Integrated Science · Living things — Adaptation

Practice question 1

Plants near school canteen have waxy leaves. Which explanation is most reasonable?

  1. Waxy leaves prove plants need no water.
  2. The feature guarantees survival everywhere.
  3. Waxy leaves prevent all light reaching the plant.
  4. The waxy surface may reduce water loss.
Show answer and explanation

Answer: D. The waxy surface may reduce water loss.

A waxy cuticle can reduce water loss, though other factors also matter.

Integrated Science · Living things — Adaptation

Practice question 2

Plants near clean-up have waxy leaves. Which explanation is most reasonable?

  1. Waxy leaves prove plants need no water.
  2. The waxy surface may reduce water loss.
  3. The feature guarantees survival everywhere.
  4. Waxy leaves prevent all light reaching the plant.
Show answer and explanation

Answer: B. The waxy surface may reduce water loss.

A waxy cuticle can reduce water loss, though other factors also matter.

Integrated Science · Materials — Properties

Practice question 3

A container at school canteen must hold water and be carried safely. What should guide material choice?

  1. Choose only the brightest material.
  2. Compare strength, leakage, mass, durability and safe use.
  3. Assume all materials behave alike.
  4. Ignore whether it leaks.
Show answer and explanation

Answer: B. Compare strength, leakage, mass, durability and safe use.

Material choice depends on purpose and relevant properties.

Integrated Science · Energy — Efficiency

Practice question 4

Lights are left on in an empty room at school canteen. Which action directly reduces wasted electricity?

  1. Leave all lights on all day.
  2. Cover windows and add lamps.
  3. Switch off unnecessary lights and use daylight where practical.
  4. Replace bulbs but never switch them off.
Show answer and explanation

Answer: C. Switch off unnecessary lights and use daylight where practical.

Avoiding unnecessary use reduces energy waste.

Integrated Science · Forces — Friction

Practice question 5

A toy vehicle travels farther on a smooth floor than on rough ground near school canteen. Which explanation fits?

  1. Gravity stops acting on the smooth floor.
  2. The rough surface likely creates more friction opposing motion.
  3. Roughness always adds energy.
  4. The vehicle has no mass.
Show answer and explanation

Answer: B. The rough surface likely creates more friction opposing motion.

Friction between surfaces can reduce travel distance.

Integrated Science · Safety — Risk assessment

Practice question 6

A group finds an unknown cleaning liquid at school canteen. What should it do?

  1. Taste a drop to identify it.
  2. Mix it with another cleaner.
  3. Do not taste or mix it; check the label and ask a teacher while following safety procedures.
  4. Handle it bare-handed without supervision.
Show answer and explanation

Answer: C. Do not taste or mix it; check the label and ask a teacher while following safety procedures.

Unknown substances may be hazardous and require safe identification.

Integrated Science · Investigation — Fair testing

Practice question 7

Learners test whether sunlight affects seedlings at school canteen. Which method is fairest?

  1. Change sunlight while keeping seed type, soil, water and container similar.
  2. Change sunlight, water and soil together.
  3. Use one seedling to represent all plants.
  4. Measure plants under different conditions without recording them.
Show answer and explanation

Answer: A. Change sunlight while keeping seed type, soil, water and container similar.

A fair test changes one main factor and controls other variables.

Integrated Science · Earth and space — Observation

Practice question 8

Learners record shadows at bus journey at several times in a day. What is most likely?

  1. Shadows stay identical all day everywhere.
  2. Shadow length and direction change as the Sun's apparent position changes.
  3. The Sun circles Earth once every hour.
  4. Shadows change only when object colour changes.
Show answer and explanation

Answer: B. Shadow length and direction change as the Sun's apparent position changes.

The angle of sunlight changes during the day due to Earth's rotation.
