Christchurch Earthquake Impacts

Overview

In today’s inquiry lesson, students investigate the effects of the Christchurch earthquake (2011) using a short “Impacts” video. They will practise Social Inquiry skills by asking questions, gathering evidence, and explaining how impacts affected people, places, and systems, with a focus on what can and cannot be predicted from hazard events.

Learning intentions

Students will:

• WALT conduct a short Social Inquiry into the impacts of the Christchurch 2011 earthquake.
• WALT identify key effects on people, places, and services using evidence from the video.
• WALT explain how responses and preparedness reduce harm (even though earthquake timing and strength are not predictable).
• WALT compare statements using a simple claim–evidence–reasoning structure.

Success criteria

Students can:

• I can list 3–5 impacts shown or implied in the video (written or spoken).
• I can match each impact to a piece of evidence from the video notes (what I saw/heard).
• I can write one clear paragraph using claim–evidence–reasoning.
• I can take part respectfully in group discussion and build on others’ ideas.

Curriculum links

• Social Inquiry: explore and explain events in society and environment by asking questions, gathering evidence, and making meaning.
• Year 8 Geography: Earthquakes and volcanic eruptions (effects and impacts; preparedness and planning).
• Key competencies: thinking (organising evidence), participating and contributing (discussion roles), and communicating (explaining impacts clearly).

Lesson structure (60 minutes)

1. 0–5 min · Hook (quick activate). Teacher displays the lesson question: “What impacts did the 2011 Christchurch earthquake have?” and briefly reminds students that not all details will be in the video. Students do a “thumb check” plus 1-minute quick write: “One word I associate with earthquakes is…”

2. 5–12 min · Direct teach: Social Inquiry steps. Teacher explains the inquiry routine: Question → Watch/Collect evidence → Sort impacts → Explain with claim–evidence–reasoning, using a board model with sentence starters. Students repeat the steps with a class chant and underline the sentence starters on their worksheet.

3. 12–24 min · Video viewing with guided note-catcher. Teacher plays the “Impacts” video. She pauses at set points to support low reading comprehension without needing extra tech. Students complete a note-catcher with the same headings: People / Places / Services / After-effects, and record short phrases (not full sentences). Support: teacher provides an illustrated word bank on the worksheet (e.g., homes, roads, emergency services, injuries, rebuilding, fear/stress, community support).

4. 24–30 min · Evidence check (language-light). Teacher calls out one heading at a time and reads a sample student response aloud (anonymous). Students “traffic light” their own notes: Green = I have evidence; Yellow = I’m unsure; Red = I need more from the video (they can add one phrase from the teacher recap).

5. 30–40 min · Group sorting: impacts vs. guesses. Students in groups of 4 use printed picture/label cards to sort: “Impact shown in video” and “Possible but not evidenced yet.” Teacher circulates with a short script: “What did the video show? What makes you think that?” Higher-capability students add an extra card: “Why this impact matters for planning.”

6. 40–52 min · Write an impacts explanation (scaffolded paragraph). Teacher models a one-paragraph answer on the board:

• Claim sentence (main impact)
• Evidence sentence (what the video showed—use their note-catcher phrases)
• Reasoning sentence (why it is an impact and how it affects preparedness) Students write their own paragraph using sentence starters and a word bank. ESOL support: allow sentence frames and highlight key words (impact, evidence, because, therefore). Capable students add a second paragraph sentence: “Preparedness actions help by…”

7. 52–58 min · Share and feedback (structured). Teacher uses a “Gallery Walk Speak” routine: students read their paragraph silently, then the group selects one to share orally (from the prepared paragraph, not free speech). Students listen and use a single feedback prompt: “I believe your claim because your evidence shows…”

8. 58–60 min · Exit ticket (quick assessment). Students complete: “One impact from the video was ___. My evidence was ___. This matters because ___.”

Resources

• Printed note-catcher (People / Places / Services / After-effects)
• Illustrated word bank for impacts and responses (NZ-context)
• Impact label/picture cards (for sorting)
• Claim–evidence–reasoning paragraph scaffold (sentence starters)
• Video speaker device and printed copies only (no student devices)
• Board model sheet (completed example paragraph)
• Coloured pencils/highlighters for traffic-light self-check

Assessment

• Formative during note-catcher completion: teacher checks if students record evidence phrases (not just opinions).
• Formative through sorting activity: teacher listens for correct “evidence vs guess” reasoning.
• Summative within-class: exit ticket assessed for claim–evidence–reasoning clarity.

Differentiation

• Provide sentence starters and optional sentence frames for ESOL students; reduce writing load to phrases first, then one paragraph sentence set.
• Offer a visual word bank and picture cards to lower reading demand while keeping academic thinking.
• Pre-teach one key idea: “Earthquake timing and strength are not predictable, so planning matters.”
• Challenge capable students with an extra requirement: include one link to preparedness/planning (“This affects how people prepare because…”).

Extension (optional)

• If time remains, ask students to add one “What I would include in a preparedness plan” item based on their evidence from the video (1–2 sentences).
