Glacial Landforms & Freshwater Systems
Investigating the processes of glaciation and how they shaped Canada's landscape, including the formation of the Great Lakes.
Key Questions
- Explain the geological processes that led to the formation of the Great Lakes.
- Analyze the evidence of glacial erosion and deposition visible in the Canadian landscape today.
- Hypothesize how the retreat of glaciers influenced early Indigenous migration routes and settlement patterns.
Ontario Curriculum Expectations
About This Topic
Canada's diverse geography brings a wide range of natural hazards, from earthquakes in British Columbia to ice storms in Ontario and wildfires in the Prairies. This topic focuses on assessing risk and understanding the human impact of these events. Students analyze how physical processes (like plate tectonics or atmospheric pressure) lead to disasters and how communities can prepare for them.
This unit emphasizes the concept of 'mitigation', the steps we take to reduce the severity of a hazard. It is a critical part of the curriculum because it connects physical geography to public safety and urban planning. Students grasp this concept faster through simulations where they must make high-stakes decisions about resource allocation during a mock disaster.
Active Learning Ideas
Simulation Game: Disaster Response Team
Divide the class into 'Emergency Management' teams. Each team is given a scenario (e.g., a major flood in Calgary) and a limited budget to decide which infrastructure to save and how to evacuate residents.
Gallery Walk: Hazard Mapping
Students create maps showing the 'hot zones' for different hazards in Canada. They circulate and identify which regions are 'multi-hazard' zones and discuss why those areas might be difficult to insure.
Think-Pair-Share: The Human Factor
Pairs discuss how human activities, like building on floodplains or clear-cutting forests, can make natural hazards worse. They share one specific example they have seen in the news.
Watch Out for These Misconceptions
Common MisconceptionNatural disasters are completely unpredictable.
What to Teach Instead
While the exact timing is hard to pin down, geographers use historical data and patterns to identify high-risk areas. Analyzing 'return periods' for floods helps students understand how we predict risk.
Common MisconceptionOnly the West Coast has to worry about earthquakes.
What to Teach Instead
Parts of Ontario and Quebec, particularly the Ottawa and St. Lawrence valleys, are also seismic zones. Looking at historical earthquake maps of Eastern Canada helps correct this regional bias.
