Student lesson
- Properties describe materials.
- Tests give evidence.
- Properties decide uses.
- Different jobs need different materials.
Words to know
a feature that describes how a material behaves
able to bend without breaking
able to soak up liquid
able to last a long time
1. Discover: The raincoat
Naa needs a coat for the rainy season. She tests three fabrics with water drops: cotton soaks up the water, nylon lets it run off, and wool soaks it slowly. “Nylon is waterproof,” she writes. “It is the best choice for a raincoat.”
Think: Which property did Naa test?
2. Understand: Properties
Idea 1: Describing materials
A property tells how a material behaves: hard or soft, flexible or stiff, rough or smooth, absorbent or waterproof, shiny or dull.
Idea 2: Testing
We test properties with fair tests: scratch for hardness, bend for flexibility, drip water for absorbency. Record results in a table.
Idea 3: Choosing
We match properties to jobs. A raincoat needs waterproof and flexible material; a pan needs a material that conducts heat; a hammer needs to be hard and durable.
3. Worked examples
Example 1 (I show you): Test
Cotton vs nylon.
- Water drops.
- Cotton soaks.
- Nylon repels.
Answer: Nylon is waterproof.
Example 2 (We do it together): Choose
Window.
- Transparent.
- Hard.
- Glass.
Answer: Glass suits windows.
Example 3 (You try): Choose
Mop.
Show the steps and answer
- Absorbent.
- Flexible.
- Cotton.
Answer: Cotton suits a mop.
Did you know?
Spider silk is five times stronger than steel of the same thickness yet is also flexible.
Why this matters
Choosing the right material makes things last and work well.
4. Explore: Material tests
Test six materials for three properties and record.
- Choose six materials.
- Test absorbency with drops.
- Test flexibility by bending.
- Record in a table.
Think about it: what did you notice?
What did you notice? No single material was best for every job.

Mastery and remediation
| Objective | Bronze (Developing) | Silver (Proficient) | Gold (Advanced) |
|---|---|---|---|
| O1 Name material properties | Shows this with help from an adult or a picture | Does this independently and explains how they know | Explains it clearly and uses it in a new situation |
| O2 Test properties fairly | Shows this with help from an adult or a picture | Does this independently and explains how they know | Explains it clearly and uses it in a new situation |
| O3 Compare materials in a table | Shows this with help from an adult or a picture | Does this independently and explains how they know | Explains it clearly and uses it in a new situation |
| O4 Match properties to uses | Shows this with help from an adult or a picture | Does this independently and explains how they know | Explains it clearly and uses it in a new situation |
Courseversity badge thresholds (overall quiz score): Gold = 90–100%; Silver = 80–89.9%; Bronze = 70–79.9%. A badge is never a full record of progress.
If a learner struggles
- Find the misconception: “The strongest material is always best.” Depends on the job.
- Explain another way: use real objects, pictures or actions first, then words.
- Show a simpler example: Test and choose materials.
- Guided practice: work through one example together and let the learner try the next one.
- Reassess: use the quiz again or the worksheet.
- Move on when the learner shows Silver-level evidence independently.
For parents and guardians
In this lesson your child tests material properties. You do not need to be an expert to help.
- Test home materials.
- Ask “Why this material?”
- Use safe items.
- Ask “how do you know?” after each answer, and listen.
- Praise effort, not only right answers. Mistakes are how we learn.
- Ten to fifteen minutes a day is better than one long session.
Teacher package
1–5. Objectives, prerequisites, materials, preparation, duration
Lesson objectives. Learners will: name material properties; test properties fairly; compare materials in a table; match properties to uses.
Prerequisite knowledge. Grade 3 matter ideas: solids, liquids, gases, heating and cooling, melting, freezing and evaporation.
Materials. Fabrics, dropper. Low-resource options: use chalk or charcoal on a board or wall, drawings in the sand, and objects from the classroom instead of printed materials.
Preparation. Cut samples.
Suggested duration. 45–60 minutes. It can be split into two shorter sessions.
6–9. Teaching procedure, explanation notes, guided and independent activities
Introduction (5 min). Show a raincoat and ask, “Why is it made of this?”
Explanation (10 min). Teach properties.
Guided activity (10 min). Learners test.
Independent activity (10 min). Learners choose.
Assessment and reflection (5 min). Ask each learner to say one thing they learned and how they know it.
Key questions. Which property? Which job?
Teacher explanation notes. Start with real objects and safe, hands-on observation. Then talk about what was seen, then draw and write. Always say “how do you know?”. Keep to the safety notes, and use local, safe materials.
10–12. Differentiation, formative assessment, common misconceptions
Support. Use real objects and pictures, short sentences and a partner. Let learners point, show or draw instead of writing. Extension. Ask learners to find a new example at home and explain how they know.
Formative assessment. Listen to learners read and explain, ask “how do you know?”, and check the independent work.
Misconceptions. “The strongest material is always best.” Depends on the job.
13–15. Assessment questions, answer keys, marking scheme
Use the quiz, the 10-mark exam practice and the worksheet on this page. All answers and marking guides are in the answer sections above. Re-check every answer before use.
16–19. Remediation, enrichment, homework, teacher reflection
Remediation. Test and choose materials. Enrichment. Look for one new example near your home or school, draw it and explain it to someone. Homework. See above.
Teacher reflection. After teaching, record: which ideas learners understood; which misconceptions occurred; which activities worked; which learners need more practice; and what to improve next time.
