Quadratic Functions and Relations · Term 2

Graphing Quadratics in Standard Form

Students will graph quadratic functions given in standard form (y = ax^2 + bx + c) by finding the vertex and intercepts.

About This Topic

Climate Change Impacts examines the tangible consequences of a warming planet, from melting permafrost in Northern Canada to shifting agricultural zones in the south. Students analyze evidence such as ice core data and sea-level records to understand the scale of the current crisis. This topic aligns with Ontario's commitment to environmental education and Indigenous perspectives on the land.

By focusing on local and global impacts, students develop a sense of urgency and agency. This topic particularly benefits from hands-on, student-centered approaches where students analyze real-world datasets or engage in role plays to develop adaptation strategies for their own communities.

Active Learning Ideas

Inquiry Circle: Ice Core Mystery

Students are given 'ice cores' (frozen cylinders of water with layers of sediment and trapped air bubbles). They must 'excavate' and analyze the layers to reconstruct a timeline of past environmental conditions.

Role Play: The Climate Adaptation Council

Students represent different stakeholders (farmers, Indigenous leaders, city planners, wildlife biologists) in an Ontario town facing increased flooding. They must agree on a budget for adaptation projects.

Gallery Walk: Climate Change in My Backyard

Students research a specific impact of climate change in Canada (e.g., pine beetle outbreaks, coastal erosion in PEI). They present their findings and potential solutions to their peers.

Watch Out for These Misconceptions

Common Misconception

Sea level rise is only caused by melting glaciers and ice caps.

What to Teach Instead

Thermal expansion of the ocean water as it warms is a major contributor. A simple experiment with a flask of water and a heat lamp can demonstrate that water expands as its temperature increases.

Common Misconception

Climate change just means it will get slightly warmer everywhere.

What to Teach Instead

It involves more extreme weather, changing precipitation patterns, and ecological shifts. Peer discussion of 'global weirding' helps students understand the complexity of the changes.

Frequently Asked Questions

How can active learning help students understand climate change impacts?

Active learning, such as data analysis and role-playing, moves students from climate anxiety to climate literacy. By working with real Canadian climate data, they see the evidence for themselves. Role-playing adaptation scenarios helps them understand the socio-economic challenges of climate change, fostering critical thinking about how communities can build resilience in a changing world.

How do scientists know what the climate was like in the past?

Scientists use 'proxy data' from ice cores, tree rings, and sediment layers to reconstruct past temperatures and atmospheric compositions.

What is the impact of melting permafrost?

Melting permafrost can damage infrastructure in the North and release large amounts of stored methane, further accelerating global warming.

Why are sea levels rising?

Sea levels are rising due to the melting of land-based ice (glaciers and ice sheets) and the thermal expansion of seawater as it absorbs heat.
