Mitigation Strategies for Climate Change

Active learning works here because climate mitigation requires students to grapple with trade-offs between technical, economic, and political factors. Through structured tasks, they connect abstract data about renewables and policies to real-world implications like infrastructure costs and international cooperation.

Activity 01

• Jigsaw
• 45 min · Small Groups

Jigsaw: Comparing Renewables

Assign each small group one renewable source (solar, wind, hydro, geothermal). They research emission reduction data, costs, and Singapore suitability using provided sources. Groups then teach peers and co-create a class comparison chart.

Compare the effectiveness of different renewable energy sources in reducing carbon emissions.

Facilitation Tip

For the Jigsaw, assign each renewable energy source to expert groups first, then mix students to present findings in mixed teams before ranking options by efficiency and cost data.

What to look for

Present students with a short case study of a hypothetical nation's energy sector. Ask them to identify two potential renewable energy sources suitable for that nation and explain one advantage and one disadvantage of each for reducing emissions.

Activity 02

• Morning Circle
• 50 min · Small Groups

Policy Simulation: Emission Reduction Framework

In small groups, students act as a national task force. They review case studies, propose incentives like subsidies or taxes, and present frameworks to the class for peer feedback and vote.

Evaluate the role of international agreements in achieving global climate targets.

Facilitation Tip

During the Policy Simulation, provide a clear timeline for negotiations and require teams to justify their carbon tax proposals with projected emission reductions.

What to look for

Facilitate a class debate on the statement: 'International agreements are the most effective tool for mitigating climate change.' Prompt students to support their arguments with specific examples of treaties and their outcomes, considering national sovereignty and differing economic capacities.

Activity 03

• Formal Debate
• 35 min · Pairs

Formal Debate: Paris Agreement Impact

Pairs prepare arguments for and against the agreement's effectiveness. Hold a structured debate with evidence from emission trends, then class discusses alternatives like stronger binding targets.

Design a national policy framework to incentivize carbon emission reductions.

Facilitation Tip

In the Debate, assign roles (e.g., negotiator, economist, environmental justice advocate) to ensure balanced arguments and push students beyond surface-level positions.

What to look for

On an index card, have students define 'carbon capture and storage' in their own words and list one industry in Singapore where this technology could be applied to reduce emissions.

Activity 04

• Morning Circle
• 30 min · Pairs

Model: Carbon Capture Demo

Pairs build simple models using bottles and chemicals to simulate capture. Record efficiency factors, discuss scalability challenges, and link to real Singapore pilots.

Compare the effectiveness of different renewable energy sources in reducing carbon emissions.

Facilitation Tip

For the Carbon Capture Demo, pre-set up the materials with clear visuals of CO2 flow so students focus on analyzing efficiency metrics rather than assembly.

What to look for

Present students with a short case study of a hypothetical nation's energy sector. Ask them to identify two potential renewable energy sources suitable for that nation and explain one advantage and one disadvantage of each for reducing emissions.

A few notes on teaching this unit

Approach this topic by balancing technical content with real-world complexity. Avoid oversimplifying transitions to renewables or framing carbon capture as a silver bullet, as both can lead to misconceptions. Instead, use local Singapore examples like the Green Plan 2030 to anchor discussions in tangible policy targets and timelines. Research suggests students retain mitigation concepts best when they analyze trade-offs through role-play or data-driven activities, so prioritize structured comparisons over lectures.

Successful learning looks like students critically comparing energy technologies while recognizing systemic constraints, articulating policy trade-offs through simulation outcomes, and evaluating collective versus individual responsibility in mitigation strategies.

Watch Out for These Misconceptions

• During the Jigsaw activity, watch for students assuming renewables can replace fossil fuels overnight without addressing grid reliability or storage costs.

  Use the expert groups to highlight intermittency data in their presentations, then require mixed teams to calculate backup power needs using local Singapore consumption patterns.

• During the Model Carbon Capture Demo, watch for students concluding that capture technologies eliminate the need for emission reductions.

  Have students calculate the energy penalty of capture systems by comparing pre- and post-capture efficiency numbers provided in the demo materials, then discuss why this offsets only some emissions.

• During the Debate Paris Agreement Impact, watch for students dismissing global agreements as ineffective due to national self-interest.

  Prompt teams to reference specific clauses in the Paris Accord (e.g., Nationally Determined Contributions) and evaluate their enforceability using the simulation’s policy tools.
