The PSLE Foundation Science syllabus assesses whether pupils understand basic scientific knowledge and can apply it using simple forms of scientific inquiry. The Foundation route has its own syllabus and examination format. This guide explains the revised 2026 paper, the role of the word list, the concepts and reasoning pupils should develop, and how parents can support Science learning without relying on memorised paragraphs alone.
SEAB’s Foundation Science syllabus for examination from 2026 states that the paper assesses attainment in Science as described in the 2023 Primary Science Syllabus. Pupils need to demonstrate knowledge and understanding of scientific facts, concepts and principles, apply them, make predictions and formulate hypotheses, interpret and analyse information, evaluate observations and methods, and communicate explanations with reasoning. The paper comprises two booklets and lasts 1 hour 15 minutes.
- Foundation Science is subject code 0039 in the 2026 PSLE format; Standard Science is 0009.
- The 2026 Foundation Science paper is 70 marks and lasts 1 hour 15 minutes.
- Booklet A has 20 multiple-choice questions, each worth 2 marks, for 40 marks.
- Booklet B has 9–11 short-response and structured questions worth 30 marks in total.
- Candidates answer all questions in both booklets.
- A word list is provided to reduce undue disadvantage from weakness in English, but SEAB states that the list is not exhaustive.
- The assessment includes knowledge with understanding and application of knowledge and scientific inquiry, not only recall of definitions.
1. What Foundation Science is designed to assess
Foundation Science is a subject-level route that focuses on pupils’ grasp of basic scientific knowledge while still requiring them to use that knowledge. It is not simply a test of memorising names and definitions. Pupils must understand what a scientific idea means, recognise relevant information in a question and use it to explain or predict an outcome. The 2026 syllabus explicitly includes application and scientific inquiry as assessment objectives.
The 2023 Primary Science Syllabus organises primary Science around broad themes and learning through scientific knowledge, practices and values. Pupils should be able to observe carefully, compare, classify, infer, predict, analyse information, evaluate evidence and communicate explanations. Foundation Science retains an emphasis on core knowledge but expects pupils to use the skills needed to make sense of a situation.
Parents should distinguish remembering a scientific fact from understanding how it works. A child may remember that plants require certain conditions, but still struggle when asked to interpret an investigation in which one condition changes. Another child may understand the concept but overlook a graph label. These are different issues. The first requires stronger conceptual connections; the second needs careful reading and evidence handling.
2. The revised 2026 Foundation Science paper
The 2026 examination consists of one written paper with two booklets. Booklet A contains 20 multiple-choice questions with three options; each question carries two marks, giving 40 marks. Booklet B contains 9–11 short-response and structured questions worth 30 marks. Candidates must answer all questions. The paper lasts 1 hour 15 minutes.
The paper is not divided into separate practical and theory examinations in the format set out in the 2026 subject information. Pupils may nevertheless need to reason about investigations, diagrams, tables, graphs and scientific situations. Scientific inquiry is assessed through the way candidates interpret information, make predictions, evaluate methods and communicate explanations. Parents should therefore avoid assuming that Science preparation means memorising only textbook paragraphs.
3. Why a word list is provided
SEAB states that a word list is provided during the Foundation Science examination so that candidates can demonstrate their scientific knowledge and understanding without being unduly disadvantaged by weakness in English. The list is not exhaustive. This provision recognises that Science understanding and English proficiency are related but distinct. A pupil may understand a scientific concept even when a particular technical word is difficult to retrieve.
The word list does not mean that pupils can ignore scientific vocabulary. They still need to understand the concept, recognise what the question is asking and communicate a relevant answer. A word list cannot replace understanding a process, interpreting a diagram or connecting cause and effect. Parents should teach the meaning of important terms and allow the child to practise using them in simple, accurate sentences.
Parents should also avoid telling a child that the word list contains every answer term. SEAB explicitly notes that it is not exhaustive. The pupil must know the underlying concept and should practise explaining it in their own words. When a word is unfamiliar, the child should learn to use the information in the question, diagrams and prior knowledge to work out what is being asked.
