TuitionGoWhere Practice Paper - Science Primary 4 — Answer Key

Subject: Science | Level: Primary 4 | Topic: Diversity (Version 1 of 5) | Total Marks: 45

Section A: Multiple Choice (1 mark each)

B — All mammals have hair on their bodies.
B — Moss is a living thing; it grows and responds to surroundings.
C — Feathers, wings and hard-shelled eggs show it is a bird.
C — Plastic sheet is waterproof.
B — Mushrooms are fungi; they lack leaves, stems and roots and cannot make their own food.
D — Hair covering leads to "Mammal" in the key.
C — Ferns are plants that make their own food.
D — Living things grow and change size; staying the same size is not a life process.
B — Glass lets light through, so windows can be seen through.
B — This is classification.

Section B: Short Answer (3 marks each)

11. Any three: they grow; they reproduce; they respond to changes; they need air, water and food; they die/limited lifespan. (1 mark each)

12. Fish live in water while birds mostly live on land/fly; fish have scales and fins/gills while birds have feathers and beaks/wings. (Any two clear differences; 1½ marks each, awarded in halves rounded per school practice.)

13. Glass is transparent (allows light through); it is waterproof/hard and keeps rain and wind out. (Any two reasons, 1 mark each; 1 mark for clarity.)

14. Group 1 (Metals): iron nail, steel spoon. Group 2 (Non-metals): plastic bottle, wooden ruler. (1 mark per correct grouping + 1 mark for naming both groups.)

15. Similarity: both are living things/fungi and plants grow and reproduce. Difference: plants make their own food (have chlorophyll/leaves) while fungi cannot and feed on dead or decaying matter.

Section C: Open-Ended (4 marks each)

16. (a) Plants: moss (A), fern (C), hibiscus (D). Fungi: mushroom (B). (½ mark each) (b) Mushroom has no leaves, stems or roots and cannot make its own food, so it is a fungus. (2)

17. Choose plastic. Plastic is waterproof so rain will not soak through, while paper absorbs water and tears when wet. Plastic is also stronger and more durable against wind. (Choice: 1; comparison with reasons: 3.)

18. W: fish; X: mammal; Y: bird; Z: insect. (1 mark each)

19. Benefit 1: Books are easier to find because similar books are kept together. Benefit 2: Easier to return/shelve books and notice missing ones; saves time. (2 marks per benefit with explanation.)

20. Any three, with reasons: clean water (fish live and breathe in water); oxygen/aerator (fish breathe dissolved oxygen through gills); fish food (for energy to grow and stay alive); suitable temperature/clean bowl (to stay healthy). (1 mark per point with reason, max 4.)
