ANSWER KEY and MARKING GUIDELINES

SECTION A (15)
1 D, 2 B, 3 B, 4 C, 5 B, 6 A, 7 B, 8 C, 9 B, 10 B, 11 B, 12 A, 13 C, 14 B, 15 D
(Each 1 mark)

SECTION B (25)
1. Solution: a mixture where a substance (solute) dissolves in a liquid (solvent) so it looks the same throughout. (2)
2. Examples: rocks, water, soil, air, fallen logs (any two). (2; 1 each)
3. Effects of friction: slows things down, causes heat, wears surfaces away. (2; 1 each)
4. Separate rice and sand: use a sieve/screen, blow away lighter rice/husk (or hand picking), add water to float rice? Best: sieving/screening and using water if densities differ. (2)
5. Ends: north and south poles. (1)
6. Series circuit drawing: battery (cells) → wires → bulb → switch in series; labels (4)
Mark: correct symbols and labels (4); minor drawing errors deduct accordingly.
7. Conductor: copper/iron/steel; Insulator: plastic/rubber/wood/glass. (2)
8. Main source of energy for most food chains: the Sun. (1)
9. Difference: plants make their own food (photosynthesis) and have chlorophyll/green leaves; animals do not make food and move (or plants have roots, etc.). (2)
10. Safety: Do not touch wires with wet hands; switch off before connecting; use low voltage batteries only, etc. (1)
11. Liquid to gas: evaporation. (1)
12. Push example: pushing a swing, pulling example: opening a drawer (3; 1.5 each)

SECTION C (40)
1. Life cycles (10)
a. Frog life cycle: egg → tadpole (larva) → tadpole with legs/juvenile → adult frog. (4 marks: 1 per correctly named/drawn stage and arrows)
b. Tadpoles live in water and breathe with gills; adult frogs breathe air and may live on land and water, different food needs. (2)
c. Help: protect wetlands, avoid pollution, plant native plants, prevent draining of ponds. (2; 1 each)
d. If frogs die out, insect population (e.g., mosquitoes) may increase, affecting balance and possibly spreading disease; predators that eat frogs lose food. (2)

2. Materials (10)
a. Wooden spoon: not flexible (stiff), not a good conductor of heat (or poor conductor compared to metal) — note: wood is poor conductor so it stays cooler.
Metal spoon: not flexible (usually stiff) or slightly flexible depending; good conductor of heat.
Plastic spoon: flexible (often), poor conductor of heat. (4; 1.25 per item for two properties)
b. Cooking pots chosen because: good conductors of heat (even heating), strong and hard-wearing, safe at high temperatures, does not react with food (two reasons = 2 marks)
c. Experiment oil + water:
- Put water in a clear glass, add oil on top, stir gently.
- Observe that oil floats and forms a separate layer; droplets of oil will not mix; you may add food colouring to water to show separation.
- Explain: oil is less dense and immiscible with water; they form two layers. (4 marks: 2 for steps, 2 for expected observation/explanation)

3. Electricity (10)
a. Differences open vs closed:
- Closed: current flows; bulb lights. Open: circuit broken; current stops; bulb off. (3 marks; 1 each)
b. Diagram of parallel: battery with two separate branches each containing a bulb; both bulbs connected across the battery. (4 marks: correct drawing and labels)
c. In parallel each bulb has its own path to the battery; removing one bulb does not break the other bulb’s path so the other stays lit. (3)

4. Forces & machines (10)
a. Push: a force that moves something away (e.g., pushing a trolley); Pull: a force that brings something closer (e.g., pulling a rope). (2)
b. Three simple machines and examples:
- Lever: seesaw or crowbar
- Inclined plane (ramp): ramp into a truck
- Pulley: flagpole or clothesline pulley
(3; 1 mark each)
c. Ramp makes the distance longer but reduces the force needed — pushing up a ramp requires less effort than lifting directly. (3)
d. Example of energy change: electrical → light in a bulb; electrical → mechanical in a motor; chemical → heat in burning wood, etc. (2)

SECTION D (20)
1. Dissolving sugar experiment (10)
- Variable (change): water temperature (hot/warm/cold). (1)
- Kept the same: amount of sugar, amount of water, same stirring method or time per trial, same container, same size of sugar crystals. (3)
- How to measure: time how long it takes for a measured spoon of sugar to disappear or measure mass of undissolved sugar after set time or note when solution becomes clear. (2)
- Expected: sugar dissolves faster in warm/hot water than in cold water. (2)
- Safety: use caution with hot water; ask teacher or use adult help; do not touch hot containers. (1)
- Present results: table with columns (temperature, trial, time to dissolve), or a bar graph showing time vs temperature. (1)

2. Magnets picture (10)
a. Objects picked up: nails and paperclips (because they are made of iron/steel which are magnetic); coin (depends on coin material—most coins are not magnetic) so likely not picked up. Explain: magnets attract magnetic (ferrous) materials. (3)
b. Two north poles facing: they repel (push apart). (1)
c. Use of magnets at home: fridge magnets to hold notes; magnetic closures on bags; speakers, electric motors. (2)
d. Paperclip picked up; plastic not picked up because paperclip contains iron/steel which is magnetic; plastic is not magnetic. (2)
e. Safety rule: keep magnets away from electronic devices and medical devices (pacemakers), do not swallow small magnets, keep magnets away from credit cards, handle strong magnets with care to avoid fingers getting pinched. (2)
