The Great Lakes and Water Security: ManagementActivities & Teaching Strategies
Active learning transforms abstract policy discussions into concrete, student-centered experiences. For this topic, students move beyond memorizing facts to grappling with real-world trade-offs in water management, which builds both content knowledge and civic engagement skills. Hands-on activities make the finite nature of freshwater visible and the importance of binational cooperation tangible.
Learning Objectives
- 1Analyze the binational management strategies employed by Canada and the U.S. for the Great Lakes, citing specific agreements like the GLWQA.
- 2Explain the ecological and anthropogenic threats impacting the Great Lakes ecosystem, such as invasive species and pollution.
- 3Evaluate the effectiveness of current policies and international bodies, like the IJC, in protecting Great Lakes water quality and security.
- 4Compare and contrast areas of cooperation and conflict between Canada and the U.S. regarding Great Lakes resource allocation.

Jigsaw: Great Lakes Policies
Divide the class into expert groups, each assigned a policy like GLWQA or ballast water regulations. Experts study documents for 10 minutes, then regroup to teach peers and evaluate effectiveness. Conclude with a whole-class vote on strongest policies.
Prepare & details
Analyze how Canada and the U.S. cooperate (or conflict) over water management.
Facilitation Tip: During the Jigsaw Activity: Great Lakes Policies, group students by policy topic and assign each group a specific section of the GLWQA to analyze before regrouping into mixed teams.
Setup: Flexible seating for regrouping
Materials: Expert group reading packets, Note-taking template, Summary graphic organizer
Debate Stations: Cooperation vs. Conflict
Set up stations for key issues: water diversion, pollution, invasives. Pairs prepare pro/con arguments using provided sources, rotate stations debating with other pairs. Facilitate a final synthesis discussion.
Prepare & details
Explain the primary threats to the health of the Great Lakes ecosystem.
Facilitation Tip: For Debate Stations: Cooperation vs. Conflict, provide clear time limits and role cards to keep discussions focused on the assigned scenario.
Setup: Chairs in rows facing a front table for officials, podium for speakers
Materials: Stakeholder role cards, Issue briefing document, Speaking request cards, Voting ballot
Threat Mapping: Interactive GIS
Provide maps or digital tools for small groups to plot threats like urban runoff or warming waters. Groups research data, add layers, and propose management solutions. Share maps in a gallery walk.
Prepare & details
Evaluate the effectiveness of current policies for Great Lakes protection.
Facilitation Tip: In Threat Mapping: Interactive GIS, pre-load base maps with key layers and guide students to identify spatial relationships between threats and human activities.
Setup: Chairs in rows facing a front table for officials, podium for speakers
Materials: Stakeholder role cards, Issue briefing document, Speaking request cards, Voting ballot
Policy Role-Play: IJC Simulation
Assign roles as Canadian officials, U.S. stakeholders, environmentalists. Groups negotiate a response to a hypothetical drought. Debrief on real vs. simulated outcomes.
Prepare & details
Analyze how Canada and the U.S. cooperate (or conflict) over water management.
Facilitation Tip: During Policy Role-Play: IJC Simulation, assign roles with distinct perspectives (e.g., Indigenous community representative, industrial lobbyist) to ensure diverse viewpoints are represented.
Setup: Chairs in rows facing a front table for officials, podium for speakers
Materials: Stakeholder role cards, Issue briefing document, Speaking request cards, Voting ballot
Teaching This Topic
Experienced teachers approach this topic by grounding abstract policies in student experiences with local water issues. They avoid presenting cooperation as automatic, instead designing simulations that reveal the complexities of negotiation across borders. Research suggests that role-playing and GIS mapping deepen understanding of spatial relationships, while jigsaw activities build both content mastery and collaborative skills.
What to Expect
Successful learning is evident when students can articulate trade-offs between economic needs and ecological protection during policy debates. They should also identify specific examples of cooperation between Canada and the U.S. and explain how GIS tools reveal spatial patterns of threats. Participation in simulations and discussions demonstrates their ability to apply management concepts to new scenarios.
These activities are a starting point. A full mission is the experience.

Watch Out for These Misconceptions
Common MisconceptionDuring Jigsaw Activity: Great Lakes Policies, watch for students claiming the Great Lakes have unlimited water. Redirect them by having groups calculate water budgets using provided data on withdrawals, diversions, and evaporation rates.
What to Teach Instead
During Threat Mapping: Interactive GIS, confront the idea that management is handled separately by Canada and the U.S. by pointing students to the IJC’s shared decision-making structure on the GIS platform.
Common MisconceptionDuring Debate Stations: Cooperation vs. Conflict, watch for students asserting that policies have fully protected the Great Lakes ecosystem. Redirect them by asking groups to compare pre- and post-GLWQA data on algal blooms or other indicators.
What to Teach Instead
During Policy Role-Play: IJC Simulation, challenge the assumption that cooperation is automatic by assigning roles with conflicting priorities and requiring students to propose compromise solutions.
Assessment Ideas
After Policy Role-Play: IJC Simulation, pose the following to small groups: 'Imagine you are representatives at an IJC meeting discussing a proposal to divert water from Lake Superior for industrial use. What arguments would you make for or against this diversion, considering both economic needs and ecological impacts?'
After Threat Mapping: Interactive GIS, provide students with a short case study describing a current threat to the Great Lakes (e.g., a new algal bloom or an invasive species sighting). Ask them to identify the primary cause of the threat and one policy or management action that could address it.
After Jigsaw Activity: Great Lakes Policies, ask students to write on an index card: 1) One specific example of cooperation between Canada and the U.S. regarding the Great Lakes. 2) One significant threat to the Great Lakes ecosystem that requires ongoing management.
Extensions & Scaffolding
- Challenge early finishers to design a public service announcement advocating for a specific Great Lakes policy, incorporating data from their GIS maps.
- For struggling students, provide sentence stems during the debate activity (e.g., 'One concern is... because...') and a word bank of key terms like 'ecosystem services' or 'sustainable yield'.
- Deeper exploration: Invite students to research a current Great Lakes policy proposal (e.g., from the IJC’s 2023 report) and present a mock stakeholder meeting to the class.
Key Vocabulary
| Great Lakes Water Quality Agreement (GLWQA) | A binational agreement between Canada and the United States, first signed in 1972, aimed at restoring and protecting the Great Lakes ecosystem. |
| International Joint Commission (IJC) | A binational organization established by treaty in 1909 to help the United States and Canada prevent and resolve disputes over their shared water resources. |
| Invasive Species | Organisms that are not native to a particular area and can cause harm to the environment, economy, or human health, such as zebra mussels in the Great Lakes. |
| Nutrient Pollution | Excessive amounts of nutrients, primarily phosphorus and nitrogen from agricultural runoff and wastewater, that can lead to harmful algal blooms in water bodies. |
| Water Diversion | The intentional movement of water from one river basin, lake, or watershed to another, often for agricultural, industrial, or municipal use. |
