Classifying Natural Resources
Differentiate between renewable, non-renewable, and flow resources in the Canadian context.
Key Questions
- Explain the key characteristics that define renewable, non-renewable, and flow resources.
- Analyze examples of each resource type found in Canada.
- Differentiate the sustainability challenges associated with each resource category.

About This Topic
Natural resources are the foundation of Canada's economy and identity. This topic introduces the three main categories of resources: renewable (can be replaced by natural processes, like forests), non-renewable (exist in limited amounts and cannot be replaced, like oil), and flow resources (must be used when and where they occur, like wind and sunlight). Students will explore how Canada's vast geography provides an abundance of these resources and the challenges of managing them sustainably.
The curriculum emphasizes the importance of moving toward more sustainable resource use to protect the environment for future generations. Students will analyze the economic benefits of resource extraction alongside the environmental and social costs. This topic is best taught through 'sorting' activities and collaborative investigations into the resources used in everyday products.
Active Learning Ideas
Sorting Activity: Resource Categories
Students are given a list of 20 Canadian resources. They must work in pairs to categorize them as renewable, non-renewable, or flow, and then rank them by their importance to their local community.
Inquiry Circle: The Life of a Product
Groups choose a common item (e.g., a smartphone or a pencil) and research all the natural resources required to make it. They create a 'resource map' showing where these materials come from.
Think-Pair-Share: What is 'Sustainable'?
Students brainstorm a definition of sustainability. They share examples of how a renewable resource (like fish) could become non-renewable if it is not managed correctly.
Watch Out for These Misconceptions
Common MisconceptionRenewable resources will never run out.
What to Teach Instead
Renewable resources can be exhausted if they are used faster than they can regenerate (e.g., overfishing). A 'fishing game' simulation with limited regrowth can quickly correct this belief.
Common MisconceptionFlow resources are the same as renewable resources.
What to Teach Instead
While both are sustainable, flow resources like wind or tides cannot be 'stored' in their natural state like a forest can. Using a 'storage vs. immediate use' comparison can help clarify the difference.
