1 Lesson Goals
A modern earthquake-resistant house with reinforced design

By the end of this lesson, I will be able to:

  • understand the main ideas and key details in Earthquake-Resistant Design.
  • learn and use important vocabulary from the lesson.
  • use the lesson language in speaking or writing.
Start here: What do you already know about this topic? Tell a partner one idea.
2 Reading
Before you read:

Look at the title. What do you already know about this topic? Write two ideas, then compare with a partner.

In earthquake-prone countries, engineers cannot prevent the ground from shaking, but they can reduce the chance that buildings collapse. One important principle is flexibility. A structure that can move slightly may absorb energy better than a very rigid structure that cracks under sudden force. Steel frames and flexible joints are therefore common in modern earthquake-resistant design.

Base isolation is another technique. Special bearings or pads are placed between a building and the ground so that some ground movement is not transferred directly into the structure. Engineers also study how weight and forces travel through a building. Computer simulations can show where stress may concentrate, allowing weak points to be strengthened before construction begins.

Older buildings may need retrofitting. This can involve adding stronger connections, reinforcing walls or improving foundations. Engineers also need to think beyond individual buildings. Hospitals, roads, bridges and water systems must remain usable after a major earthquake so that emergency services can operate. Sensors inside modern structures now provide real-time data during earthquakes, helping engineers learn how buildings actually behave and improve future designs.
3 Vocabulary
Key words: seismic · flexibility · isolation · retrofitting · foundation

Write a short meaning or synonym for each word.

seismic –

flexibility –

isolation –

retrofitting –

foundation –

4 Check Your Understanding

1. Why can flexibility help a building?

2. What is the purpose of base isolation?

3. How do simulations help before construction?

4. Why is retrofitting important?

5. Which community systems need to remain usable after an earthquake?

5 Language Focus

Complete each sentence with because, therefore or as a result.

1. The building can move slightly; , less force may be transferred to rigid parts.

2. Old buildings may not meet modern standards; they may need retrofitting.

3. Base isolators reduce transferred movement they separate the structure from some ground motion.

4. Sensors collect real-time data; engineers can study actual building behaviour.

6 Listen & Speak

Listen

Listen to your teacher. You will hear the text twice. Answer the questions.

1. When do engineers inspect buildings?

2. Name two signs they check.

3. Why can appearance be misleading?

4. What may still be required?

Speak

Discuss with a partner or small group.

• Which buildings should receive the highest earthquake-safety priority?
• Is it better to strengthen an old building or replace it?
• What could people learn from sensors inside buildings?

7 Use Your English

Something New

Draw a simple building with three earthquake-safety features. Present it to a partner, who asks one “What if?” question about your design.

Write

Write 150–180 words explaining how engineers can make buildings and communities more resilient to earthquakes.

8 Puzzle or Game
Vocabulary Detective

Choose four words from the Vocabulary panel. Write a short clue for each word without writing the word itself. Swap with a partner and see how many you can guess.

Bonus: Use one of the words in a new sentence.

9 Success Criteria ✓

Tick each statement when you can do it.

  • I can explain the main idea of the lesson.
  • I can use at least three new words correctly.
  • I can complete the language task.
  • I can share an idea in spoken or written English.

One thing I am proud of today:

10 Show What You Can Do
Final challenge: Earthquake-Resistant Design

Plan: Note your strongest idea, 3 useful words or phrases, and one supporting detail from the lesson.

Respond: Write a short paragraph of 6–8 sentences, or prepare a 45-second spoken response, showing what you learned.

Reflect: Underline the part of your response that best shows your progress.
