Answers

Primary 6 PSLE Science Quiz - Materials: Answer Key

Total Marks: 40
Topic: Materials (syllabus-first, LLM-inferred; not past-year derived)

Section A Answers (1 mark each)

C – A good conductor of heat allows heat to pass through easily. (Teaching note: Metals are common heat conductors; choice A describes a feeling not a property, B is insulator, D is not always true.)
B – Flexible means it can bend without breaking. (Brittle breaks, transparent see-through, magnetic pulled by magnet.)
B – Iron rusts in the presence of air and water. Plastic, glass, rubber do not rust.
B – Transparent materials let light pass so we can see through. Opaque blocks light.
B – Porous materials have tiny holes that absorb liquid. Sponge is porous.
B – Cotton is natural (from plants). Nylon, polythene, acrylic are man-made.
B – Steel is strong and used for cables/bridges. Wood/paper/foam not strong enough.
C – Reusing means using again for same/new purpose; old jar for snacks is reuse. D is recycle, A/B are disposal.
C – Rubber is flexible and gives grip; not good heat conductor, not transparent, does not rust.
A – Recycling processes used paper into new paper. Burning/composting/evaporation not paper-making.

Section B Answers (2 marks each)

Properties: (any two) waterproof, light, does not break easily, can be moulded into shape. [2 marks – 1 per correct property]
Teaching: Plastic is versatile; food containers need to keep food dry and be safe.
Answer: Wood is a poor conductor of heat, so it does not get as hot as metal; safer to hold. [2 marks – 1 for poor conductor, 1 for safety]
Common mistake: saying wood is "cold" not "does not conduct heat".
Answers: (any two) use reusable bags, recycle paper, compost food, avoid single-use items. [2 marks – 1 each]
Cotton: absorbs water / soft / breathable. Rubber: waterproof / flexible. [2 marks – 1 each]
Teaching: Cotton suits shirt as comfortable; rubber suits raincoat as keeps rain out.
Iron and steel (or nickel, cobalt). [2 marks – 1 each]
Note: Only magnetic materials attracted to magnet.
Answer: Recycling saves resources and energy, reduces landfill and pollution. [2 marks – 1 save resources, 1 reduce harm]
Teaching: Aluminium from ore needs much energy; recycling reuses metal.

Section C Answers (8 marks total)

(a) A material is something used to make objects. [1]
(b) Man-made: plastic / nylon. Natural: wood / cotton. [1]
Teaching: Materials are classified by origin.
(a) Property: transparent / hard / waterproof. [1]
(b) Use: window / bottle / lens. [1]
Marking: Must link use to stated property.
(a) Does not let water pass through. [1]
(b) Waterproof: rubber / plastic. Not: paper / cotton. [1]
(a) Saves resources / reduces pollution / protects environment. [1]
(b) Use both sides of paper / recycle / reuse items. [1]
