Factors Influencing Canadian Climate
Students will analyze the 'LOWER N' factors (latitude, ocean currents, wind, elevation, relief, near water) that determine Canada's climate zones.
Key Questions
- Explain how latitude and ocean currents create distinct climate patterns across Canada.
- Analyze the impact of mountain barriers on precipitation and temperature in Western Canada.
- Differentiate between maritime and continental climates in Canada, providing examples of each.

About This Topic
The Canadian landscape is a product of the last Ice Age. This topic explores how the Laurentide Ice Sheet, which covered most of the country until about 10,000 years ago, acted as a giant sculptor. Students learn about the processes of erosion and deposition that created the Great Lakes, drumlins, moraines, and the rich agricultural soils of Southern Ontario.
Beyond the physical changes, this topic connects to the history of human migration. Students investigate how retreating glaciers opened corridors for Indigenous peoples to move across the continent. This topic comes alive when students can physically model the movement of glaciers using materials like putty or sand, allowing them to see how ice can move mountains and carve out basins.
Active Learning Ideas
Simulation Game: Glacial Sculpting
Students use 'glacier' blocks (ice with embedded gravel) to scrape across clay surfaces. They observe the resulting striations and deposition patterns, comparing them to real-world Canadian landforms.
Gallery Walk: Glacial Evidence
Display photos of Canadian landmarks like the Oak Ridges Moraine or the Great Lakes. Students rotate through the images, identifying whether each was formed by erosion or deposition.
Think-Pair-Share: The First Peoples' Path
Pairs analyze maps showing the retreat of ice sheets alongside archaeological sites. They discuss how the changing environment would have influenced the migration and settlement of Indigenous ancestors.
Watch Out for These Misconceptions
Common MisconceptionGlaciers are just stationary blocks of ice.
What to Teach Instead
Glaciers are actually 'rivers of ice' that flow under their own weight. Hands-on modeling with viscous materials helps students understand how glaciers move and transport massive amounts of debris.
Common MisconceptionThe Great Lakes have always existed.
What to Teach Instead
The Great Lakes were formed relatively recently by the weight of the glaciers and the meltwater left behind. Examining cross-section diagrams of the lakes helps students visualize the scouring process.
