Section A: Multiple-Choice Questions (20 marks)

Question 1 [2 marks]

Answer: (1)

Explanation:

Mushroom (fungus), moss (non-flowering plant), and fern (non-flowering plant) are all living things.
Option (2): Crystal is non-living; coral is an animal (living); sponge could be natural (living) or synthetic (non-living) — not all living.
Option (3): Cloud, river, rock are all non-living.
Option (4): Robot, car, computer are all non-living (man-made objects).

Key concept: Living things include plants, animals, fungi, and microorganisms. Non-living things include natural objects (rocks, water) and man-made objects.

Question 2 [2 marks]

Answer: (1)

Explanation:

Group A: Bat, Whale, Human — all are mammals (have hair/fur, give birth to live young, feed young with milk, breathe with lungs).
Group B: Eagle, Penguin, Ostrich — all are birds (have feathers, lay eggs, have beaks, breathe with lungs).
Option (2) is incorrect because it describes a characteristic, not the group name.
Option (3) describes characteristics but not the classification group names.
Option (4) is incorrect because both mammals and birds breathe with lungs.

Key concept: Classification groups (mammals, birds, fish, reptiles, amphibians) are based on multiple shared characteristics, not just one.

Question 3 [2 marks]

Answer: (2)

Explanation:

Ali is incorrect: Fungi cannot make their own food. They are decomposers that obtain nutrients by breaking down dead or decaying organic matter.
Bala is correct: Fungi reproduce by spores (e.g., mushrooms release spores from gills).
Cindy is incorrect: Not all fungi are harmful. Some are useful (yeast for bread/beer, penicillin from mold, edible mushrooms).
Devi is incorrect: Fungi do not need sunlight to grow. They grow in dark, damp places.

Key concept: Fungi are a separate kingdom from plants. They do not photosynthesise.

Question 4 [2 marks]

Answer: (1)

Explanation:

Roots absorb water and mineral salts from the soil. They have root hairs that increase surface area for absorption.
Stem: Transports water and food, supports the plant.
Leaves: Make food through photosynthesis.
Flowers: Reproductive parts (produce seeds and fruits).

Key concept: Each plant part has a specific function. Roots = absorption + anchorage.

Question 5 [2 marks]

Answer: (2)

Explanation:

All living things: Need air, food, and water; respond to changes; grow and reproduce.
Not all living things can move from place to place: Plants are living but generally cannot move from place to place (they move parts like leaves/flowers but not locomotion).
This is a common misconception — movement is not a defining characteristic of all life.

Key concept: The 5 characteristics of living things: (1) Need air, food, water (2) Grow (3) Respond to changes (4) Reproduce (5) Eliminate waste. Locomotion is not universal.

Question 6 [2 marks]

Answer: (3)

Explanation:
Following the flowchart:

Is it a living thing? Yes
Does it make its own food? No (it's an animal)
Does it have feathers? No
Does it have hair/fur? No
Does it have scales and breathe with gills? No (breathes with lungs)
Does it have moist skin and lay eggs in water? No (dry scaly skin)
→ Reptile

Reptiles have dry scaly skin, breathe with lungs, and most lay eggs on land.

Key concept: Vertebrate classification: Fish (gills, scales, water), Amphibians (moist skin, eggs in water), Reptiles (dry scales, lungs, eggs on land), Birds (feathers, lungs, eggs), Mammals (hair/fur, lungs, live birth mostly).

Question 7 [2 marks]

Answer: (1)

Explanation:
Butterfly undergoes complete metamorphosis:
Egg → Larva (caterpillar) → Pupa (chrysalis) → Adult (butterfly)

Option (2) shows incomplete metamorphosis (e.g., grasshopper, cockroach).
Options (3) and (4) have incorrect stage orders.

Key concept: Complete metamorphosis has 4 distinct stages with a pupal stage. Incomplete metamorphosis has 3 stages (egg, nymph, adult) with no pupal stage.