4. Knowledge with understanding
Knowledge with understanding means that pupils can demonstrate scientific facts, concepts and principles at the level taught. It includes knowing important terms, recognising the parts of a system, describing a process and understanding relationships. The child should not only repeat a definition but also identify when the concept is relevant and describe it in a way that matches the question.
The 2023 Primary Science Syllabus includes themes such as Diversity, Cycles, Systems, Interactions and Energy. These themes organise scientific understanding and help pupils connect ideas. For example, an organism can be understood through its characteristics and how it interacts with its environment. A cycle can be understood by tracing the stages and conditions. A system can be understood by identifying its parts and their functions.
The exact topics and depth should be checked against the current syllabus and the pupil’s school sequence. Parents should not assume that a generic Standard Science topical list is automatically the full Foundation syllabus. Ask the teacher which concepts have been taught, which are included in the child’s course and how the pupil is expected to explain them.
5. Scientific inquiry: the part parents should not overlook
The 2026 Foundation Science assessment objective includes scientific inquiry. SEAB lists making predictions and formulating hypotheses, interpreting and analysing information, evaluating observations, information and methods, and communicating explanations with reasoning. These skills help pupils investigate a question rather than simply recall a statement.
Observation and inference
An observation states what is seen or measured. An inference is an explanation drawn from observations and existing knowledge. A child should not confuse the two. ‘The water level decreased by a measured amount’ is an observation. ‘The water evaporated’ is an explanation that depends on the situation and evidence. Ask the pupil to separate what the data directly shows from what the data may mean.
Prediction and hypothesis
A prediction describes what may happen under stated conditions. A hypothesis is a proposed explanation that can be investigated. Children should learn to connect a prediction to the concept being tested. A statement such as ‘the plant will grow better’ is incomplete unless the child explains which condition is changing and why the expected outcome follows from the scientific idea.
Analysing and evaluating
Analysis involves identifying patterns, comparing results and interpreting what the information shows. Evaluation considers whether the evidence or method is suitable. Pupils may need to notice whether a comparison is fair, whether the same conditions were used or whether the data supports the conclusion. At Foundation level, these skills should be taught with clear, concrete examples and age-appropriate language.
6. Reading diagrams, tables and graphs
Science questions often contain visual information. Pupils should start with the title, labels, units, arrows and scale. They should identify which part of the visual is relevant to the question and compare the correct values or features. If the child rushes into an answer without reading the labels, a simple misunderstanding can affect the whole response.
Teach the pupil to describe what the data shows before explaining why it might happen. If a table compares two groups, identify the values in both groups. If a graph shows a change over time, notice the direction and any important differences. If a diagram shows a process, follow the arrows and identify what each part represents. This is better than memorising a single model answer and trying to fit it to every question.
After answering, ask what evidence supports the response. A good explanation should be connected to the diagram, table or information given. The child should avoid making claims that go beyond the evidence. This habit builds scientific accuracy and helps pupils become more careful thinkers.
7. Short-response and structured questions
Booklet B includes short-response and structured questions. Pupils need to answer the specific question and communicate a clear scientific relationship. A short answer may be enough when the question asks for a fact, while a structured explanation may require the pupil to connect a condition with an outcome. The child should read the command carefully and include the relevant detail.
For a question asking why, a pupil should explain a cause or relationship rather than merely naming an object. For a question asking what was observed, the response should describe the evidence rather than give an unsupported explanation. For a comparison, both relevant sides should be addressed. Parents can practise by asking the child to explain an idea in one or two complete sentences and then checking whether those sentences answer the actual question.
Do not encourage pupils to write a long paragraph for every question. Length does not guarantee correctness. A response should be complete enough to show the concept and concise enough to remain focused. The child should learn to use accurate terms and explain the link between them.
8. Foundation Science and Standard Science
Foundation Science and Standard Science are different subject levels with distinct subject codes and assessment formats. The Foundation route is based on the Primary Science syllabus as specified in its subject information, and the 2026 document explicitly refers to the 2023 Primary Science Syllabus. Parents should not apply an older Foundation Science PDF or a Standard Science paper format to the revised 2026 Foundation examination.
