples, then what?
Students study an outdoor area that has sugar maples and other species. Following research methods of Catherine Keever, they catalog the size and relative abundance of species in the plot and infer what species is likely to succeed if maples disappear.
