Defining Sustainability & Development

Active learning works for this topic because sustainability is a systems-thinking concept that requires students to analyze relationships between economic, ecological, and social factors. Hands-on activities help students move beyond abstract definitions to understand how these factors interact in real-world contexts.

• Grade 12
• Geography
• 3 activities
• 30 min–90 min

Learning Objectives

1. Critique the historical evolution of sustainability definitions, identifying key shifts in focus.
2. Compare and contrast weak and strong sustainability models, citing specific examples of each.
3. Explain the principle of intergenerational equity and its application in sustainable development frameworks.
4. Analyze the challenges posed by globalization to achieving environmental and social sustainability.
5. Synthesize information from diverse sources to propose solutions for local sustainable development issues.

Simulation Game

⏱ 90 min·Small Groups

Simulation Game: The Sustainable City Design

Groups are given a 'brownfield' site in a city and must design a mixed use development that incorporates renewable energy, public transit, and green space. They must present their plan to a 'city council' and explain how it meets the UN Sustainable Development Goals.

Prepare & details

Explain the concept of 'intergenerational equity' within the framework of sustainable development.

Facilitation Tip: During the Sustainable City Design simulation, circulate and ask guiding questions like, 'Which group’s model best balances the three pillars of sustainability?' to prompt critical reflection.

Setup: Flexible space for group stations

Materials: Role cards with goals/resources, Game currency or tokens, Round tracker

Think-Pair-Share

⏱ 30 min·Pairs

Think-Pair-Share: Indigenous Stewardship

Students read a case study of an Indigenous led conservation project (e.g., Indigenous Protected and Conserved Areas). They discuss how this approach differs from a traditional 'national park' model and share their thoughts on the benefits of each.

Prepare & details

Compare and contrast different models of sustainable development (e.g., weak vs. strong sustainability).

Facilitation Tip: For the Think-Pair-Share on Indigenous Stewardship, assign roles (e.g., researcher, listener, presenter) to ensure equitable participation.

Setup: Standard classroom seating; students turn to a neighbor

Materials: Discussion prompt (projected or printed), Optional: recording sheet for pairs

Gallery Walk

⏱ 40 min·Whole Class

Gallery Walk: Sustainability Innovations

The teacher displays info on various technologies like vertical farming, carbon capture, and circular fashion. Students move through the gallery, 'voting' with sticky notes on which innovation has the highest potential for global impact and why.

Prepare & details

Critique the challenges of achieving true sustainability in a globalized economy.

Facilitation Tip: When facilitating the Gallery Walk, place a small whiteboard at each station for students to post questions or comments that peers can respond to in real time.

Setup: Wall space or tables arranged around room perimeter

Materials: Large paper/poster boards, Markers, Sticky notes for feedback

Teaching This Topic

Teach this topic by grounding abstract concepts in concrete examples from students’ communities or the news. Avoid presenting sustainability as a binary (achievable or impossible) but instead frame it as a spectrum of practices and trade-offs. Research shows that using case studies helps students grasp the complexity of integrating economic, ecological, and social goals.

What to Expect

Successful learning looks like students applying the triple bottom line to analyze development models and articulating nuanced arguments about sustainable development. Students should also demonstrate the ability to differentiate between weak and strong sustainability and provide evidence-based reasoning for their positions.

Watch Out for These Misconceptions

Common Misconception

During the Sustainable City Design simulation, watch for students focusing exclusively on environmental features. Redirect them by asking, 'How will your city support economic activities and social equity while protecting the environment?'.

What to Teach Instead

Use the 'three-legged stool' model during the simulation debrief. Have students identify which leg of their city’s stool is most fragile and brainstorm how to strengthen it.

Common Misconception

During the Think-Pair-Share on Indigenous Stewardship, watch for students equating sustainability solely with Indigenous practices. Redirect by asking, 'How might Indigenous stewardship principles be integrated into modern urban planning?'.

What to Teach Instead

Use the Think-Pair-Share structure to explicitly compare Indigenous stewardship with other sustainability models. Ask students to identify shared values and differences in approach.

Assessment Ideas

Discussion Prompt

After the Sustainable City Design simulation, pose the question: 'Is your city an example of weak or strong sustainability? Support your answer with evidence from your design and at least two vocabulary terms.'

Exit Ticket

After the Gallery Walk, provide students with a scenario describing a new development project (e.g., a solar farm or a shopping mall). Ask them to write one paragraph explaining whether the project aligns more with weak or strong sustainability, and one sentence on how intergenerational equity is affected.

Quick Check

During the Think-Pair-Share on Indigenous Stewardship, display a list of statements related to sustainability definitions. Ask students to identify each statement as representing weak sustainability, strong sustainability, or neither. Follow up by asking students to explain their reasoning for one statement to a peer.

Extensions & Scaffolding

• Challenge students who finish early to design a policy brief advocating for a specific sustainability innovation featured in the Gallery Walk.
• Scaffolding: Provide a graphic organizer with sentence stems for the Think-Pair-Share to support students in structuring their arguments around Indigenous stewardship.
• Deeper exploration: Invite a guest speaker (e.g., an urban planner or Indigenous knowledge keeper) to discuss how systemic change is implemented in practice.

Key Vocabulary

Sustainable Development	Development that meets the needs of the present without compromising the ability of future generations to meet their own needs. It balances economic, social, and environmental considerations.
Intergenerational Equity	The concept that future generations should have the same or better opportunities and resources as the present generation. It is a core principle of sustainable development.
Weak Sustainability	A perspective that allows for the substitution of natural capital with manufactured capital, suggesting that technological innovation can compensate for environmental degradation.
Strong Sustainability	A perspective that emphasizes the non-substitutability of natural capital. It argues that natural resources and ecological systems have intrinsic value and cannot be fully replaced by human-made capital.
Traditional Ecological Knowledge (TEK)	A cumulative body of knowledge, practice, and belief, evolving by adaptive processes and handed down through generations by cultural transmission, about the relationship of living beings (including humans) with one another and with their environment.
