Regional Impacts of Climate Change
Examination of how different geographic regions are disproportionately affected by climate change and its varied impacts.
Key Questions
- Analyze why the impacts of climate change are felt disproportionately by the global south.
- Compare the specific climate change challenges faced by coastal vs. inland regions.
- Predict the long-term geographic shifts caused by regional climate impacts.
Ontario Curriculum Expectations
About This Topic
Population Dynamics examines the factors that influence the size and growth of species populations over time. Students explore concepts like carrying capacity, limiting factors, and predator-prey relationships. This topic is essential in the Ontario curriculum for understanding how ecosystems maintain balance and how human intervention can disrupt that balance.
By analyzing population data, students can predict the impact of environmental changes and invasive species. Students grasp this concept faster through structured discussion and peer explanation, where they use simulations to see the immediate effects of changing variables on a population's survival.
Active Learning Ideas
Simulation Game: Oh Deer!
Students act as deer and resources (food, water, shelter) in an outdoor or gym setting. They track the deer population over several 'years' to see how it fluctuates based on resource availability.
Inquiry Circle: Yeast Population Growth
Groups set up yeast cultures with different amounts of sugar and measure the population growth over several days using a microscope or turbidity measurements, plotting the resulting S-curve.
Think-Pair-Share: Invasive Species Impact
Students research a local invasive species (e.g., Zebra Mussels, Emerald Ash Borer). They discuss with a partner how the lack of natural predators allows the population to grow unchecked.
Watch Out for These Misconceptions
Common MisconceptionPopulations will continue to grow forever if there is enough food.
What to Teach Instead
Other factors like space, disease, and predation also limit growth, leading to a carrying capacity. Using a simulation to show 'crowding' effects helps students understand these multiple limiting factors.
Common MisconceptionPredators are 'bad' for a prey population.
What to Teach Instead
Predators often keep the prey population healthy by removing the weak and preventing overgrazing. Peer discussion of the Yellowstone wolf reintroduction helps students see the positive role of predators.
