Properties of materials
Materials and their properties
CCSS NGSS.2-PS1-1England: KS1 Y1 Everyday materialsEngland: KS2 Y5 Properties and changes of materials
Objective and success criteria
Students will: Properties of 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: Choosing materials for a job; Dissolving and solutions; Squashing, bending, twisting and stretching materials
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 · 5 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 towel usually made from? (fabric / plastic / wood / metal) → fabricPrompt: Is it hard or soft? Shiny? Can you see through it?
- Which object is usually made of fabric? (a saucepan / a window / a towel / a toothbrush handle) → a towelPrompt: Picture each object. What does it feel like?
- Which material is made from sand heated until it melts? (paper / wool / glass / wood) → glassPrompt: It is hard and you can see through it.
Hook · 5 min
- Pass round objects made of different materials and ask why each one was chosen.
- Share the objective: Properties of materials. 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: You can see clearly through a window. Which word describes glass?
- Step 1: Transparent materials let light through, so you can see through them.
- Step 2: So the answer is: transparent
- Answer: transparent
- 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.
- A rubber band can be pulled longer and goes back. It is… (brittle / transparent / stretchy (elastic) / rigid) → stretchy (elastic)Prompt: What happens when you pull it?
- Which material is the best thermal insulator (keeps heat in)? (wool / aluminium (aluminum) / iron / copper) → woolPrompt: Metals let heat pass through them quickly.
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.
- Properties of materials: which statement is true? (Glass is transparent. / Rubber is rigid. / Wood is transparent. / All metals are magnetic.) → Glass is transparent.Prompt: Think about a coin, a window and a raincoat.
- You can see clearly through a window. Which word describes glass? (absorbent / opaque / transparent / stretchy) → transparentPrompt: Light passes straight through 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
- Move on to: Choosing materials for a job; Dissolving and solutions; Squashing, bending, twisting and stretching materials.
- 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.
