Earthquake Impact Analysis

Lesson Overview

Year Level: Year 5
Subject: Science
Unit: Shaking the Earth: Tectonics
Lesson Number: 5 of 6
Lesson Duration: 45 minutes
Curriculum Link:
This lesson aligns with the Australian Curriculum (v9.0) - Science:

• AC9S5U03: Describe how sudden geological changes and extreme weather events can affect Earth’s surface.
• AC9S5I02: Compare methods and findings from investigations and evaluate the fairness of results.

Lesson Objectives

By the end of this lesson, students will:

1. Understand the impacts of earthquakes on communities, including damage to human structures and the environment.
2. Analyse real-world earthquake events and their consequences.
3. Engage in a hands-on group activity to explore earthquake-resistant design principles.
4. Reflect on ways communities can prepare for earthquakes.

Lesson Structure

Introduction (10 minutes) – Discussion & Engagement

1. Class Poll - "What Would Happen?"

   • Display an image of a city with large buildings and ask:
     "What do you think would happen if a powerful earthquake shook this city?"
   • Record students' responses on the whiteboard to assess prior knowledge.

2. Quick Recap (Teacher-led talk) – 3 minutes

   • Revisit key points from previous lessons:
     • What tectonic plates are.
     • How earthquakes occur.
   • Lead discussion:
     • "What happens to buildings, roads, and people during an earthquake?"

3. Introduce Today's Focus (2 minutes)

   • Explain that today’s lesson will examine real earthquakes and how they affect communities.

Main Activity (25 minutes) – Case Study & Hands-On Challenge

1. Case Study Analysis (10 minutes) – Real-World Problem Solving

Students investigate two real earthquakes:

• 2011 Christchurch Earthquake (New Zealand) – A Nearby Example
• 2023 Turkey & Syria Earthquake – Large Scale Destruction

Activity:

• Students work in pairs and study printed impact sheets of each earthquake.

• Each pair answers:

  1. What happened to buildings, roads, and the environment?
  2. How were people and emergency services affected?
  3. How did people prepare or recover?

• Class Discussion: Groups share findings, comparing earthquake impacts in different regions.

2. Hands-on "Shake Test" Challenge (15 minutes) – Engineering & Problem Solving

• Each group of 4 students builds a small structure using LEGO or toothpicks & marshmallows.
• The Challenge: The structure must withstand an "earthquake simulation" (gentle shaking of the table).
• After testing, groups discuss:
  • What worked?
  • What failed?
  • How could we strengthen buildings?

Conclusion & Reflection (10 minutes) – Real-World Connections

1. Exit Ticket Question (5 minutes) – Personal Reflection

   • Students write one short answer to:
     "How can communities prepare for earthquakes?"

2. Teacher Wrap-Up (5 minutes)

   • Summarise key points:
     • Earthquake impacts on buildings, people, and infrastructure.
     • Importance of strong building design and emergency response.
   • Lead into next lesson:
     • "Next lesson, we’ll explore how people predict and prepare for earthquakes!"

Assessment & Differentiation

Assessment Opportunities

• Class Discussion & Participation: Assess engagement and understanding of earthquake impacts.
• Group Work: Observe teamwork in case study analysis and hands-on activity.
• Exit Ticket: Use responses to gauge individual understanding.

Differentiation Strategies

• Support for struggling students: Provide sentence starters for discussion and extra guidance during the shake test.
• Extension for advanced learners: Encourage research into Australian earthquake-resistant architecture.
