PSLE Science Learning Guide | Questions, Evidence, Investigations & Revision

Science Hub · Primary Science · PSLE learning guides

You do not need to read every Science guide today. You need to find the next thing you cannot yet do independently.

This PSLE Science Learning Guide brings the eduKate Sengkang learning-guide series into one place. Start with the roadmap, choose the learning problem you recognise, and open the guide that addresses it. The original articles remain separate: reading a question, planning a fair test, describing evidence and explaining a mechanism are related skills, but they are not the same task.

Apply the skills to real-world claims: PSLE Science Reality Lab — evaluate labels, graphs, headlines, ratings, images and scientific claims using evidence and inquiry reasoning.

Choose your next learning route

Bring a recent question, your first answer and the feedback you received. Ask where the answer first went wrong. Was the concept missing? Was the question misread? Did the comparison change? Did the explanation claim more than the evidence showed? Use that first difficulty to choose a route below.

Newest guides · Scope and official references · Parent and tutor teaching guide

Catalogue check: 7 September 2026. The ten sections below organise PSLE Science guides by the learning problem they address. New posts assigned to the category appear in the newest-guides section and the full archive; the organised index is a dated snapshot.

1. Start here: roadmap and Science themes

Begin here when the difficulty is not one question but knowing how to learn the subject. Start with the Primary 5-to-PSLE roadmap, build a repeatable learning cycle, and use the theme guides to connect ideas. These guides organise learning; the separate Primary Science course guide remains the place to browse the wider course.

Try next: Choose one idea from a theme you have studied. Explain it without your notes, use it in a different example, then compare your response with your learning materials. Let the difficulty you discover choose the next guide.

2. Question reading and command words

Use this route when you know the topic but answer a different question, miss a second instruction, reverse a comparison or assume a word means more than it says. Before writing the Science, identify what the question asks you to produce and which conditions it gives you.

Browse all 10 question-reading guides

Try next: Before answering an unfamiliar question, say: “I have to find or explain ___, using ___, under these conditions: ___.” Keep this as a practice prompt, not a compulsory sentence to copy into an examination answer.

3. Evidence and clear scientific explanations

Use this route when an answer contains true facts but does not explain the result, when scientific keywords appear without a connection, or when an evidence question receives only a remembered mechanism. Keep the object, observation, relevant concept and requested explanation connected.

Browse all 20 evidence and explanation guides

Try next: In a practice answer, underline the part taken from the evidence and circle the part supplied by your scientific knowledge. Check whether the question needs both, or only one of those jobs.

4. Investigations, variables and fair tests

Use this route when you lose track of what is changed, what is measured, what is kept consistent or what a comparison can establish. Begin with the investigation question. Then follow the design through its variables, measurements and results before deciding what can be concluded.

Browse all 27 investigation guides

Try next: Label one set-up with its question, changed condition, measured outcome and comparison. Then count trials, specimens and measurements separately. Several readings from one run do not automatically mean the whole investigation was repeated several times.

5. Data, tables, graphs and change

Use this route when a number has the wrong role in your answer, a graph is read by appearance alone, or a trend is simplified until part of the evidence disappears. Identify what each row, axis and value represents before comparing. Keep a starting value, an amount of change and a final value separate.

Browse all 32 data, table and graph guides

Try next: A quantity starts at 12 units and increases to 20 units. Its final value is 20 units; its increase is 8 units. Now change the sentence to “increases by 20 units” and work out what has changed. This is a reading exercise before it is a scientific explanation.

6. Measurement, units and precision

Use this route when the question concerns what to measure, where or when to measure it, which instrument to choose, or what a reading can actually establish. Do not let the presence of a number make the evidence more precise than the method allows.

Browse all 15 measurement guides

Try next: Name the quantity, unit, instrument, location and time of one reading. Then say which parts were directly observed and which were calculated. A useful answer should preserve those roles.

7. Diagrams, models and classification keys

Use this route when the illustration seems familiar but its meaning is uncertain. A picture may represent a view, a sequence, a simplified system or a model. Read labels, arrows, keys and scale information before treating the drawing as evidence.

Browse all 15 diagram, model and classification guides

Try next: Describe what a diagram represents before naming the topic. Then identify one feature the drawing tells you and one feature it does not establish. This keeps interpretation attached to the information supplied.

8. Reasoning, relationships and causation

Use this route when several explanations seem possible, a result is unexpected, a condition changes, or a conclusion goes beyond what was tested. Describe the evidence first. Then decide what scientific reasoning is justified. A relationship statement and a causal explanation should not be merged merely because both appear in the same investigation.

Browse all 35 reasoning and causation entries

Try next: Write two separate practice sentences: “The evidence shows ___” and “The scientific explanation is ___.” Then check whether the design and information justify the second sentence. When the task asks only for the relationship, do not add an unsupported cause.

9. Multiple-choice, open-ended and examination craft

Use this route when understanding is available during a lesson but harder to use independently, under time pressure or among competing answer choices. Work on the particular task: evaluating a statement, completing every part, returning to a skipped question or checking an answer for a reason.

