Objective and success criteria
Students will: Energy stores and transfers.
- 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: Sunlight warms things
Leads to: How devices transfer energy; Renewable and non-renewable energy resources; Energy in food
Materials: Wind-up toys or a pendulum, Energy transfer diagrams, Mini whiteboards, A diagram or short video clip of the idea, Printed student sheet (below).
Warm-up · 5 min
- Quick retrieval from earlier learning (Sunlight warms things). Students answer on mini whiteboards.
- Show answers together and note who needs support in the main task.
- How can you keep a playground cooler on a sunny day? (take away all the trees / add more metal / paint it black / put up a shade (canopy) or plant trees) → put up a shade (canopy) or plant treesPrompt: What blocks sunlight?
- Sunlight: which statement is true? (Sunlight gives us light and warmth. / White clothes get hotter in the sun than black clothes. / The Sun only warms things in summer. / Shade is warmer than sunshine.) → Sunlight gives us light and warmth.Prompt: Think about standing in the sun and in the shade.
- Sunlight: which statement is NOT true? (It is usually cooler in the shade than in sunshine. / The Sun gives us light but no warmth. / Dark colours warm up faster in sunlight than light colours. / The Sun warms the land, air and water.) → The Sun gives us light but no warmth.Prompt: Which colour reflects sunlight?
Hook · 5 min
- Wind up a toy or stretch an elastic band and ask where the energy goes.
- Share the objective: Energy stores and transfers. Read the success criteria together.
I do: model it · 10 min
- Work through the example out loud, saying why you do each step, not just what you do.
- Example: Which energy store is most important here: a drawn bow?
- Step 1: Stretched or squashed objects have an elastic potential energy store.
- Step 2: So the answer is: elastic potential (stretch or squash)
- Answer: elastic potential (stretch or squash)
- Pause after each step and ask a student to say what comes next.
We do: guided practice · 10 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 energy store is most important here: petrol (gasoline)? (elastic potential (stretch or squash) / gravitational potential (height) / chemical / thermal (heat)) → chemicalPrompt: Is it moving, raised up, stretched, hot, or able to release energy by reacting?
- A ball is dropped. Which energy store decreases as it falls? (gravitational potential / kinetic / nuclear / elastic) → gravitational potentialPrompt: It is getting lower.
You do: independent practice · 10 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 · 5 min
- Two questions on their own. Sort answers into got it / nearly / not yet to plan the next lesson.
- Which of these mainly has a chemical energy store? (a stretched trampoline / a stretched rubber band / a piece of coal / a book on a high shelf) → a piece of coalPrompt: Think about what each object is doing.
- Which are ways energy can be transferred? (by heating, by electric current, by light and sound, by forces / only by wires / energy cannot move / only by fire) → by heating, by electric current, by light and sound, by forcesPrompt: Think of a lamp, a speaker and a kettle.
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: Sunlight warms things.
- Use concrete materials: wind-up toys or a pendulum.
- Give the first step of each question, or a partly worked example to finish.
- Pair with a confident partner for the guided practice.
Stretch
- Move on to: How devices transfer energy; Renewable and non-renewable energy resources; Energy in food.
- 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.
