Updated 6 November 2026. This guide replaces our earlier general essay-writing article with advice for P5 and P6 Science learners.
A clear Science answer connects what the question shows to the scientific idea that explains it. Your child does not need an argumentative essay, a long introduction or impressive vocabulary. They need an accurate answer to the specific question, with enough detail to make their reasoning clear.
Start with the question, not a memorised sentence
Read the instruction carefully. A question asking a child to state an observation needs a different response from one asking them to explain a result. Identify the objects, conditions and evidence in the question before choosing a concept.
At Bestminds Academy, Observe, Analyse, Communicate (OAC) is a teaching approach for organising this thinking. It is not an official SEAB marking formula, and not every question needs three separate sentences.
1. Observe: identify the relevant evidence
Look closely at the diagram, table, graph or description. Ask: What changed? What was measured? Which comparison answers the question? Include relevant values and units when using data. Do not invent an observation that the question does not provide.
2. Analyse: connect the evidence to a Science concept
Choose the idea that explains the result. Then work through the cause and effect. Naming a concept such as heat transfer or evaporation is only a starting point. Explain how that concept applies to the objects and conditions in this question.
3. Communicate: make the reasoning clear
Name the object rather than repeatedly writing “it”. Use accurate scientific terms and connect each step logically. Words such as “because”, “so” and “therefore” help only when the scientific relationship is correct.
A worked example: explaining a warmer spoon
Illustrative practice example, not a past PSLE question: A metal spoon is placed in hot water. Its handle becomes warmer. Explain why.
Incomplete answer: “Metal is a good conductor of heat.”
Clearer answer: “Heat is transferred from the hotter water to the metal spoon and conducted along the spoon to its cooler handle, so the handle becomes warmer.”
The clearer answer identifies where the heat comes from, its direction of transfer and the result. It explains this situation instead of stopping at a memorised property.
A worked example: describing data accurately
Illustrative practice example: In three trials under the same conditions, a toy car travels 40 cm, 42 cm and 41 cm on surface A, and 20 cm, 21 cm and 19 cm on surface B.
If asked to compare the distances, a relevant response is: “The toy car travelled farther on surface A than on surface B in all three trials.” If asked to explain the difference, your child must also consider the information given about the surfaces and the forces involved. The measurements alone do not establish every possible cause.
A short checking routine
- Have I answered the instruction and every part of the question?
- Have I used the relevant evidence rather than copied the whole question?
- Are the Science concept and direction of cause and effect correct?
- Can a reader tell which object each sentence refers to?
- Have I removed irrelevant details and unsupported claims?
How parents can help
Ask “What in the question supports that?” and “What happens next, and why?” Give your child time to explain before offering a correction. If you are unsure of the Science, check the school material or ask the teacher. Practise improving one explanation at a time, rather than demanding longer answers.
For examination requirements, refer to the official SEAB PSLE examination formats. Answer length alone does not determine marks.