Browse all 17 examination-practice guides

Try next: Compare an untimed answer with a later timed response to a similar task. Record what changed: reading, selection, explanation, completion or checking. Use that observation to choose practice, rather than labelling every error “careless”.

10. Revision, retrieval, correction and transfer

Use this route when revision means rereading familiar pages but the same difficulty returns in a new question. Choose one error pattern, study the relevant idea, attempt it without the answer in view, and return to it later in a changed context. The point is not a perfectly copied correction; it is an explanation you can produce yourself.

Browse all 32 revision and correction guides

Try next: Write one specific correction target: “I will identify the starting value before comparing changes,” rather than “I will be more careful.” Test that target on a different question, then return to it after a gap.

New PSLE Science learning guides — 5 September 2026

These recent guides extend the hub through four learning routes. Choose the route that matches the first place your reasoning breaks down, then return to a changed question and try the skill independently.

Data, tables, graphs and comparison

Investigations, conditions and method

Diagrams, processes and systems

Revision and transfer

Further PSLE Science learning guides — 6 September 2026

Choose the difficulty you recognise. These twenty guides extend the earlier collection; the four learning sequences below connect them to related guides from previous batches.

Read objects, conditions and comparisons

Trace investigations and results

Build explanations and test MCQ claims

Diagnose a difficulty and return independently

Four connected learning sequences

Keep the object and its evidence together: Start with paired labels and values, continue to reference words, then changing names for the same object, and finish by checking conditions in captions and headings.

Follow an investigation from conditions to evidence: Begin with the condition set and the condition experienced, distinguish the deliberate change from the response, identify outcome measurements and checks on controlled conditions, then use an observation to form a testable follow-up question.

Build an explanation that responds to evidence: Follow a process with different possible outcomes, identify what each condition does, complete the missing links around a supplied middle step, and check what new evidence changes.

Return to independent practice: Begin by connecting ideas across topics. When a question goes wrong, distinguish a concept gap from a misread term, ask a precise clarification question, then move from supported practice to a closed-book attempt.

These are suggested practice routes, not compulsory reading lists. After a useful example, close the guide, attempt a changed question and return later without hints. Use the route selector when a different difficulty appears.

Scope, course routes and official references

This page is a learning-guide index, not an official syllabus, examination paper or marking scheme. A guide’s presence does not make every term in it a compulsory PSLE requirement. Some guides use more precise language to help parents and tutors explain a distinction; keep the learner’s actual task, course level and school guidance in view.

For examination rules, use the SEAB PSLE formats examined in 2026, which lists Standard and Foundation subjects separately. For the curriculum, begin with MOE’s Primary school subjects and syllabuses. Check the appropriate examination year when using older practice papers. The learning prompts in this hub are eduKate teaching suggestions, not official marking formulas.

Parent and tutor teaching guide: one difficulty, one next step

Start with the child’s work, not the size of the library. Ask the learner to explain what they thought the question required. Listen before supplying the missing word or method. Choose the section matching the first difficulty you can actually identify.

Read one guide together when support is needed. Use one example to make the distinction visible, then close it. Ask the learner to explain the difference in their own words and attempt a changed example. Record whether the answer was independent, prompted or copied; those are different observations about readiness.

For a confusion such as trial versus measurement, ask what exactly was repeated. For a relationship-versus-cause error, ask which claim came from the data and which came from scientific knowledge. For a question–prediction–conclusion error, ask what was known when each statement was written. Match the prompt to the difficulty, then remove the prompt as the learner becomes able to do the task.

Do not make reading every guide the target. A more useful target is a learner who can say what the question asks, choose the relevant evidence, use the right concept, write a defensible answer and check it without being carried through every step. Return to the route selector whenever the next difficulty becomes clearer.

Follow a learning sequence

Changes in quantities: Begin with increase by and increase to, continue to different starting values, then rate and amount, and finish with answer checking.

How investigation evidence is organised: Begin with trials, measurements and specimens, continue to what a results-table row represents, then repeated trials or more specimens, and finish with evaluating the investigation method.

From relationships to defensible conclusions: Begin with relationship statements, continue to data patterns and mechanisms, then evidence of difference and cause, and finish with evidence-bounded conclusions.

From prediction to an independent return test: Begin with questions, predictions and conclusions, continue to predictions against actual results, then evidence-bounded conclusions, and finish with delayed independent retesting.

After each step, attempt a changed example independently. Return to the Science route selector when a different difficulty appears.

Reconnect the PSLE question to concepts, course and diagnosis

For connected concepts and worked practice, return to the Primary 6 Science Learning Hub. Use How PSLE Science Works to locate the existing Standard or Foundation route, or the Science Learning Library for a focused concept explanation.

When the next repair is unclear, use Use the Paper to Find the Failure. Then choose the matching guide above and attempt a changed Science question independently. This page remains the question-and-skill index.
