Climate Change: Causes and Evidence

Active learning works for this topic because students need to connect abstract data to tangible, real-world consequences. When students model melting ice or analyze vulnerability profiles, they transform global statistics into personal, geographic realities they can discuss and debate.

Activity 01

Simulation Game40 min · Small Groups

Simulation Game: The Melting Point

Using two containers of water, one with ice 'on land' (on a rock) and one with ice 'in the water,' students observe which causes the water level to rise as it melts. They then discuss the geographic impact of melting glaciers versus sea ice.

Analyze the scientific evidence supporting the reality of global climate change.

Facilitation TipDuring The Melting Point simulation, circulate with a stopwatch to keep groups accountable for timed data collection intervals.

What to look forProvide students with two statements: 1) 'Burning coal for electricity is a natural process that has always happened.' 2) 'The Earth's temperature has always gone up and down.' Ask students to write 'True' or 'False' for each and provide one sentence of scientific reasoning for their answer, referencing greenhouse gases or human activities.

Activity 02

Gallery Walk45 min · Small Groups

Gallery Walk: Vulnerability Profiles

Display 'vulnerability cards' for different regions (e.g., the Canadian Arctic, the Maldives, the Sahel). Students move around to identify the primary threat to each region (flooding, permafrost melt, drought) and one way the local people are adapting.

Explain how human activities contribute to the greenhouse effect.

What to look forDisplay images of different human activities (e.g., driving a car, planting a tree, a factory emitting smoke, a solar panel). Ask students to hold up green cards for activities that increase greenhouse gases and red cards for those that decrease them or have no impact. Follow up by asking students to explain their choices for two of the images.

Think-Pair-Share25 min · Pairs

Think-Pair-Share: Food Security

Show a map of how wheat-growing regions in Canada might shift north as temperatures rise. Students discuss with a partner: Is this a 'good' thing? What are the challenges of farming in the rocky soil of the Canadian Shield?

Differentiate between natural climate variability and human-induced climate change.

What to look forPose the question: 'Imagine you are explaining the difference between natural climate changes and human-caused climate change to a younger sibling. What are the two most important things you would tell them?' Facilitate a brief class discussion, noting key points on the board.

A few notes on teaching this unit

Teach this topic by grounding discussions in students' lived experiences of weather, then layering scientific data to reveal climate patterns. Avoid overwhelming students with global averages; instead, focus on case studies they can relate to. Research shows that when students visualize thermal expansion with warm water and ice cubes, they retain the concept of sea-level rise better than with charts alone.

Successful learning looks like students explaining causal chains from greenhouse gas emissions to regional impacts, using evidence from simulations and gallery walk profiles. They should confidently distinguish between weather variability and long-term climate trends when discussing extreme events.

Watch Out for These Misconceptions

  • During The Melting Point simulation, watch for students attributing sea-level rise primarily to sea ice melt. Redirect their attention to the graduated cylinders showing water level changes when ice is added to water versus when ice is placed on land.

    During The Melting Point simulation, remind students that the water level rises only when ice on land melts, illustrating thermal expansion with the warm water in the basin.

  • During Gallery Walk: Vulnerability Profiles, watch for students equating 'extreme weather' with only heatwaves. Redirect their focus to the profile cards showing events like hurricanes, floods, and cold snaps to highlight climate instability.

    During Gallery Walk: Vulnerability Profiles, ask students to categorize the extreme weather events on each profile card by type and frequency to challenge the idea that climate change means only warmer temperatures.
