Sample ECZ PSLE Integrated Science 4/1 Practice Questions

Try these sample questions to test your ECZ PSLE Integrated Science 4/1 exam readiness. Each question includes a detailed explanation. Start the interactive quiz above for the full 100+ question experience with AI tutoring.

1Which part of a green plant mainly takes in water and mineral salts from the soil?

A.Roots

B.Stem

C.Leaves

D.Flowers

Explanation: Roots hold the plant in the soil and take in water and dissolved mineral salts. Tiny root hairs increase the surface that touches the soil so more water can enter. The stem then carries that water up to the leaves.

2Green plants make their own food in the leaves using sunlight. What is this process called?

A.Respiration

B.Germination

C.Photosynthesis

D.Pollination

Explanation: Photosynthesis is how green plants make food. Chlorophyll in the leaves traps sunlight so carbon dioxide and water can be turned into food. Oxygen is given off as a useful by-product.

3Which two substances does a green plant take in to make food during photosynthesis?

A.Oxygen and sugar

B.Nitrogen gas and cooking oil

C.Hydrogen and table salt

D.Carbon dioxide and water

Explanation: A green plant uses carbon dioxide from the air and water from the soil. With sunlight and chlorophyll, these are changed into food. Oxygen is released, not taken in as the main raw material.

4What is the main job of chlorophyll in a leaf?

A.To store ripe seeds

B.To trap sunlight so the plant can make food

C.To carry water down to the roots

D.To attract insects for pollination

Explanation: Chlorophyll is the green pigment in leaves. It traps sunlight energy needed for photosynthesis. Without it, the leaf cannot make food from carbon dioxide and water.

5Which part of a flower produces pollen?

A.Petals

B.Sepals

C.Anthers

D.Stigma

Explanation: The anthers are the pollen-making parts of the flower. They sit on filaments so pollen can be picked up by insects or blown by wind. Pollen must later reach a stigma for pollination.

6A bee visits a flower and pollen sticks to the sticky top of the female part. What is that sticky part called?

A.Filament

B.Sepal

C.Stigma

D.Stalk

Explanation: The stigma is the sticky tip that receives pollen. After pollen lands there, a tube can grow down the style toward the ovules. That is how pollination leads on to fertilisation.

7What is pollination?

A.The joining of a seed and a fruit

B.The transfer of pollen from the anthers to the stigma

C.The falling of leaves in the dry season

D.The making of food in green leaves

Explanation: Pollination is the transfer of pollen grains from the anthers to the stigma. Wind, water, insects, birds, and some mammals can carry the pollen. Fertilisation is a later step, when a pollen grain joins an ovule.

8After pollen lands on the stigma, fertilisation in a flowering plant is best described as

A.the bursting of a fruit to scatter seeds

B.the growth of a new root from a stem cutting

C.the drying and falling of the petals

D.the joining of a pollen grain with an ovule

Explanation: In the CDC Grade 7 syllabus, fertilisation is the joining of a pollen grain with an ovule. Pollination only moves pollen to the stigma. A seed can then develop from the fertilised ovule.

9A ripe fruit bursts open and throws its seeds a short distance. Which method of seed dispersal is this?

A.Wind

B.Water

C.Explosive

D.Animal

Explanation: Explosive dispersal happens when a dry fruit splits suddenly and flings the seeds away. The CDC syllabus lists wind, animals, water, and the explosive method. Bursting pods of some beans and related plants work this way.

10Why is seed dispersal important for a plant species?

A.It stops flowers from opening

B.It spreads seeds so young plants are less crowded

C.It turns leaves yellow in the rain

D.It makes garden soil salty

Explanation: Dispersal spreads seeds away from the parent plant. Young plants then compete less for light, water, and minerals. The syllabus links this to the survival of the plant species.

About the ECZ PSLE Integrated Science 4/1 Exam

Zambia Primary School Leaving Examination Integrated Science (4/1) is the Examinations Council of Zambia Grade 7 science paper. The Ministry of Education Curriculum Development Centre Integrated Science syllabus (Grades 1–7, 2013) covers the human body, health and hygiene, the environment, plants and animals, and materials and energy, including water, air, and simple investigations. Grade 7 outcomes include digestion, disease and fruit foods, water supply and mixture separation, flowers, pollination, seeds and propagation, energy and circuits, lightning, the solar system, metals, and copper mining. The 2026 PSLE timetable sets 4/1 Integrated Science for 60 minutes from 10:30 to 11:30 on Tuesday 27 October 2026. Public and grant-aided candidates sit free; private candidates pay K100 per candidate (2026). ECZ does not publish an official item count. This OpenExamPrep bank is a free English-language four-option MCQ study aid at primary depth. It is not an official ECZ paper and does not replace classroom investigations or the official answer sheet.

Assessment

One written PSLE subject paper: 4/1 Integrated Science. Official duration is 60 minutes. ECZ does not publish a public item count. School-based primary science investigations in the CDC syllabus are not replaced by this MCQ bank.

Time Limit

60 minutes (2026 PSLE: 10:30–11:30, Tuesday 27 October 2026)

Passing Score

ECZ standardises each PSLE subject score onto a common 50–150 scale and reports Grade 7 performance in Divisions 1–4 (Division 1 = 115–150, Division 2 = 105–114, Division 3 = 99–104, Division 4 = 50–98 in a single subject). Certification is calculated from the best four core subjects, which must include Mathematics and English. ECZ does not publish a separate percentage cut score for this paper.

ECZ PSLE Integrated Science 4/1 Study Tips from Top Performers

1Learn the Grade 7 digestive path: mouth, stomach, small intestine (nutrients), large intestine (water and minerals), and undigested food leaving as faeces.

2Practise naming flower parts and the difference between pollination (pollen to stigma) and fertilisation (pollen joining an ovule).

3Revise water treatment used in Zambia: boiling, filtration, decantation, and chlorination, plus turning taps off to conserve water.

4Build a simple cell–switch–bulb circuit and compare series (one path) with parallel (separate paths).

5Link day and night to Earth’s rotation and seasons to Earth’s revolution on a tilted axis; June is winter and October is summer in Zambia on the CDC syllabus.

6Know copper’s uses and that mining can pollute air, land, and water; keep classroom investigations fair by changing only one variable.
