White Island Hazards

Overview

In this lesson, students investigate the hazards associated with the White Island (Whakaari) volcano and how communities manage and protect places and environments. This builds on Lesson 12 by moving from identifying hazards and landform processes to explaining real-world environmental change and management.

Learning intentions

Students will:

• describe how places and environments change using evidence from the White Island case study
• identify hazards associated with a volcano (e.g. eruption, toxic gases, ash fall, lahars/landslides)
• explain how people manage and protect places and environments before, during and after hazards
• connect hazard risk to outcomes for people and the environment

Success criteria

Students can:

• list hazards and explain what could happen and who/what is affected
• use geographic language (hazard, risk, impact, management) in a short explanation
• identify at least two management strategies and justify how they reduce harm
• complete a case-study summary that is clear, sequenced and evidence-based

Curriculum links

• GELS-MAN-01: Students demonstrate ways to manage and protect a place or environment
• GELS-PRI-01: Students describe how places and environments change
• GELS-APC-02: Students identify ways in which Aboriginal Peoples care for and manage Country (considered through respectful land stewardship and place knowledge)
• Thinking and working geographically: students use evidence, spatial and cause–effect reasoning to communicate findings

Lesson structure (60 minutes)

1. 0–5 min · Hook. Teacher displays 2 images of White Island before/after the eruption and asks: “What dangers might be linked to a volcano even when it looks quiet?” Students do a quick think-pair-share and record one idea.

2. 5–12 min · Activate knowledge (mini-recall). Teacher revisits key terms from prior lessons: hazard vs risk vs impact, and briefly models a cause–effect sentence. Students complete a 3-sentence prompt: “A volcanic hazard can…; This increases risk for…; If it happens, impacts include…”

3. 12–25 min · Case study evidence jigsaw. Teacher assigns groups of 4–5 and gives each group a short set of case-study information cards (no links) covering hazards, triggers/signs, impacts, and management actions. Students read, highlight evidence, and create a “Hazard → Impact → Management” chart for their card set.

4. 25–38 min · Whole-class synthesis (create a class risk map). Teacher draws a simple class diagram with White Island in the centre and three layers around it: “Hazard”, “Impacts”, “Management”. Each group contributes one hazard and one management strategy; teacher checks accuracy and prompts with: “How does this reduce harm? What limitation might it have?” Students update their charts using the class model.

5. 38–52 min · Students write an explanation (structured). Teacher distributes a paragraph scaffold:

• Topic sentence naming the hazard context
• 2 body sentences: hazard and likely impacts (cause–effect)
• 1 body sentence: management strategies and how they protect people/environment
• Closing sentence: one evaluation (e.g. “This strategy is effective because…, but it may not prevent…”) Students write independently, then exchange with a partner for a brief “checklist swap” (geographic terms used correctly; evidence mentioned; management linked to reducing harm).

6. 52–58 min · Share and refine. Teacher invites 2–3 volunteers to share a key line; class provides one “glow” (what’s strong) and one “grow” (what to improve). Students revise one sentence in their paragraph.

7. 58–60 min · Exit ticket. Students answer: “Name one hazard at White Island and explain one management action that reduces risk.” Teacher collects for quick formative assessment.

Resources

• Case-study information cards (hazards, impacts, timelines, management responses)
• Class diagram template: Hazard / Impacts / Management
• Student vocabulary list: hazard, risk, impact, management, mitigation, before/during/after
• Paragraph scaffold worksheet
• Highlighters/coloured pencils
• Exit ticket slips
• Projector or display for hook images (printed or digital)

Assessment

• Formative during jigsaw: teacher circulates, checks hazard→impact reasoning and correct terminology use
• Formative during synthesis: teacher listens for explanations that link management to reduced harm
• Exit ticket: one hazard + one management action with an explanation (assesses alignment to GELS-PRI-01 and GELS-MAN-01)
• Pair checklist during writing: verifies students can communicate geographic understanding clearly

Differentiation

• Provide sentence starters and a word bank for students needing support (e.g. “A likely impact is…”, “This management strategy reduces risk by…”)
• Offer an annotated model paragraph for students who benefit from seeing a high-quality example
• Challenge extension-ready students with an “evaluate” requirement: add a final sentence about limitations or trade-offs (e.g. access restrictions vs tourism impacts)
• For EAL learners: allow bilingual dictionaries, pre-teach 5–7 key words, and use colour-coding to connect hazard types to impacts
• For students requiring additional scaffolding: reduce to two hazards and one management strategy, then build complexity after conferencing
• Group roles in jigsaw (reader, summariser, evidence finder, communicator) to ensure all students contribute
