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.
- On a world map, where are most earthquakes and volcanoes found? (in long belts along the edges of Earth's plates / only near the North Pole / only in the middle of continents / scattered evenly everywhere) → in long belts along the edges of Earth's platesPrompt: Earth's outer layer is broken into huge moving pieces.
- True or false? The ocean floor is completely flat. (True / False) → FalsePrompt: Where do plates meet, and what forms there?
- How did this feature form: Iceland's rift valley? (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 volcanic eruptions? (monitoring gas and ground movement, and evacuation plans / ocean sensors, warning sirens and signposted routes to high ground / retaining walls, drainage and planting on slopes / buildings with flexible frames and shock-absorbing bases) → monitoring gas and ground movement, and evacuation plansPrompt: What does each hazard do: shake, flood from the sea, erupt, or slide?
- Scientists cannot stop a volcano erupting. What CAN they do? (move the volcano / cool the magma with ice / watch for warning signs and help people leave in time / plug the top with concrete) → watch for warning signs and help people leave in timePrompt: Before eruptions, the ground may swell and gases may change.
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.
- Which solution best reduces harm from landslides? (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 / monitoring gas and ground movement, and evacuation plans) → retaining walls, drainage and planting on slopesPrompt: What does each hazard do: shake, flood from the sea, erupt, or slide?
- True or false? A tsunami is caused by strong wind. (True / False) → FalsePrompt: We cannot stop these hazards. What can we do?
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.