Question 8 [2 marks]

Answer: (3)

Explanation:

Wood, metal, and plastic are all solids at room temperature.
Solids have definite shape and definite volume.
(1) Not all are flexible (metal spoon, wooden block are rigid).
(2) Wood is not waterproof (absorbs water).
(4) Only iron/steel is magnetic; wood and plastic are not.

Key concept: Properties of solids: definite shape, definite volume, cannot be compressed (much). This is true for all solids regardless of material.

Question 9 [2 marks]

Answer: (3)

Explanation:

Independent variable (changed): Amount of water (dry vs. wet cotton wool).
Dependent variable (measured): Whether seeds germinate.
Controlled variables (kept same): Type of seeds (green bean), number of seeds (5), type of container, location (warmth).

Key concept: A fair test changes only one variable (independent) while keeping all others constant (controlled) to see the effect on the outcome (dependent).

Question 10 [2 marks]

Answer: (2)

Explanation:

Matter = anything that has mass and occupies space.
Air, water, sand all have mass and occupy space → matter.
(1) Light, heat, sound are forms of energy, not matter.
(3) Shadow, rainbow, electricity are not matter (shadow = absence of light; rainbow = light phenomenon; electricity = energy).
(4) Time, space, energy are abstract concepts/physical quantities, not matter.

Key concept: Matter exists in three states: solid, liquid, gas. All have mass and volume. Energy and phenomena are not matter.

Section B: Open-Ended Questions (30 marks)

Question 11 [3 marks]

(a) [2 marks]

Living Things	Non-Living Things
W, X, Y	Z

W (Cat) = Animal → Living
X (Mushroom) = Fungus → Living
Y (Fern) = Plant → Living
Z (Rock) = Non-living

Marking: 1 mark for correct living things (all 3 letters), 1 mark for correct non-living thing (Z). No half marks.

(b) [1 mark]
Any one of:

The rock does not need air, food, and water.
The rock does not grow.
The rock does not respond to changes.
The rock does not reproduce.
The rock does not eliminate waste.

Key concept: Living things show all characteristics of life; non-living things do not.

Question 12 [3 marks]

(a) [1 mark]
Any one of:

Both are vertebrates (have a backbone).
Both breathe with lungs.
Both are warm-blooded (maintain constant body temperature).
Both give birth to young / lay eggs (but this differs — see below).

Best answer: Both are vertebrates / Both breathe with lungs.

(b) [2 marks]
A whale is a mammal because:

It breathes with lungs (not gills like fish) — must surface to breathe air.
It gives birth to live young (does not lay eggs like most fish).
It feeds its young with milk (mammary glands).
It has hair (though very little, e.g., whiskers at birth).
It is warm-blooded.

Marking: 1 mark for stating a correct mammalian characteristic (e.g., breathes with lungs, gives birth to live young, feeds young with milk, has hair). 1 mark for explaining why this makes it different from fish (e.g., fish have gills, lay eggs, no milk).

Common mistake: Saying "whale lives in water so it's a fish" — habitat does not determine classification.

Question 13 [4 marks]

(a) [1 mark]
Pupa (or chrysalis/tumbler)

(b) [1 mark]
Any one difference:

Larva lives in water (wriggler); adult lives on land/flies.
Larva has no wings; adult has wings.
Larva feeds on microorganisms in water; adult feeds on nectar/blood (female).
Larva is worm-like; adult has distinct head, thorax, abdomen, legs, wings.
Larva breathes through siphon tube at water surface; adult breathes through spiracles.

(c) [2 marks]
Stagnant water is the breeding ground for mosquitoes.

Mosquitoes lay eggs in stagnant water.
Larva and pupa stages develop in water.
Removing stagnant water prevents mosquitoes from breeding, reducing the spread of diseases like dengue, malaria, Zika.

Marking: 1 mark for identifying stagnant water as breeding site. 1 mark for linking to disease prevention / stopping life cycle.

Key concept: Breaking the life cycle at the aquatic stages controls mosquito population.

Question 14 [4 marks]

(a) [2 marks]
Material: Rubber (Object A)
Reason: Rubber is flexible and waterproof.

