Answers
Primary 4 Science Quiz - Materials (Answer Key)
Total Marks: 40
Section A: Multiple-Choice Questions (10 marks)
1. C [1]
Explanation: Matter is defined as anything that has mass and occupies space. While many forms of matter can be seen, some (like gases) are invisible. "Can be seen" is not a defining property of matter. All matter is made of particles.
2. B [1]
Explanation: Liquids have a definite volume but take the shape of their container (no definite shape). Solids have both definite shape and volume. Gases have neither definite shape nor volume.
3. D [1]
Explanation: The experiment demonstrates all three statements:
- Syringe A (solid) and B (liquid) cannot be compressed → solids and liquids have definite volume and cannot be compressed.
- Syringe C (gas) can be compressed → gases can be compressed.
Therefore, all statements are correct.
4. B [1]
Explanation: A cooking pot handle must not conduct heat well, otherwise it would burn the user's hand. Wood is a poor conductor of heat (insulator), while copper, aluminium, and steel are good conductors of heat.
5. C [1]
Explanation: Group X contains iron, steel, copper — all metals. Group Y contains plastic, wood, rubber — all non-metals. While metals are magnetic (iron/steel) and conduct heat, copper is non-magnetic. The most general classification is metals vs non-metals.
6. B [1]
Explanation: Heat travels from the hot tea through the metal spoon to the handle. Metals are good conductors of heat, allowing heat to transfer quickly through them.
7. C [1]
Explanation: In a gas, particles are far apart and move freely in all directions at high speeds. Option A describes solids, B describes liquids, D is incorrect for gases.
8. B [1]
Explanation: Inflating a balloon shows that air takes up space (occupies space) inside the balloon, causing it to expand. While air also has mass and can be compressed, the direct observation is that it occupies space.
9. B [1]
Explanation: Following the flowchart: No definite shape → No definite volume → Gas. But the question states "definite volume but no definite shape" → Yes to definite volume, No to definite shape → Liquid.
10. D [1]
Explanation: Copper and aluminium are good conductors of both electricity and heat. Glass is a poor conductor of both electricity and heat. There is no common material that conducts heat well but not electricity (at this level). The correct answer is "None of the above".
Section B: Structured Questions (10 marks)
11.
(a) Beaker C [1]
(b) Beaker C has the highest temperature (80°C). Heat flows from a hotter region to a cooler region. The greater the temperature difference between the hot water and the spoon handle, the faster the rate of heat conduction through the metal spoon. [1]
Marking note: Must mention temperature difference and heat flow direction.
12.
(a) Clear plastic sheet [1]
(b) It is transparent / allows light to pass through. [1]
Marking note: "Transparent" or "allows light to pass through" accepted. "See-through" accepted.
13.
(a) When heated, the metal ball expands (increases in size/volume). Its diameter becomes larger than the inner diameter of the ring, so it cannot pass through. [1]
Marking note: Must mention expansion/increase in size due to heating.
(b) Cool the metal ball (put it in cold water / leave it to cool to room temperature). [1]
Marking note: Cooling causes contraction, returning to original size.
14.
(a) Material W [1]
(b) A raincoat needs to be waterproof (to keep rain out), flexible (to wear comfortably), and strong (to last). Material W has all three properties. [1]
Marking note: Must link properties to function. Waterproof is essential; flexible and strong are supporting reasons.
15.
(a) Boiling [1]
(b) Condensation [1]
Marking note: "Evaporation" is incorrect for (a) as it occurs below boiling point. "Freezing" is liquid to solid.
Section C: Open-Ended Questions (20 marks)
16.
(a) 150 g [1]
(b) Mass is conserved during a change of state. The ice melts to become water, but no matter is lost (the containers have lids). The total mass of container + water remains the same. [1]
Marking note: Key concept: Conservation of mass during melting. Lids prevent evaporation loss.
(c) No, the observation is not correct. The mass is the same, but ice has a lower density than water, so 100 g of ice occupies a larger volume than 100 g of water. When ice melts, the volume decreases, so the water level should be lower, not higher. Wait — the question says "appears lower". Actually, the water level WILL be lower after melting because water is denser than ice. So the observation is CORRECT. Let me re-read: "The student observes that the water level in Container A appears lower than in Container B after the ice melts. Is this observation correct? Explain."
Yes, the observation is correct. Ice is less dense than water, so 100 g of ice occupies a larger volume than 100 g of water. When the ice melts, the volume decreases, resulting in a lower water level. [2]
Marking breakdown: 1 mark for "Yes/correct", 1 mark for explaining density difference (ice less dense than water → larger volume → level drops on melting). Common mistake: Thinking mass change causes level change.
17.
(a) To allow the metal sections to expand on hot days without buckling or bending. [1]
(b) The bridge would expand and have no room to expand into, causing it to buckle, bend, or crack, making it unsafe. [1]
(c) Any two of: Strong / high strength, durable / long-lasting, malleable (can be shaped), good conductor of heat (not directly relevant but acceptable), ductile. [2]
Marking note: 1 mark each. Best answers: Strong and durable. "Conducts heat" is less relevant for bridge structure.
18.
(a) Conductors: Copper coin, Aluminium foil [1]
Insulators: Plastic ruler, Wooden chopstick, Rubber band [1]
(b) Metals are ductile (can be drawn into wires) / malleable (can be hammered into shape) / strong / durable / good conductors of heat. [1]
(c) Plastic is an insulator of electricity / does not conduct electricity. Electrical wires need to conduct electricity, so plastic cannot be used for the conducting part of wires. [1]
Marking note: For (c), must state plastic does not conduct electricity.
19.
(a) Cup C (Styrofoam cup) [1]
(b) Styrofoam is a poor conductor of heat (good insulator). It slows down heat loss from the hot chocolate to the surroundings. [1]
(c) Metal is a good conductor of heat. It conducts heat away from the hot chocolate to your hand quickly, so it feels hotter. Styrofoam is a poor conductor of heat, so heat transfers slowly to your hand, making it feel less hot. [2]
Marking breakdown: 1 mark for identifying metal as good conductor / styrofoam as poor conductor. 1 mark for linking to rate of heat transfer to hand.
20.
(a) A: Evaporation [½] B: Condensation [½] C: Precipitation [½] D: Collection [½]
Total 2 marks. ½ mark each.
(b) Condensation (Process B) [1]
Explanation: Water vapour loses heat to the cooler surrounding air and changes into liquid water droplets (clouds).
(c) Any one of: Provides fresh water for drinking and irrigation / Replenishes water sources (rivers, lakes, groundwater) / Supports plant growth / Regulates Earth's temperature / Enables the survival of living things. [1]
Marking note: Accept any valid importance of water cycle.
