KS2 SATs Science Sampling — Questions and Answers
Question 1: Which part of a plant is responsible for absorbing water and minerals from the soil?
- Stem
- Leaves
- Roots (Correct answer)
- Flowers
Correct answer: Roots
Roots absorb water and minerals from the soil. They have root hairs that increase the surface area for absorption.
Question 2: What happens to water when it is heated to 100°C at normal atmospheric pressure?
- It freezes
- It evaporates
- It boils (Correct answer)
- It condenses
Correct answer: It boils
Water boils at 100°C at normal atmospheric pressure. Boiling is when a liquid changes to a gas throughout the liquid, not just at the surface (which is evaporation).
Question 3: Which of these is NOT a property of metals?
- Good conductor of electricity
- Malleable
- Brittle (Correct answer)
- Shiny when polished
Correct answer: Brittle
Most metals are not brittle — they are malleable (can be bent or hammered into shape) and ductile. Brittleness is a property of many non-metals like ceramics or glass.
Question 4: What force pulls objects towards the centre of the Earth?
- Friction
- Air resistance
- Gravity (Correct answer)
- Magnetism
Correct answer: Gravity
Gravity is the force that pulls all objects with mass towards each other. On Earth, it pulls everything towards the centre of the planet.
Question 5: In an electrical circuit, what does a switch do?
- Provides energy to the circuit
- Breaks or completes the circuit (Correct answer)
- Measures the current
- Increases the voltage
Correct answer: Breaks or completes the circuit
A switch controls whether the circuit is complete (closed) or broken (open). When open, current cannot flow; when closed, the circuit is complete and current flows.
Question 6: Which planet in our solar system is closest to the Sun?
- Venus
- Earth
- Mercury (Correct answer)
- Mars
Correct answer: Mercury
Mercury is the closest planet to the Sun, orbiting at an average distance of about 58 million kilometres.
