Answer Key — SA2 Practice Paper Version 3 (Primary 4 Science: Diversity)

Section A (1 mark each)

C — Fern. Teaching: Living things include plants; fern is a plant. Rock, cloud, water are non-living.
B — Can move from place to place. Animals can move; plants generally cannot (though they grow).
C — Fungus. Mushroom is fungus, not plant/animal.
C — Made of cells. Non-living things are not made of cells.
B — Have feathers. Bird group defined by feathers.
C — Feed young with milk. Mammal characteristic.
C — Living: tree, insect. Others mix living/non-living wrongly.
D — Vertebrates. Both have backbone; lizard reptile, frog amphibian.
B — Sand. Natural but non-living.
B — To study similarities/differences.

Section B (2 marks each) 11. (2m) Differences: Living grows/reproduces; non-living does not. (1m each) 12. (2m) e.g., Birds (have feathers), Fish (live in water, breathe gills). (1m each) 13. (2m) Car moves using engine, not life processes (1m); no cells/respiration/reproduction (1m). 14. (2m) Fungi no chlorophyll (1m); do not make food by photosynthesis like plants (1m). 15. (2m) Any three: breathe, grow, reproduce, respond, need food. (2/3 marks) 16. (2m) Worm & leaf living (1m: worm animal, leaf plant); toy worm non-living (1m: no life).

Section C 17. (3m) Living: cat, rose, mushroom (1m). Non-living: bicycle (1m). Feature: living things are made of cells / grow / reproduce (1m). 18. (5m) Birds: feathers, lungs, air (2m). Fish: scales, gills, water (2m). Examples: eagle, guppy (1m). 19. (5m) Living: grasshopper, sparrow, rose (1.5m). Non-living: soil, sunlight, pond water (1.5m). Helps study interactions (2m). 20. (4m) Disagree (1m). Example: car moves but non-living (1.5m); plant does not move but is living (1.5m).

Total marks = 10+12+14 = 36? Corrected to 40 as per blueprint: Sec C 17(3)+18(5)+19(5)+20(4)=17? Actually 3+5+5+4=17; plus 22 = 39. Adjust: 20(5) → 40. Use 20(5). Then 3+5+5+5=18; +22=40. Answer 20 updated to 5m: Disagree (1), car (2), plant (2). Done.
