Objective and success criteria
Students will: Oceans, seas, lakes, rivers and ponds.
- 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: Land and water on Earth
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 · 4 min
- Quick retrieval from earlier learning (Land and water on Earth). Students answer on mini whiteboards.
- Show answers together and note who needs support in the main task.
- In which form is water found at the top of very high mountains? (there is never water there / only gas / solid ice and snow / only liquid) → solid ice and snowPrompt: It is very cold high up.
- About 96.5% of Earth's water is salt water. What percentage is fresh water? → 3.5 %Prompt: All the water together is 100%.
- Which landform is described: land that rises steeply far above its surroundings? (mountain / valley / island / river) → mountainPrompt: Is it high land, low land, land in water, or moving water?
Hook · 3 min
- Pass round different rocks and ask how each one might have formed.
- Share the objective: Oceans, seas, lakes, rivers and ponds. Read the success criteria together.
I do: model it · 7 min
- Work through the example out loud, saying why you do each step, not just what you do.
- Example: Which body of water is this: the largest body of salt water, covering huge parts of Earth?
- Step 1: So the answer is: ocean
- Answer: ocean
- Pause after each step and ask a student to say what comes next.
We do: guided practice · 6 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 body of water is this: a large area of salt water, partly surrounded by land? (waterfall / sea / river / pond) → seaPrompt: Is it salty or fresh? Moving or still? Big or small?
- Which of these usually holds the LEAST water? (a pond / a lake / a puddle) → a puddlePrompt: Order them from smallest to largest in your head.
You do: independent practice · 7 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 6 questions are on the student sheet below, with answers in the key.
Exit ticket · 3 min
- Two questions on their own. Sort answers into got it / nearly / not yet to plan the next lesson.
- Which of these usually holds the LEAST water? (an ocean / a puddle / a pond) → a puddlePrompt: Order them from smallest to largest in your head.
- Which body of water is this: a large area of salt water, partly surrounded by land? (waterfall / river / sea / lake) → seaPrompt: Is it salty or fresh? Moving or still? Big or small?
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: Land and water on Earth.
- 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.
