Reduce the impact of earthquakes, volcanoes and tsunamis
Earth and rocks
CCSS NGSS.4-ESS3-2England: KS2 Geography links
Objective and success criteria
Students will: Reduce the impact of earthquakes, volcanoes and tsunamis.
- I can answer questions on today's skill on my own, without help.
- I can explain each step and say why it works.
- I can check my answer and spot a mistake.
Before and after
Needs first: Patterns on maps: mountains, volcanoes and earthquakes
Leads to: the next skill in this area.
Materials: Rock samples, Hand lenses, Mini whiteboards, A diagram or short video clip of the idea, Printed student sheet (below).
Warm-up · 6 min
- Quick retrieval from earlier learning (Patterns on maps: mountains, volcanoes and earthquakes). Students answer on mini whiteboards.
- Show answers together and note who needs support in the main task.
- Where is the deepest part of the ocean? (next to every beach / in a trench where one plate dives under another / in the middle of a calm bay / under the North Pole) → in a trench where one plate dives under anotherPrompt: The Mariana Trench is about 11 km deep.
- True or false? Mountain ranges often form where plates push together. (True / False) → TruePrompt: Where do plates meet, and what forms there?
- How did this feature form: the Mid-Atlantic Ridge? (formed where plates push together / formed where plates pull apart) → formed where plates pull apartPrompt: Is it a high mountain range or deep trench, or a crack and ridge where new rock appears?
Hook · 6 min
- Pass round different rocks and ask how each one might have formed.
- Share the objective: Reduce the impact of earthquakes, volcanoes and tsunamis. Read the success criteria together.
I do: model it · 12 min
- Work through the example out loud, saying why you do each step, not just what you do.
- Example: Which solution best reduces harm from earthquakes?
- Step 1: So the answer is: buildings with flexible frames and shock-absorbing bases
- Answer: buildings with flexible frames and shock-absorbing bases
- Pause after each step and ask a student to say what comes next.
We do: guided practice · 12 min
- Do these together. Students try each step on whiteboards before you reveal it.
- Use the hints as prompts rather than giving the answer.
- Which solution best reduces harm from earthquakes? (monitoring gas and ground movement, and evacuation plans / retaining walls, drainage and planting on slopes / ocean sensors, warning sirens and signposted routes to high ground / buildings with flexible frames and shock-absorbing bases) → buildings with flexible frames and shock-absorbing basesPrompt: What does each hazard do: shake, flood from the sea, erupt, or slide?
- Why do people practise earthquake drills like "Drop, Cover and Hold On"? (Because earthquakes happen every day everywhere. / So everyone knows how to protect themselves quickly during shaking. / To predict the exact time of the next earthquake. / To make earthquakes smaller.) → So everyone knows how to protect themselves quickly during shaking.Prompt: There is little time to think during an earthquake.
You do: independent practice · 17 min
- Students work on the student sheet. Circulate and check the first two answers of every student early.
- Students who finish: write a question of their own for a partner, with the answer.
The 8 questions are on the student sheet below, with answers in the key.
Exit ticket · 7 min
- Two questions on their own. Sort answers into got it / nearly / not yet to plan the next lesson.

Watch out for
- Everyday meanings of words getting in the way of the science meaning: define key words explicitly.
- Remembering facts without the reason: ask "why?" and "what is the evidence?"
Support and stretch
Support
- Review first: Patterns on maps: mountains, volcanoes and earthquakes.
- Use concrete materials: rock samples.
- Give the first step of each question, or a partly worked example to finish.
- Pair with a confident partner for the guided practice.
Stretch
- Explain a common mistake in writing and how to fix it.
- Write a word problem that uses today's skill, then solve a partner's.