Flexible → comfortable to wear, allows movement.
Waterproof → keeps rain out, keeps wearer dry.

Marking: 1 mark for correct material (Rubber/A). 1 mark for reason linking both properties (flexible + waterproof) to function.

(b) [2 marks]
Material: Glass (Object B)
Reason: Glass is transparent and waterproof.

Transparent → allows light to pass through so we can see outside.
Waterproof → keeps rain/wind out.

Marking: 1 mark for correct material (Glass/B). 1 mark for reason linking transparency (essential) and waterproof to function.

Key concept: Material choice depends on matching properties to the object's function.

Question 15 [4 marks]

(a) [1 mark]
Any one function of stem:

Transports water and mineral salts from roots to leaves.
Transports food (sugar) from leaves to other parts of the plant.
Supports the plant (holds leaves up to sunlight, holds flowers/fruits).

(b) [2 marks]
Two things leaves need to make food (photosynthesis):

Sunlight (light energy)
Carbon dioxide (from air)
(Water is also needed but is transported from roots via stem; the question asks what leaves need — sunlight and carbon dioxide are taken in at the leaves.)

Marking: 1 mark each for sunlight and carbon dioxide. Water from roots is accepted but less precise for "what leaves need".

(c) [1 mark]
Damaged roots cannot absorb water and mineral salts from the soil.
Without water, the plant cannot:

Make food (photosynthesis needs water)
Transport nutrients
Stay upright (wilting)
Carry out life processes → plant dies.

Key concept: Roots are essential for water/mineral uptake. No water = no photosynthesis = no food = death.

Question 16 [4 marks]

(a) [1 mark]
To find out how the amount of light affects the growth of a plant.
(Or: To investigate the effect of light duration on plant growth.)

(b) [2 marks]
Setup P (8 hours sunlight) is the control.
Explanation: It represents the normal/natural condition for plant growth (full sunlight). The other setups (Q and R) have reduced light to compare against this normal condition.

Marking: 1 mark for identifying Setup P. 1 mark for explaining it represents normal/optimal condition for comparison.

Note: In experiments testing "effect of X", the control is usually the standard/normal level of X.

(c) [1 mark]
Any one controlled variable:

Type of plant
Size/age of plant at start
Type and amount of soil
Size/type of pot
Amount of water given
Temperature/location (except light)
Type of container

Key concept: Fair test = only independent variable (light duration) changes; all others kept constant.

Question 17 [4 marks]

(a) [1 mark]
W and Z (both have definite shape, definite volume, cannot be compressed → solids)

(b) [1 mark]
Y (no definite shape, no definite volume, can be compressed → gas)

(c) [2 marks]
Shape: Changes (takes the shape of the wide container)
Volume: Remains the same (stays the same / does not change)

Explanation:

Material X is a liquid (no definite shape, definite volume, cannot be compressed).
Liquids take the shape of their container → shape changes when poured.
Liquids have definite volume → volume does not change when poured.

Marking: 1 mark for shape change, 1 mark for volume unchanged.

Key concept: Properties of states of matter:

Solid: definite shape, definite volume
Liquid: no definite shape (takes container shape), definite volume
Gas: no definite shape, no definite volume (fills container), compressible

Question 18 [4 marks]

(a) [2 marks]
Light: Not matter (does not have mass, does not occupy space)
Water: Matter → Liquid (has mass, occupies space, no definite shape, definite volume)

Marking: 1 mark each for correct classification.

(b) [1 mark]
Any one property of a solid:

Has a definite shape
Has a definite volume
Cannot be compressed (or very difficult to compress)
Particles are tightly packed in fixed positions

(c) [1 mark]
Air (gas) can be compressed / does not have a definite volume.
(Or: Air occupies space and has volume, but its volume can be reduced when pressure is applied.)

Explanation: Gases have no definite volume — their particles are far apart and can be pushed closer together (compressed). When the plunger is pushed in, the same amount of air occupies a smaller volume.

Key concept: Compressibility is a key property distinguishing gases from solids and liquids.
