Tools of Monetary Policy
Students will examine how the central bank uses open market operations, the discount rate, and reserve requirements to influence the money supply.
Key Questions
- Explain how open market operations are the primary tool of monetary policy.
- Analyze the impact of a change in the reserve requirement on the money supply.
- Predict how a central bank might respond to a recession using its monetary policy tools.
Ontario Curriculum Expectations
About This Topic
The Greenhouse Effect explains how certain gases in Earth's atmosphere trap heat, maintaining a temperature suitable for life. Students investigate the role of carbon dioxide, methane, and water vapour in this process and how human activities are intensifying it. This topic is a critical part of the Ontario curriculum's focus on climate change and environmental stewardship.
By understanding the molecular basis of heat trapping, students can better evaluate climate data and policy. This topic comes alive when students can physically model the patterns, using simple experiments with jars and thermometers to simulate the atmospheric trapping of infrared radiation.
Active Learning Ideas
Inquiry Circle: Greenhouse in a Jar
Students set up two jars with thermometers, one filled with regular air and one with added CO2 (from an antacid tablet). They place both under a heat lamp and record the temperature change over time.
Think-Pair-Share: The Albedo Effect
Show images of melting Arctic ice. Students discuss how the change from white ice to dark water creates a feedback loop that accelerates the greenhouse effect.
Gallery Walk: Sources and Sinks
Stations feature different greenhouse gas sources (cattle, cars, permafrost) and sinks (forests, oceans). Students rotate to identify which are natural and which are human-influenced.
Watch Out for These Misconceptions
Common MisconceptionThe greenhouse effect is inherently bad and caused only by humans.
What to Teach Instead
The natural greenhouse effect is essential for life; without it, Earth would be frozen. Peer discussion helps students distinguish between the natural effect and the 'enhanced' greenhouse effect caused by human activity.
Common MisconceptionThe hole in the ozone layer is the main cause of global warming.
What to Teach Instead
Ozone depletion and the greenhouse effect are two different atmospheric issues. Using a Venn diagram activity helps students clarify the distinct causes and effects of each phenomenon.

Expansionary and Contractionary Monetary Policy
Students will analyze how the central bank uses monetary policy to combat recessions and inflation by adjusting interest rates and the money supply.
