This lesson will explore the phenomenon of invasive species in the Great Lakes, specifically the sea lamprey, to help students learn how predator-prey relationships affect populations in an ecosystem, why invasive species like the sea lamprey pose a threat to the Great Lakes, and which efforts can most successfully control them.

Lesson Objectives

  • Know why sea lamprey pose a threat to the Great Lakes ecosystem
  • Understand what measures have been taken to try and control the sea lamprey population
  • Be able to research and defend the best possible solutions to the sea lamprey threat in the Great Lakes

Activity 1

This activity is a video discussion of a Great Lakes Now episode segment that features the invasive sea lamprey species in the Great Lakes and what is being done to control it. During the video students need to jot down four things they took away from it.

Activity 2

The challenge of eliminating an invasive species from an ecosystem is complex, but could be achievable using genetic engineering. This activity introduces students to the way that genetic alteration technology is being used to control—and possibly eliminate—the sea lamprey population in the Great Lakes.

Activity 3

In order to learn about DNA and develop technologies with it, scientists first need to be able to get DNA out of an organism in the first place to study it and work with it. So, how does that happen? Using a lab technique called DNA extraction.

Activity 4

This activity invites students to research existing solutions, or generate novel ideas for potential solutions, for sea lamprey population control. As part of their research project, they will design a proposal for what they think is the best solution possible and defend their proposal in a town hall presentation to a group of stakeholders.
