TuitionGoWhere Practice Paper - Science Primary 4 — Answer Key

Subject: Science | Level: Primary 4 | Topic Focus: Diversity (Version 3 of 5) | Total Marks: 50

AI-generated marking scheme. Accept other reasonable answers that show correct understanding.

Section A: Multiple Choice (5 marks)

B — moss, mould and mushroom are all living things (fungi/plants).
C — a cloud has never been alive; it does not grow, feed or reproduce.
A — growing, needing food and responding are characteristics of living things.
B — glass is transparent, so it lets light pass through for seeing out.
B — an umbrella must be waterproof to keep the user dry.

Section B: Short Answer (18 marks)

Any three: air, water, food. (Also accept: warmth/a suitable place to live.) (2 m)
Living: ant, fern, mushroom. Non-living: stone, plastic bottle, rain. (2 m — ½ mark per item up to 2)
A living thing can grow, respond to changes, reproduce and eventually die; a thing that has never been alive cannot do these things. (Any one clear difference; 2 m)
Any two: mould grows; it reproduces (produces spores); it feeds on other things (e.g., bread); it respires/needs air and moisture; it dies. Movement is not needed to be alive. (2 m)
(a) True (b) False — metals are usually opaque/shiny, not see-through. (2 m — 1 each)
Wood. Wood floats in water (it is less dense than water), while metal sinks, so a wooden boat will float. (2 m)
(a) Towel: cotton/fabric (absorbs water). (b) Window pane: glass (transparent). (2 m — 1 each)
Any one: plastic is lighter than glass; it does not break/shatter as easily as glass, so it is safer. (2 m)
Made from things that were once alive: paper (from trees), cotton shirt (from cotton plant), leather shoes (from animal skin). Not made from things that were once alive: glass marble. (2 m)

Section C: Structured Questions (12 marks)

Scales: guppy, snake. Feathers: sparrow. Fur: cat. (4 m — 1 per animal correctly placed)
(a) Bag B (woven plastic bag). (1 m) (b) Any two: plastic is stronger and does not tear easily under heavy weight; it is waterproof, so wet or damp cans will not weaken it; paper tears easily when wet or heavy. (2 m) (c) Any one: comfortable/foldable, reusable, light. (1 m)
Examples (accept others): Plants — hibiscus/fern/grass. Animals — cat/guppy/bird. Fungi — mushroom/mould/yeast. Microorganisms — bacteria (e.g., those in yoghurt). (4 m — 1 each)

Section D: Open-Ended Questions (15 marks)

(a) Non-living. (1 m) (b) Any two observations linked to life processes: it does not grow (living things grow); it does not need food (living things need food); it does not respond to changes/touch (living things respond). (2 m) (c) Any one: dead fallen leaf, wooden chair/table, paper, cotton T-shirt, leather belt. (2 m — 1 for valid example, 1 for brief reason that it came from a living thing but is not alive now)
(a) Material Y (plastic sheet). (1 m) (b) Any two: Y did not absorb water while X and Z did; Z tore when wet, so it would not last; X soaks water so the wearer would get wet. (2 m) (c) Any one: flexible (can bend with the body), light, strong/does not tear easily, comfortable to wear. (2 m)
Model answer (accept any correct grouping with a stated rule):

Group 1 (flexible)	Group 2 (stiff/rigid)
rubber band, sponge, balloon, eraser	iron nail, glass lens, steel spoon, mirror

Grouping rule: whether the objects are flexible (can bend/change shape easily) or stiff/rigid. (5 m — 2 m for all eight items correctly placed, 2 m for a clear, correct grouping rule, 1 m for presentation/table completed)

Alternative accepted grouping: metal objects (iron nail, steel spoon) vs non-metal objects (rubber band, glass lens, sponge, balloon, mirror, eraser).
