TeachNetUSA: Crimes on the Great Lakes

Ignorant Shippers

Motivational Activity
There are many new species in the Great Lakes and other waterways that were never in them before.  They have been brought here in the ballast tanks of transatlantic freighters.  Water taken on in freshwater seas like the Caspian Sea contain plants and animals that are native to those waters.  Instead of exchanging the freshwater for salt water in mid ocean, these freighters come straight across the Atlantic Ocean.  Once they have reached the Great Lakes and take on new freight the old ballast is pumped out and the plants and animals.  These plants and animals no longer have any natural predators and multiply out of control.

Application Activities
You are to write an informative brochure about where 6 of these aquatic nuisance species have come from, how it got here and when, what kind of damage to the ecosystem it is causing, and how people can help reduce their spread.  This is to be a tri-fold brochure complete with title and map with invasive species located on it.
