| Lesson Topic: State and explain strategies to reduce the effects of these environmental issues, limited to: (a) climate change: planting trees, reduction in livestock farming, decreasing use of fossil fuels, increasing use of hydrogen and renewable energy, e.g. wi |
Learning Objective/s:
- Describe the chemical basis of climate change and acid rain.
- Explain at least five mitigation strategies for climate change, including tree planting, reduced livestock, fossil‑fuel reduction, hydrogen use and renewable energy.
- Explain three chemical mitigation methods for acid rain such as catalytic converters and flue‑gas desulfurisation.
- Compare the effectiveness of different strategies in lowering greenhouse‑gas or acid‑rain precursors.
- Evaluate how chemical principles underpin each mitigation approach.
|
Materials Needed:
- Projector and screen
- PowerPoint slides with diagrams
- Handouts containing the strategy tables
- Carbon‑cycle and FGD schematic printouts
- Whiteboard and markers
- Worksheet for group analysis
|
Introduction:
Begin with a striking image of a smog‑filled city and a thriving forest to highlight contrasting environmental impacts. Ask students to recall how combustion of fossil fuels produces CO₂, CH₄, SO₂ and NOₓ, linking to previous lessons on greenhouse gases and atmospheric chemistry. Explain that by the end of the lesson they will be able to state and justify specific chemical strategies that mitigate climate change and acid rain.
|
Lesson Structure:
- Do‑now (5’) – quick quiz on greenhouse gases and acid rain.
- Mini‑lecture (10’) – chemical mechanisms behind climate change and acid rain.
- Group analysis (15’) – examine provided tables of strategies and match each to its chemical benefit.
- Interactive simulation (10’) – use an online carbon‑cycle model to see the impact of tree planting and renewable energy.
- Case‑study discussion (10’) – evaluate catalytic converters and flue‑gas desulfurisation using reaction equations.
- Check for understanding (5’) – exit‑ticket: list two strategies for each issue and the chemical principle behind them.
|
Conclusion:
Summarise that mitigating climate change and acid rain relies on altering chemical reactions that generate or remove harmful gases. Students submit their exit‑ticket lists, reinforcing the key strategies discussed. For homework, assign a short research task to find a real‑world example of a renewable‑energy project or a flue‑gas scrubber and explain the chemistry involved.
