Primary 4 Science Quiz - Materials (Answer Key)

Total Marks: 30
Section A: 8 marks (Q1–8, 1 mark each)
Section B: 12 marks (Q9–14, 2 marks each)
Section C: 18 marks (Q15–20, 3 marks each)

Section A Answers

1. B (Brittle) [1]
Teaching note: Brittle means a material breaks easily when force is applied (like glass or dry clay). Hardness is resistance to scratching; flexible means can bend; absorbent means soaks water.

2. Permeable [1]
Teaching note: A permeable material has tiny holes or spaces that let water pass through (e.g., cloth, sponge). The opposite is waterproof/impermeable.

3. C (Metal) [1]
Teaching note: Metals such as iron, aluminium, and steel are good conductors of heat. Wood, plastic, rubber are poor conductors (insulators).

4. Flexible / absorbs shock / grippy [1]
Teaching note: Rubber is flexible and has good grip, so it stops feet from slipping and bends with movement.

5. C (Plastic sheet) [1]
Teaching note: Plastic sheet does not let water through. Cotton, paper, sponge all absorb or leak water.

6. Flexible [1]
Teaching note: Flexible means can be bent or shaped without breaking (e.g., rubber, cloth).

7. Transparent / clear (lets light through) [1]
Teaching note: Glass is transparent so we can see outside while being protected from weather. (Note: P4 syllabus does not require "transparent/translucent/opaque" terms, but "clear" or "lets light through" is acceptable.)

8. C (Nylon) [1]
Teaching note: Nylon is man-made (synthetic). Wood, cotton, rubber come from nature (plants/trees).

Section B Answers

9. [2]
Answer: Plastic bottle is better. (1) Plastic is waterproof so water will not leak. (1) Paper cup is absorbent and will become wet and break.
Teaching note: Property–use match: waterproof → holds liquid.

10. [2]
Answer: Metal spoon feels hotter. (1) Metal is a good conductor of heat, so heat from soup moves into spoon quickly. (1) Wood is poor conductor so stays cooler.
Teaching note: Conductor = material that lets heat flow easily.

11. [2]
Answer: Rubber – use: shoe soles / tyres (1). Glass – property: transparent / hard / waterproof (1).
Teaching note: Table tests linking property to everyday use.

12. [2]
Answer: Sponge has many small holes/spaces. (1) It soaks up and holds water inside those spaces. (1)
Teaching note: Absorbent = takes in liquid.

13. [2]
Answer: Mei Lin stayed dry. (1) Plastic is waterproof; cotton is absorbent and soaks rain. (1)
Teaching note: Raincoat must block water.

14. [2]
Answer: Any two: strong, good conductor of heat, does not break easily, can be shaped. (1+1)
Teaching note: Pot needs to transfer heat and be durable.

Section C Answers

15. [3]
(a) Cloth bag (strongest) – 1
(b) Plastic bag (waterproof) – 1
(c) Plastic does not let water pass through; cloth and paper absorb water – 1
Teaching note: Property determines function.

16. [3]
(a) Metal rod – 1
(b) Metal is a good heat conductor, so heat from water moves into it – 1
(c) Wooden stick (or plastic ruler) feels coolest as poor conductor – 1
Teaching note: Heat flows from hot to cold; conductor speeds this.

17. [3]
(a) Cotton towel: absorbent, used to dry body – 1
(b) Rubber ball: flexible/bouncy, used for play – 1
(c) Glass cup: transparent/hard, used to hold drinks – 1
Teaching note: Image shows labelled objects; pupil links material to property and use.

18. [3]
(a) Metal > plastic > wood (best to worst) – 1
(b) Touch each after 5 min and rate warmth, or use thermometer on each – 1
(c) Same water amount keeps test fair (only material changes) – 1
Teaching note: Fair test needs controlled variables.

19. [3]
(a) Plastic – 1
(b) Waterproof and strong (or light) – 2 (1 each)
(c) Paper absorbs water and tears when wet – 1 (can be merged with b reason)
Teaching note: Umbrella must block rain and last.

20. [3]
Answer: Properties help us pick right material. Example 1: Metal pot – good heat conductor for cooking. Example 2: Rubber soles – flexible/grippy for shoes. (1 for idea, 2 for examples)
Teaching note: Always match property to need.

Common mistakes to flag:

Confusing "heat" and "temperature": heat is energy, temperature is how hot.
Saying all plastics are flexible (some are hard).
Using P5/P6 terms like "xylem" or "transparent" strictly (use "lets light through").
