Primary 5 Science Quiz - Materials: Answer Key

Total Marks: 40
Topic: Materials

Section A: Multiple Choice (1 mark each)

B – A solid has a fixed shape and fixed volume because its particles are tightly packed in place.
Teaching note: Liquids have fixed volume but take container shape; gases have neither fixed.
B – Conductor. Materials that allow electricity to flow easily are conductors (e.g., metals).
Common mistake: Choosing non-metal; some non-metals are insulators.
C – Rubber band is an insulator. Copper, iron, aluminium are conductors.
Marking: 1 mark for C.
B – Evaporation is liquid → gas at surface below boiling point.
Note: Boiling happens throughout liquid at 100 °C.
A – Melting point of ice = 0 °C (from syllabus).
Common mistake: 10 °C is a typo seen in drafts; official is 0 °C.
B – Condensation: gas → liquid when cooled.
Teaching: Water vapour loses heat, becomes droplets.
B – Plastic is an insulator, does not conduct heat well; safe handle.
Note: Metal handles conduct heat and burn hands.
C – Closed circuit = complete path for current.
Marking: Open switch or broken wire = no current.
B – Cotton is natural (from plants). Others are human-made.
Teaching: Natural materials come from nature; synthetic from chemicals.
C – Boiling point of water = 100 °C.
Syllabus value confirmed.

Section B: Short Answer (2 marks each)

Liquid: fixed volume, takes shape of container. Gas: no fixed shape, no fixed volume. [1+1]
Accept any correct property pair.
Wood is an insulator / poor conductor of heat, so it does not get too hot; metal conducts heat and burns hand. [1 for insulator property, 1 for safety reason]
Conductors: copper, aluminium (or iron, silver). Insulators: rubber, plastic (or wood, glass). [1+1]
Particles gain heat energy, vibrate more, break fixed positions, become able to move past each other (liquid). [2 for describing particle change]
Two from: open switch, broken wire, no battery, dead bulb, wrong connection. [1 each]
Boiling point of water = 100 °C, melting point of ice = 0 °C. [1+1]

Section C: Structured (8 marks)

(a) Glass – insulator; Silver – conductor; Wood – insulator; Copper – conductor. [0.5 each = 2]
(b) Insulators stop electricity from flowing where not wanted, preventing shock/fire. [1]
(a) Evaporation is the change of liquid to gas at the surface below boiling. [1]
(b) Higher temperature, larger exposed surface area, wind / air movement. [1+1, any two]
(a) Drawing shows battery, bulb, switch, wires in closed loop. [1]
(b) Electric current (or electricity) flows. [1]
(a) Solid, liquid, gas. [1, 0.33 each if split]
(b) Evaporation. Sun heats water, water particles gain energy and escape as vapour, amount decreases. [1 process + 1 explanation]
