The BEC PSLE Science examination assesses Standard 7 students in Botswana on foundational science concepts and practical process skills. The exam covers 7 key topics: living things, human body, hygiene, materials, energy, weather, and solar system. The 100 questions on this page are an English-language MCQ study adaptation, not an official BEC paper simulation.

1Which component of a green plant is primarily responsible for absorbing water and dissolved mineral salts from the soil?
A.Roots
B.Stem
C.Leaves
D.Flowers
Explanation: Roots anchor the plant in the soil and absorb water and dissolved mineral salts necessary for growth. Root hairs significantly increase the surface area to maximize absorption efficiency. Once absorbed, water and minerals move upward through xylem vessels in the stem to reach the leaves.
2What primary green pigment in plant leaves absorbs light energy for photosynthesis?
A.Xanthophyll
B.Chlorophyll
C.Carotene
D.Hemoglobin
Explanation: Chlorophyll is the green pigment located within chloroplasts in plant cells. It traps sunlight energy needed to convert carbon dioxide and water into glucose and oxygen during photosynthesis. Without chlorophyll, plants cannot perform photosynthesis.
3Which of the following organisms is classified as a decomposer in an ecosystem?
A.Acacia tree
B.Impala
C.Mushroom
D.Eagle
Explanation: Mushrooms (fungi) are decomposers that break down dead plant and animal organic matter into simpler nutrients. This process recycles essential minerals back into the soil for use by producers. Decomposers play a vital role in nutrient cycling in all ecosystems.
4What is the term for animals that eat only plants?
A.Carnivores
B.Herbivores
C.Omnivores
D.Decomposers
Explanation: Herbivores are animals whose diets consist exclusively of plant matter such as leaves, grass, seeds, and fruits. Examples in Botswana include elephants, zebras, giraffes, and impalas. Their digestive systems are specially adapted to break down plant fiber.
5Which seed dispersal mechanism is utilized by plants with light, winged, or feathery seeds such as dandelions?
A.Water dispersal
B.Animal dispersal
C.Wind dispersal
D.Self-explosive dispersal
Explanation: Wind dispersal occurs in plants whose seeds are lightweight or equipped with wing-like or parachute-like structures. These features allow air currents to carry the seeds over long distances away from the parent plant, reducing competition for resources.
6Which structural feature helps desert plants like cacti reduce water loss in arid environments?
A.Broad, thin leaves
B.Spines instead of leaves
C.Fleshless, woody stems
D.Shallow, sparse roots
Explanation: Cacti have modified leaves called spines, which dramatically reduce surface area and limit water loss through transpiration. Spines also protect the plant from herbivorous animals looking for moisture. Photosynthesis is carried out by the thick, green, succulent stem.
7In a savanna food chain consisting of grass -> impala -> cheetah, which organism acts as the primary consumer?
A.Grass
B.Impala
C.Cheetah
D.Decomposing bacteria
Explanation: The impala is the primary consumer because it feeds directly on the producer (grass). Primary consumers are herbivores that occupy the second trophic level in a food chain.
8What process occurs when pollen is transferred from the anther to the stigma of a flower?
A.Germination
B.Pollination
C.Fertilization
D.Dispersal
Explanation: Pollination is the transfer of pollen grains from the male anther to the female stigma of a flower. It can be carried out by wind, insects, birds, or water. Once pollination occurs, the pollen grain grows a tube down to the ovary for fertilization.
9Which statement correctly describes a key difference between insects and spiders?
A.Insects have 8 legs, while spiders have 6 legs.
B.Insects have 3 main body segments, while spiders have 2 main body segments.
C.Insects have no antennae, while spiders have two pairs of antennae.
D.Insects possess an exoskeleton, while spiders have an internal bony skeleton.
Explanation: Insects have 3 distinct body parts (head, thorax, abdomen) and 6 jointed legs. Spiders (arachnids) have 2 main body parts (cephalothorax and abdomen) and 8 jointed legs.
10During seed germination, which part of the embryo emerges FIRST through the seed coat?
A.Plumule (young shoot)
B.Radicle (young root)
C.Cotyledon (seed leaf)
D.Flower bud
Explanation: The radicle (embryonic root) breaks through the seed coat first to anchor the seedling in the soil and begin absorbing water and minerals. The plumule (embryonic shoot) emerges afterwards to grow upward toward light.

About the PSLE Science Exam

The Botswana Primary School Leaving Examination (PSLE) Science test is a standardized national examination for Standard 7 primary school students in Botswana. Conducted annually by the Botswana Examinations Council (BEC), it tests candidates across key domains including Living Things, Human Body, Hygiene, Materials, Energy, Weather, and the Solar System, evaluating both conceptual knowledge and scientific process skills.

Exam sponsor: Botswana Examinations Council (BEC). The requirements and fees below concern the certification or admission exam, separate from our free practice resources.

Assessment

National PSLE Science written examination administered by BEC under the seven-subject Primary School Leaving Examination scheme

Time Limit

Scheduled annually by BEC: Letter and Composition for English and Setswana in August; remaining PSLE papers in October (exact subject durations are published in that year's PSLE timetable)

Passing Score

Grades A to E; Grade C or better is commonly treated as a credit standard

Exam / Certification Fees

BEC private-candidate fees are published annually; the 2023 BEC schedule was P100.00 per syllabus (confirm current fees on bec.co.bw). Public-school candidates are registered through their centre.

Frequently Asked Questions

What is the PSLE Science exam in Botswana?

The Primary School Leaving Examination (PSLE) Science exam is a national assessment administered by the Botswana Examinations Council (BEC) to Standard 7 primary school learners across Botswana. It evaluates students' scientific knowledge and application skills before transitioning to Junior Secondary School.

What topics are covered on the BEC PSLE Science exam?

The syllabus covers seven primary content areas: Living Things (plants, animals, ecosystems), Human Body (organ systems), Hygiene & Health (disease prevention, sanitation), Materials (states of matter, properties), Energy & Forces (heat, light, electricity, forces), Weather & Water (water cycle, weather instruments), and Solar System & Earth (planets, rotation, moon phases).

How is the PSLE Science exam structured?

The exam consists of Paper 1 (60 multiple-choice questions testing knowledge and application) and Paper 2 (structured open-ended questions requiring written explanations, diagrams, and data interpretation).

What grade is required to pass PSLE Science in Botswana?

PSLE performance is reported in grades A through E. Grade C or higher is considered a credit pass and is required for strong placement in government junior secondary schools.

What scientific process skills are tested on the PSLE Science exam?

Candidates are assessed on process skills including observing, measuring, classifying, predicting, inferring, communicating data through tables and graphs, and designing simple experiments.

How can Standard 7 students prepare effectively for PSLE Science?

Students should review the BEC syllabus, practice multiple-choice questions with detailed explanations, master key scientific terms, memorize weather instruments and body system functions, and study common diseases in Botswana like malaria and bilharzia.

Are these official BEC examination questions?

No. These are original English-language multiple-choice study questions aligned to Botswana PSLE subject outcomes. They are a study adaptation and do not simulate the official BEC papers or mark schemes.