SEAB’s earlier Foundation Science subject information referred to the 2014 Primary Science Syllabus and a different paper structure. The current document for examination from 2026 now refers to the 2023 syllabus and specifies 20 multiple-choice questions and 9–11 short-response and structured questions. This is an important reason to check the version and year of the PDF before using it for preparation.
Discuss subject-level recommendations with the school. Ask which concepts the child understands, how the pupil applies scientific ideas, whether language comprehension is affecting responses and what additional support may help. Do not assume that one low Science score should automatically determine the subject level. Look for consistent learning evidence across schoolwork and time.
9. Foundation grades and secondary school posting
Foundation subjects are graded A, B or C for the PSLE. For calculation of the overall PSLE Score used for secondary school posting, Foundation grades are mapped to equivalent Standard Achievement Levels: A maps to AL 6, B to AL 7 and C to AL 8. Parents should read MOE’s current scoring explanation and the school’s guidance for the pupil’s cohort.
The scoring conversion is an administrative rule and should not be confused with the learning route. It does not mean that the Foundation and Standard syllabuses are identical. Parents should understand how the overall score is calculated and how school posting works, but should also consider the child’s readiness and well-being. A subject level should not be chosen purely because of a perceived prestige difference.
10. A practical preparation pathway
First, review the pupil’s science notes and recent work. Identify whether errors come from missing factual knowledge, misunderstanding a concept, misreading a diagram, confusing observation with inference or giving an incomplete explanation. Choose one or two recurring needs. This diagnosis is more useful than immediately assigning another large practice paper.
Second, rebuild the concept using a drawing, model, safe observation or simple example. Ask the pupil to explain the idea in their own words and then use the correct scientific term. If the child cannot explain the concept without the notes, return to the example and simplify it. Move to a new context only when the basic idea is more stable.
Third, practise applying the concept. Use a question with a diagram or table and ask the child to identify the relevant evidence. Change one detail and ask what might happen. Encourage the pupil to justify the answer. This helps the child learn to transfer knowledge rather than memorise one response.
Fourth, prepare for the examination format. Practise multiple-choice questions and short-response or structured questions. Build stamina for the 1 hour 15 minute paper gradually. After practice, discuss mistakes and revisit the concepts. Do not use repeated timed papers as a substitute for teaching.
11. Safe Science learning at home
Parents can encourage scientific curiosity through safe observations of plants, shadows, weather, materials, simple movement and everyday devices. Children can draw what they notice, compare two situations and ask questions. Do not conduct experiments involving heat, electricity, chemicals, sharp objects or unsafe materials without appropriate supervision and equipment. The aim is to develop observation and questioning, not recreate a laboratory at home.
Ask the child to record what happened before explaining why. If a prediction was made, return to it and discuss whether the evidence supports it. It is acceptable for a prediction to be wrong. Scientific learning involves checking ideas against observations and revising explanations when new evidence appears.
12. When to seek additional help
Additional support may be appropriate when a pupil cannot explain core concepts, repeatedly misinterprets data or finds it difficult to connect a scientific idea to a new situation. Parents should first speak with the school and identify the specific issue. A tutor should be able to explain how lessons align with the 2023 Primary Science Syllabus and the revised 2026 Foundation Science assessment.
Ask how the tutor identifies gaps, teaches scientific vocabulary, develops inquiry skills and reviews progress. Be wary of claims that a provider can predict exact PSLE questions or guarantee a particular grade. A responsible programme explains what it can teach and how it will help the pupil become more independent.
13. How eduKate’s learning approach can support Science
eduKate’s wider learning approach can help pupils connect a scientific concept to examples, organise the key vocabulary, identify evidence and explain relationships. A useful learning cycle is to understand the concept, look at a safe example, identify what changed or what is observed, explain the result and apply the idea in another context. This is supplementary learning support and does not replace the MOE syllabus or SEAB subject information.
