Primary 5 Science Quiz - Materials

Answer Key

Section A: Multiple Choice Questions

1. C (Cotton)

Cotton is a natural material obtained from the cotton plant. Plastic, nylon, and polyester are synthetic (man-made) materials.
[1 mark] Award 1 mark for the correct answer.

2. C (Elasticity)

Elasticity is the property of a material that allows it to be stretched and return to its original shape. Flexibility refers to the ability to bend without breaking, but does not necessarily imply returning to the original shape.
[1 mark] Award 1 mark for the correct answer.

3. C (Copper)

Copper is a metal and an excellent conductor of heat. Wood, rubber, and glass are poor conductors of heat (insulators).
[1 mark] Award 1 mark for the correct answer.

4. B (Insulator)

An insulator is a material that does not allow electricity to pass through it easily. A conductor allows electricity to flow through it.
[1 mark] Award 1 mark for the correct answer.

5. D (Plastic)

Plastic is waterproof and does not absorb water. Paper, cotton cloth, and silk absorb water.
[1 mark] Award 1 mark for the correct answer.

6. B (Ceramic)

Glass is classified as a ceramic material. It is made by heating sand (silica) to a very high temperature.
[1 mark] Award 1 mark for the correct answer.

7. B (Good heat conduction)

Cooking pots need to conduct heat well so that food can be heated evenly and efficiently.
[1 mark] Award 1 mark for the correct answer.

8. C (Steel)

Steel is an alloy (mixture of iron and carbon) and is man-made. Wood, leather, and wool are natural materials.
[1 mark] Award 1 mark for the correct answer.

9. C (Transparent)

A transparent material allows all light to pass through it. An opaque material blocks all light. A translucent material allows some light through.
[1 mark] Award 1 mark for the correct answer.

10. C (Rubber)

Rubber is an electrical insulator and is flexible, making it suitable for covering electrical wires to prevent electric shocks. Aluminium, silver, and iron are conductors.
[1 mark] Award 1 mark for the correct answer.

Section B: Short Answer Questions

11. [2 marks]

(a) Copper is a good conductor of electricity. [1]
(b) Copper is flexible (can be drawn into wires). [1]
Acceptable alternatives for (b): Copper is abundant / ductile / does not corrode easily.
[Marking note: Award 1 mark for each correct property. Do not accept vague answers like "cheap" without further justification.]

12. [4 marks]

Material	Natural or Synthetic?
Rubber (from rubber tree)	Natural
Nylon	Synthetic
Bamboo	Natural
Polyester	Synthetic

[Marking note: Award 1 mark for each correct classification.]

13. [2 marks]

Wood is a poor conductor of heat (thermal insulator). [1]
This prevents heat from the hot utensil from reaching the user's hand, so the user does not get burned. [1]
[Marking note: The answer must mention both the property (poor heat conductor / insulator) and the reason (prevents burns / protects hand). Award 1 mark for each point.]

14. [4 marks]

(a) Q is the most flexible. [1]
(b) S is the least flexible. [1]
(c) S < P < R < Q [2]
[Marking note: Award 2 marks for the full correct order. Award 1 mark if 2 out of 3 comparisons are correct. Award 0 marks if more than one comparison is wrong.]

15. [2 marks]

Advantage: Plastic bags are lightweight / waterproof / cheap / strong for their weight / easy to carry. [1]
Disadvantage: Plastic bags are not biodegradable / cause pollution / harm wildlife / contribute to landfill waste. [1]
[Marking note: Accept any valid advantage and disadvantage. Award 1 mark each.]

16. [3 marks]

(a) Suggested material: Metal (e.g., aluminium or steel) / corrugated zinc sheets / clay tiles / polycarbonate sheets. [1]
(b) Explanation: The material is waterproof so rain does not enter the house. It is strong enough to withstand wind and weather. It is lightweight so it does not put too much stress on the walls of the house. [2]
[Marking note: Award 1 mark for a suitable material. Award up to 2 marks for the explanation — at least two relevant properties must be linked to the material's suitability.]

Section C: Structured / Application Questions

17. [4 marks]

(a) Plastic would be the best choice for the handle of a kettle. [1] Plastic does not conduct heat, so it will not get hot when the kettle is heated, and the user will not get burned when holding the handle. [1]
(b) Plastic would be the best choice for making a raincoat. [1] Plastic is waterproof, so it will prevent rain from reaching the person wearing it. It is also flexible, making it comfortable to wear. [1]
[Marking note: Award 1 mark for identifying the correct material and 1 mark for a valid explanation in each part.]

18. [4 marks]

(a) Two things to keep the same (fair test):
- (i) The length and thickness/diameter of both rods. [1]
- (ii) The size/mass of the wax blobs attached to each rod / the heat of the flame applied / the distance from the flame to the wax blob. [1]
- Acceptable alternatives: Same type of wax, same time of heating, same starting temperature.
(b) The wax blob on the metal rod would melt first / fall off first. [1] This is because metal is a good conductor of heat, so heat travels quickly along the metal rod to melt the wax. [1]
[Marking note: Award 1 mark for each correct fair test variable. Award 1 mark for the correct prediction and 1 mark for the correct explanation.]

19. [3 marks]

Plastic is the best material for Sarah's water bottle. [1]
Glass is waterproof and can be lightweight, but it is breakable / fragile, so it does not meet the "unbreakable" requirement. [1]
Aluminium is strong and unbreakable, but it is heavier than plastic and can react with certain liquids / may not be as lightweight. [1]
Plastic is lightweight, unbreakable, and waterproof, meeting all three of Sarah's requirements.
[Marking note: Award 1 mark for recommending plastic. Award up to 2 marks for valid comparisons with the other two materials. Accept any well-reasoned answer that addresses the three criteria.]

20. [2 marks]

The statement is false. [1]
Not all metals are magnetic. Only certain metals such as iron, nickel, and cobalt are magnetic. Metals like aluminium, copper, gold, and silver are not magnetic. [1]
[Marking note: Award 1 mark for identifying the statement as false. Award 1 mark for a correct explanation with at least one example of a non-magnetic metal.]
