Overview

This 80-minute lesson engages lower-ability Year 8 students with essential concepts of global warming and human impact on the planet. It aligns closely with the National Curriculum for England geography standards, particularly G3.3 and G3.4, emphasising place-based learning and understanding physical and human geography processes.

---

National Curriculum Links

• G3.3 Physical Geography: Understanding climate change from the Ice Age to present, including weather and climate processes.
• G3.4 Human Geography: Understanding international development and how human activities affect natural systems and landscapes.
• Framework: Enables students to understand human-environment interaction and the significance of sustainable development.

---

Learning Objectives

By the end of the lesson, pupils will be able to:

• Explain what global warming is in simple terms (National Curriculum G3.3).
• Identify at least three causes of global warming linked to human activities (National Curriculum G3.4).
• Suggest practical actions individuals can take to help protect the planet (National Curriculum G3.4).
• Understand the interaction between human and physical geography in the context of climate change.

Resources

• Large interactive world map (physical and human features)
• Sets of coloured cards (causes, effects, solutions)
• Video clip: Simple explanation of global warming (approx. 4 minutes)
• Whiteboard and markers
• Plastic bottle, thermometer, ice cubes (for mini experiment)
• Worksheet: “Global Warming at a Glance” (diagram + questions)
• Sticky notes and pens

Lesson Structure

Starter (10 minutes) – Engage & Activate Prior Knowledge

Activity: Ice Cube & Bottle Experiment

• Fill a clear plastic bottle with some water and ice cubes, place a thermometer in the bottle.
• Ask students what happens to the ice over time and why.
• Explain that this models ice melting in colder places due to warming - like glaciers melting because of global warming.
• Prompt discussion: “What do you think global warming means?”

---

Introduction (15 minutes) – Define & Explain

Activity: Video & Interactive Discussion

• Show a short, age-appropriate video explaining global warming and its basic causes (greenhouse gases, carbon emissions).
• On the interactive map, point out examples of places affected by global warming (e.g., Polar Regions, forests, cities).
• Using whiteboard, create a simple mind map of what they learned:
  • What is global warming?
  • Causes? (e.g., cars, factories, deforestation)
  • Effects? (e.g., rising temperatures, ice melt)

---

Main Activity (35 minutes) – Explore Causes and Solutions

Part 1: Card Sorting (20 minutes)

• Each student receives a set of coloured cards labelled with causes (e.g., burning fossil fuels), effects (e.g., floods), and solutions (e.g., recycling).
• Working in pairs, they sort cards into these three categories, discussing their thoughts.
• Regroup and discuss as a class to correct misunderstandings.

Part 2: Place-Based Example Discussion (15 minutes)

• Present a case study: The UK experiencing hotter summers and flooding.
• Using the world map and local references, discuss how human actions in urban areas contribute to these changes.
• Ask: “How do rising temperatures affect people and places near you?”
• Link this to National Curriculum outcomes showing human and physical geography interaction.

---

Plenary (15 minutes) – Consolidate & Assess Understanding

Activity: Sticky Note Gallery

• Each student writes one thing they learned about global warming, one cause, and one action they can take on separate sticky notes.
• Stick notes on the board under headings: ‘Learned’, ‘Causes’, ‘Actions’.
• Quickly review common themes aloud.

Assessment:

• Use worksheet “Global Warming at a Glance” to check understanding.
• Include simple questions like:
  • What is global warming?
  • Name two causes.
  • What can people do to help?

---

Differentiation & Support

• Provide sentence starters for written tasks (e.g., “Global warming is...”, “One cause is...”).
• Use visuals and simple language throughout with repeated explanations.
• Encourage paired work to support peer learning and verbal expression.

---

Cross-Curricular Links

• Science: Understanding greenhouse gases and climate systems.
• PSHCE: Taking personal and community responsibility for the environment.
• English: Enhancing vocabulary on environmental issues and practising explanation skills.

---

Extension Ideas

• Investigate local energy use and produce a simple leaflet on reducing carbon footprint.
• Create a short role-play on conversations between nature and humans discussing climate change.

---

Teacher Notes

• Frequent checks for understanding are vital with lower-ability learners. Use questioning and encourage discussion.
• Foster a positive, solution-focused atmosphere to empower students about climate change rather than instill fear.
• Consider inviting a local environmental expert or arranging a virtual field trip to a nearby natural site affected by climate change for future lessons.
