Reproduction in Plants & Animals
Understand plant and human reproduction processes, cell structures, pollination, fertilisation, and how genetic traits are inherited.
PSLE Science evaluates students on both content knowledge and process skills. The paper is split into Booklet A (28 MCQs, 56 marks) and Booklet B (12 Open-ended questions, 44 marks). Students must study five key domains: Cycles, Systems, Energy, Interactions, and cross-cutting Scientific Inquiry skills.
Understand plant and human reproduction processes, cell structures, pollination, fertilisation, and how genetic traits are inherited.
Study the water cycle, processes of melting, boiling, evaporation, and condensation, and how heat exchange drives states of matter changes.
Explore xylem and phloem tube systems in plants. Understand how water, mineral salts, and food are transported throughout the plant organism.
Master human respiratory and circulatory organs. Learn how the heart, lungs, and blood vessels collaborate to transport oxygen and nutrients.
Understand open vs closed circuits, conductors, insulators, and the differences in bulb brightness in series and parallel circuit configurations.
Study the raw materials and products of photosynthesis, factors affecting its rate, and how plant respiration compares to it.
Identify six key forms of energy and trace energy conversions in various appliances, mechanical toys, and falling objects.
Explore gravitational, frictional, magnetic, and elastic spring forces. Learn how forces affect motion, shape, and direction of objects.
Learn about food webs, energy transfer in trophic levels, animal adaptations, structural vs behavioral features, and environmental balance.
Essential exam strategies for Booklet B open-ended questions. Learn variables control, hypothesis writing, and scientific reasoning structures.
Booklet B questions require the Claim-Evidence-Reasoning (CER) framework or the O-R-E (Observation, Recall, Explanation) technique. Students must identify the scientific concept, state the evidence from the diagram or table, and explain the science reasoning clearly using proper keywords.
The syllabus covers five main strands: Cycles (reproduction, water cycles), Systems (circulatory, respiratory, electrical, plant transport), Energy (photosynthesis, energy conversions), Interactions (forces, environment), and Scientific Inquiry.
Experimental questions test variables. Students must be able to state the Aim of the experiment, identify the Independent Variable (changed), Dependent Variable (measured), and Constant Variables (kept the same for a fair test).
