Subject: Geography
Lesson Topic: Global warming and climate change: evidence, causes, greenhouse gases, physical and human factors
Learning Objective/s:
  • Describe three key pieces of evidence that demonstrate recent global warming.
  • Explain natural versus anthropogenic causes of climate change and identify the major greenhouse gases.
  • Analyse how physical factors (solar radiation, albedo, atmospheric circulation) and human activities influence the climate system.
  • Evaluate the principal impacts of climate change on physical and human systems.
  • Propose mitigation and adaptation strategies and justify their effectiveness.
Materials Needed:
  • Projector or interactive whiteboard
  • PowerPoint/Google Slides presentation with diagrams and GHG table
  • Printed worksheet with evidence checklist and cause‑effect chart
  • World map or climate data charts
  • Markers and sticky notes for group work
  • Laptop for teacher‑led video clips
 Introduction:
Begin with a striking image of melting glaciers and ask students what they think is causing the change. Connect to prior knowledge of the water cycle and energy balance from earlier lessons. State that by the end of the lesson they will be able to identify evidence of warming, explain its causes, and outline mitigation options.
Lesson Structure:
  1. Do‑now (5’) – Students match climate‑change evidence statements to images displayed on the board.
  2. Mini‑lecture (15’) – Present global warming evidence and the greenhouse‑gas table using slides.
  3. Guided inquiry (20’) – In pairs, analyse a case study (e.g., Arctic sea‑ice loss) and fill a cause‑effect chart distinguishing natural and human factors.
  4. Concept mapping (10’) – Whole‑class create a mind map of physical vs human factors influencing climate.
  5. Impact & response discussion (10’) – Groups list local impacts and propose one mitigation and one adaptation measure; share findings.
  6. Check for understanding (5’) – Quick quiz (Kahoot or exit ticket) with three key questions.
  7. Recap & homework brief (5’) – Summarise key points and assign a short research task on a local climate‑change impact.
Conclusion:
Summarise how evidence, causes, and factors interrelate and why they matter for future decisions. Ask students to write one takeaway on an exit ticket and hand it in. For homework, students research a local climate‑change impact and suggest a feasible mitigation strategy.
