Reduce, reuse or recycle?
Ecosystems and food chains
CCSS NGSS.K-ESS3-3England: EYFS Understanding the World: The natural worldEngland: KS1 Y2 Uses of everyday materials
Objective and success criteria
Students will: Reduce, reuse or recycle?.
- 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: no earlier skill in the map; start from what students know.
Leads to: Sort waste into the right recycling group; Actions that help or harm the environment
Materials: Food web cards, Arrows to build chains, Mini whiteboards, A diagram or short video clip of the idea, Printed student sheet (below).
Warm-up · 6 min
- Quick retrieval: three short questions students should already manage. Answers on mini whiteboards.
- Show answers together and note who needs support in the main task.
- Is this reducing, reusing or recycling: taking the same cloth bag to the shop each week? (reduce / reuse / recycle) → reusePrompt: Reduce = use less. Reuse = use again. Recycle = make into something new.
- Which of these is a way to recycle? (refilling a water bottle / printing on both sides of the paper / using a jam jar to store pencils / putting empty cans in the recycling bin) → putting empty cans in the recycling binPrompt: Is the item used less, used again, or turned into something new?
- Banana peel and apple cores can go in a compost bin. What happens to them? (They rot down into rich soil for plants. / They turn into plastic. / They stay the same for ever. / They turn into new bananas straight away.) → They rot down into rich soil for plants.Prompt: What do tiny living things like worms do to old food?
Hook · 6 min
- Show a food web and ask what would happen if one animal disappeared.
- Share the objective: Reduce, reuse or recycle?. 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: Is this reducing, reusing or recycling: using a jam jar to store pencils?
- Step 1: Reuse means using something again instead of throwing it away.
- Step 2: So the answer is: reuse
- Answer: reuse
- 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.
- Is this reducing, reusing or recycling: sending old newspapers to be made into new paper? (reduce / reuse / recycle) → recyclePrompt: Reduce = use less. Reuse = use again. Recycle = make into something new.
- Which of these is a way to reuse? (using a jam jar to store pencils / turning off the tap while you brush your teeth / printing on both sides of the paper / putting glass bottles in the bottle bank) → using a jam jar to store pencilsPrompt: Is the item used less, used again, or turned into something new?
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.
- Why is it good to recycle plastic bottles? (It makes the bottles heavier. / Less rubbish goes to landfill and the plastic can be made into new things. / It makes more plastic in the sea. / Recycled plastic turns into food.) → Less rubbish goes to landfill and the plastic can be made into new things.Prompt: Where does rubbish go if it is not recycled?
- Which of these is a way to reduce? (printing on both sides of the paper / putting glass bottles in the bottle bank / sending old newspapers to be made into new paper / refilling a water bottle) → printing on both sides of the paperPrompt: Is the item used less, used again, or turned into something new?
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
- Use concrete materials: food web cards.
- 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: Sort waste into the right recycling group; Actions that help or harm the environment.
- 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.