For a child who struggles with written explanations, language and vocabulary can be taught alongside Science concepts. For a child who memorises facts without application, practise with unfamiliar but age-appropriate contexts. The objective is a pupil who can explain why an answer makes sense, not one who has simply copied more notes.
14. Questions parents should ask the teacher
- Can my child explain the key concepts in their own words?
- Does the pupil distinguish observations from inferences and predictions?
- Can the child read and interpret simple tables, diagrams and graphs?
- Are errors caused by knowledge gaps, reading, vocabulary or explanation?
- What is the school’s current Foundation Science topic sequence?
- Which 2026 SEAB assessment requirements should guide our practice?

For PSLE scoring, read MOE’s [PSLE scoring explanation](https://www.moe.gov.sg/microsites/psle-fsbb/psle/main.html). Do not use the older Foundation Science document for examination from 2017 as though it were the revised 2026 format.
The best Foundation Science preparation is a child who understands core ideas, reads scientific information carefully and uses evidence to explain an answer. Parents can support this by keeping learning practical, checking the correct syllabus year and choosing a realistic plan that builds independence.
14. The difference between knowing a fact and applying it
Foundation Science assesses knowledge with understanding and application of knowledge and scientific inquiry. This means a pupil should know a concept and recognise how it applies in a new situation. Memorising a sentence is useful only when the child understands what it means. A question may describe a different object or environment and ask the pupil to use the same scientific principle.
After teaching a concept, change one part of the example and ask the child what might happen. The pupil should identify which information has changed and connect the prediction to the scientific idea. Keep the new situation age-appropriate and within the syllabus. This method helps the child move from copying a model answer to using knowledge independently.
15. Fair testing and variables
Some questions describe an investigation and ask whether the comparison is fair. A pupil should identify what is changed, what is measured or observed and which conditions should remain the same. The purpose is to make a meaningful comparison. If several factors change at once, it becomes difficult to know which factor caused the result.
Use a simple example such as comparing how different materials absorb water. The material may be changed while the amount of water and the time allowed are kept consistent. The amount absorbed is then observed or measured. Ask the child to explain why keeping other conditions similar makes the comparison more useful.
Do not teach definitions alone. Ask pupils to identify the changed and observed factors in several different situations. The setting may change, but the reasoning is similar. A child who understands the relationship can apply it even when the investigation looks unfamiliar.
16. Formulating a hypothesis and making a prediction
A hypothesis proposes an explanation that can be investigated, while a prediction describes what may happen under specified conditions. Pupils should learn to connect the statement with the scientific concept involved. Avoid accepting vague answers that say only ‘it will change’ or ‘it will become bigger’. Ask what will change and why.
Parents can practise with safe observations. Before observing a plant over time, ask what the child expects to happen and what condition may influence it. Record the prediction, then observe and compare. If the outcome is different, discuss what the evidence suggests. The child learns that changing an explanation in response to evidence is part of scientific thinking.
17. Evaluating information and methods
Evaluating means considering whether an observation, piece of information or method is suitable. A pupil may need to notice that a measurement was not taken consistently or that the information does not support a conclusion. The child should not assume that every conclusion in a question is correct. Read the evidence and decide whether it supports the claim.
A useful question is: what else would we need to know? If the data compares two groups, were the relevant conditions similar? If the diagram gives only one observation, can it establish a general rule? At Foundation level, the reasoning should remain simple and clear, but pupils can still learn not to make claims beyond the available evidence.
18. Communicating explanations clearly
The child should learn to express a scientific explanation in a direct sentence or short sequence of sentences. Identify the relevant concept and explain how it connects to the situation. If the question asks for a reason, naming an object or process is not enough. If it asks what was observed, the response should describe the evidence rather than jump straight to an explanation.
Use a simple response routine: state the idea, refer to the condition or evidence and explain the outcome. For example, a pupil may need to compare two materials and say which one allowed more water through, then connect the result to the observed property. The exact scientific content depends on what has been taught. Keep the language precise without overloading the answer.
