About This Lesson

Resource: Invaders of the St. Lawrence

Description

Media (10 mins): The Great Lakes are a major hotspot for invasive species. How did they get there, and what can we do about it? Lexy visits experts from the River Institute and Mohawk Council of Akwesasne’s Environment program to find out. We’ll join researcher Cristina Charette in the lab to learn how the invasive round goby is changing the food web. Next, field technician Logan Lazore explains why researchers are worried that invasive zebra mussels may harm native species like sturgeon in the future.

  • See the media: Ocean School makes media/activity combinations. Each piece of media is linked to an activity.

Activity (1 hr 30 mins): Debate! Students are introduced to the ethics of controlling invasive species. Then they debate whether to eradicate or tolerate the round goby, an invasive fish in the St. Lawrence River.
