Answers
Primary 3 Science Quiz - Systems: Answer Key
Topic: Systems
Version: 1 of 5
Total Marks: 40
Section A: Multiple Choice (1 mark each)
1. B Rose plant
Teaching note: Living things include plants. A rose plant needs water, air, and food, and can grow and reproduce. Toy car, chair, and cup are non-living made by humans.
2. B animals
Teaching note: Both birds and fish are animals. They are living things that move and breathe; plants and fungi are different groups.
3. B Plastic
Teaching note: Plastic is waterproof (does not absorb water), so it keeps the body dry. Paper and tissue absorb water; cotton is not fully waterproof.
4. C Made of metal
Teaching note: Living things are not defined by being metal. They need food, can grow, and reproduce.
5. C fungi
Teaching note: Mushrooms are fungi, not plants (they do not make food from sunlight) and not animals.
6. B North–South
Teaching note: A freely suspended bar magnet aligns with Earth’s magnetic field, pointing North–South.
7. B North and North
Teaching note: Like poles repel. Unlike poles (N–S) attract. Iron is attracted but not a pole; wood is non-magnetic.
8. B flexible and waterproof
Teaching note: Rubber bends without breaking (flexible) and does not let water through (waterproof).
9. A egg
Teaching note: Butterfly life cycle: egg → caterpillar → pupa → adult butterfly.
10. C Fish
Teaching note: Fish use gills to breathe underwater. Cats use lungs; adult frogs use lungs/skin; butterflies breathe through holes.
