Objective and success criteria
Students will: Natural or human-made materials?.
- 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: Everyday materials
Leads to: the next skill in this area.
Materials: A tray of everyday objects, Sorting hoops, Mini whiteboards, A diagram or short video clip of the idea, Printed student sheet (below).
Warm-up · 6 min
- Quick retrieval from earlier learning (Everyday materials). Students answer on mini whiteboards.
- Show answers together and note who needs support in the main task.
- What is a jam jar usually made from? (fabric / glass / metal / plastic) → glassPrompt: Is it hard or soft? Shiny? Can you see through it?
- Which object is usually made of wood? (a seaside bucket / a mirror / a curtain / a garden shed) → a garden shedPrompt: Picture each object. What does it feel like?
- Which of these is a material, not an object? (table / wood / chair / door) → woodPrompt: A material is what something is made of.
Hook · 6 min
- Pass round objects made of different materials and ask why each one was chosen.
- Share the objective: Natural or human-made materials?. 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 material natural or human-made: concrete?
- Step 1: Human-made materials are made by people changing other materials, often with heat.
- Step 2: So the answer is: human-made
- Answer: human-made
- 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 material natural or human-made: wood? (natural / human-made) → naturalPrompt: Could you find it like that in nature, or does a factory have to make it?
- Where does this material come from: plastic? (clay baked in a kiln / sand heated until it melts / the fluffy seed pods of a cotton plant / oil from under the ground) → oil from under the groundPrompt: Every human-made material starts as something natural.
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.
- Where does this material come from: a woolly jumper (sweater)? (the fluffy seed pods of a cotton plant / a sheep's fleece / sand heated until it melts / oil from under the ground) → a sheep's fleecePrompt: Every human-made material starts as something natural.
- Is this material natural or human-made: wood? (natural / human-made) → naturalPrompt: Could you find it like that in nature, or does a factory have to make it?
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: Everyday materials.
- Use concrete materials: a tray of everyday objects.
- 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.
