Exploring megacities

Overview

In this lesson (Lesson 4 of 16), students use physical and case-study evidence to identify key challenges of megacities and explain how these challenges affect liveability and environmental health. Students practise recognising perspectives of people or organisations on a geographical issue.

Learning intentions

• Students will identify challenges faced by megacities using a case study and images.
• Students will describe how patterns of urban inequality can affect liveability and environmental health.
• Students will identify different perspectives of people or organisations about a geographical issue.
• Students will use geographical terminology to communicate findings clearly.

Success criteria

• I can name at least two megacity challenges shown in the case study and images.
• I can explain how inequality influences liveability (e.g. housing, health, access to services).
• I can identify at least two perspectives (e.g. resident group, government, NGO, business).
• I can communicate my analysis using geographical terms (e.g. liveability, inequality, access, services, environmental health).

Curriculum links

• GELS-PER-01: Students identify perspectives of people or organisations on a geographical issue.
• GELS-TAP-02: Students use geographical tools for inquiry (including interpreting images and selecting relevant evidence).
• GELS-COM-01: Students communicate information using geographical terminology.

Lesson structure (60 minutes)

1. 0–5 min · Hook. Teacher shows two contrasting printed photos of megacity neighbourhoods (one with better housing/green space and one with poorer conditions/less open space) and asks: “What might be happening to people’s health and wellbeing in each place?”

• Students quick-write 2 observations and 1 question they have about each photo.

2. 5–15 min · Mini-case study input. Teacher introduces the unit focus: megacities and liveability, then models an evidence-based claim using one short, teacher-provided case-study summary (no links).

• Students complete a guided template: “Challenge → Evidence from case study → Possible impact on liveability.”

3. 15–30 min · Image interpretation gallery. Students rotate through 4 stations with physical photos (urban inequality indicators such as housing quality, transport access, green space, waste issues, air/pollution cues).

• At each station, students annotate the image with: “I notice… / This suggests… / This could impact…”
• Teacher circulates and prompts students to link evidence to liveability and environmental health.

4. 30–42 min · Perspectives carousel. Teacher gives each student (or pair) a role card: resident (different income group), local government planner, health professional, environmental NGO, or business representative.

• Students select one station’s evidence and complete a “Perspective chart”:
• “My perspective is…”
• “I notice…”
• “I care most about…”
• “I propose…”
• Teacher prompts: “What might be missing from your viewpoint? Who else would see the issue differently?”

5. 42–52 min · Whole-class synthesis. Students share one challenge and one perspective using a structured sentence frame: “A key challenge is… Evidence shows… From the perspective of…, the priority is…”

• Teacher records challenges on the board in a simple two-column structure: “Liveability impacts” vs “Environmental health impacts.”

6. 52–58 min · Formative check (short exit task). Students complete a 4-sentence written response:

• 1 sentence: Identify a challenge.
• 1 sentence: Explain an impact on liveability.
• 1 sentence: Explain an impact on environmental health.
• 1 sentence: Identify a perspective and its priority.
• Teacher collects responses for feedback.

7. 58–60 min · Pack-up and transition. Teacher previews next lesson’s focus (how communities can improve liveability).

• Students place photos and templates into the unit folder and tidy station materials.

Resources

• Printed photo set (4 stations) showing urban inequality cues (housing, green space, transport access, waste/pollution indicators)
• Role cards (resident groups, government, NGO, health professional, business)
• Case-study summary handout (teacher-provided text)
• “Challenge → Evidence → Impact” guided template
• “Perspective chart” worksheet
• “Notice / Suggests / Impact” annotation sheets
• Projector/board or chart paper for whole-class synthesis
• Coloured pencils or highlighters for annotation

Assessment

• Formative: observation during gallery work (checking evidence-to-impact links and use of terminology).
• Formative: teacher checks “Perspective chart” for accuracy (recognising perspectives and priorities).
• Summative-in-mini: exit task (4 sentences) collected and used to identify common misconceptions (e.g. confusing liveability with environmental health, or missing evidence).

Differentiation

• Support: provide sentence starters and word bank (liveability, access, services, inequality, environmental health, wellbeing, pollution, housing, transport).
• Support: allow pairs to share roles and co-write the perspective chart; offer a partially completed template for students needing extra structure.
• Extension: challenge students to compare two stations and argue which challenge is most urgent, using at least two pieces of evidence.
• EAL/SEN: use visual cues on templates (icons for “evidence” and “impact”); allow oral rehearsal before writing; check that students can explain concepts in simple language before formal sentences.
• Behavioural/organisational: assign clear station routines (timekeeper, role for each partner) to reduce task switching and improve on-task engagement.