19. How to use the word list properly
The Foundation Science word list is a support during the examination, not a complete dictionary of every scientific term. SEAB says it is provided to reduce disadvantage caused by weakness in English, but it is not exhaustive. Pupils should still understand core ideas, recognise the information in a question and use relevant language where they can.
Practise learning terms through a concept map or short vocabulary record. Write the word, a child-friendly meaning, a diagram or example and a sentence that uses the word correctly. Revisit the terms after a few days. This helps the child retrieve meaning rather than memorise the appearance of a word.
20. Common answer errors and how to correct them
One common error is to write a memorised statement that does not answer the specific question. Another is to describe a diagram without explaining the relationship. Pupils may also confuse a prediction with an observation or identify a cause without referring to the evidence. Ask the child to read the question command and underline the part that must be answered.
A second error is giving too much unrelated information. The child may list several facts in the hope that one matches the expected answer. Teach the pupil to select the relevant concept and explain it. A concise, accurate response is more useful than a long answer that introduces contradictions.
A third error is misreading visual data. The pupil may overlook a scale, label or unit. Before answering, require the child to identify what each label represents. Then ask the pupil to point to the evidence that supports the answer. This habit helps separate understanding of Science from simple reading mistakes.
21. Build a Science concept notebook
A concept notebook should not become a second textbook. For each topic, include the main idea, important terms, a simple labelled diagram and one example of how the concept applies. Add a short question that requires the pupil to explain or predict something. The child should be able to use the notebook for revision and then close it and recall the main idea.
Organise concepts around connections rather than copying every note in order. A diagram can show a process, while a table can compare features. Ask the pupil to explain the arrows, labels and relationships. If the child cannot explain the visual, simplify it. A colourful page is not evidence of understanding unless the pupil can use its information.
22. Safe home activities that support inquiry
Simple activities can develop observation without creating a laboratory at home. Children can compare shadows at different times, observe how a plant changes or notice how materials behave in water. Use ordinary, safe materials and adult supervision where appropriate. Avoid experiments involving heat, chemicals, electricity or sharp objects unless they are part of a properly supervised school activity.
Ask the pupil to record what was observed, not just what was expected. Then discuss possible explanations and what further information might be needed. If a child changes an opinion after seeing evidence, praise the careful thinking. This helps pupils see that science is a way to investigate questions, not just a set of facts to remember.
23. A six-week Foundation Science improvement cycle
Week one: review recent work and identify recurring weaknesses in knowledge, inquiry or written explanation. Week two: rebuild one important concept with a diagram or safe example. Week three: practise explaining the concept and using the correct vocabulary. Week four: interpret a new table, diagram or investigation based on the same idea. Week five: complete a short examination-style section. Week six: review errors and check whether the pupil can now apply the idea independently.
If the child needs more than one week to understand a concept, extend that stage. The cycle should follow the school’s topic sequence and the pupil’s readiness. A rigid schedule is less important than making sure that the child understands before moving on. Keep the workload balanced across other subjects and rest.
24. How to decide whether additional Science support is needed
Speak with the teacher if the child cannot explain key concepts, repeatedly misreads visual information or gives answers that do not connect to the question. Ask whether the difficulty is scientific understanding, vocabulary, reading or response construction. A focused explanation from the teacher may be enough; in other situations, additional guided practice can help.
When evaluating a tutor, ask how the lessons align with the 2023 Primary Science Syllabus and the revised Foundation Science paper for examination from 2026. Ask whether the child will practise inquiry skills, how word-list use is explained and how progress is checked. Avoid promises to predict examination questions or guarantee a grade.
25. How to measure meaningful progress
Progress should be measured by what the child can do without prompting. Can the pupil explain the main idea, identify the relevant evidence, make a reasoned prediction and communicate an answer? Can the child apply the idea to a slightly different context? These signs are more useful than the number of pages of notes copied.
Use a small set of questions again after a few weeks, but change the context where possible. Compare the child’s explanation and reasoning. If the pupil is still making the same error, revisit the teaching method. The aim is not to finish a checklist but to build the ability to use Science knowledge with increasing confidence.
