KS2 SATs KS2 Science 5 — Questions and Answers
Question 1: What is the name for animals that feed on both plants and animals?
- Herbivores
- Carnivores
- Omnivores (Correct answer)
- Decomposers
Correct answer: Omnivores
Omnivores eat both plant material and animal matter. Humans, bears, and pigs are examples of omnivores. The word comes from Latin: 'omni' (all) + 'vorare' (to eat).
Question 2: What is the correct equation for photosynthesis?
- Glucose + Oxygen → Carbon dioxide + Water
- Carbon dioxide + Water → Glucose + Oxygen (Correct answer)
- Oxygen + Water → Carbon dioxide + Glucose
- Glucose + Water → Oxygen + Carbon dioxide
Correct answer: Carbon dioxide + Water → Glucose + Oxygen
The equation for photosynthesis is: Carbon dioxide + Water (+ light energy) → Glucose + Oxygen. Plants use CO₂ from air and H₂O from soil to make glucose, releasing O₂ as a by-product.
Question 3: What type of rock can contain fossils?
- Igneous
- Metamorphic
- Sedimentary (Correct answer)
- All types of rock
Correct answer: Sedimentary
Fossils are found in sedimentary rock, which forms from layers of sediment (sand, mud, shells) that compress over millions of years. The soft layers preserve remains of organisms.
Question 4: What is the unit of force?
- Kilogram (kg)
- Metre (m)
- Newton (N) (Correct answer)
- Joule (J)
Correct answer: Newton (N)
Force is measured in Newtons (N), named after Sir Isaac Newton. A Newton is the amount of force needed to accelerate a 1 kg mass at 1 metre per second squared. Weight is also measured in Newtons.
Question 5: What is the name for the process by which water moves from the sea to clouds to rain?
- The oxygen cycle
- The water cycle (or hydrological cycle) (Correct answer)
- The nitrogen cycle
- The carbon cycle
Correct answer: The water cycle (or hydrological cycle)
The water cycle (hydrological cycle) describes the continuous movement of water: evaporation from sea/land, condensation to form clouds, precipitation as rain or snow, and runoff back to the sea.
Question 6: Which sense organ detects light and allows us to see?
- Ear
- Tongue
- Skin
- Eye (Correct answer)
Correct answer: Eye
The eyes are the sense organs that detect light. Light enters the eye through the pupil, is focused by the lens onto the retina, which contains receptor cells that send signals to the brain.
