eduKateSG · PSLE FOUNDATION SCIENCE · 0039 · 2026 REVISED FORMAT · PHASE 4
Foundation Science Is a Focused Science Route. The Goal Is Still to Understand the World Correctly.
PSLE Foundation Science has its own syllabus requirement, its own subject code and its own revised 2026 paper. It should not be taught as Standard Science with random chapters crossed out or as a vocabulary exercise for weaker students.
The learner still has to understand scientific facts and principles, apply them to unfamiliar information, interpret diagrams and tables, make predictions, analyse observations and communicate explanations with reasoning. The route is more focused, but the core scientific habit remains the same: a claim should follow from a model and the model should answer to evidence.
The 2026 Foundation Science paper is also designed to reduce unnecessary language barriers. SEAB provides a word list during the examination so a candidate can demonstrate scientific understanding without being unduly disadvantaged by weakness in English. That does not remove the need for clear language. It changes where the support is placed.
This new Phase 4 page gives Foundation Science a dedicated national owner inside the existing eduKateSG PSLE Science architecture.
What This Page Owns
This is the canonical eduKateSG page for PSLE Foundation Science 0039 under the revised 2026 format. It owns the Foundation paper structure, focused syllabus route, word-list support, MCQ/short-response/structured execution, scientific inquiry and final-year repair.
It does not duplicate PSLE Standard Science 0009, which is a 100-mark full Standard paper. It also remains distinct from Primary 6 Science, which owns the year-level learning progression.
The Official 2026 Foundation Science 0039 Format
SEAB lists Foundation Science 0039 as revised for examination from 2026. It is one written paper comprising two booklets.
| Booklet | Item type | Questions | Marks |
|---|---|---|---|
| A | Multiple-choice, three options | 20 | 40 |
| B | Short response and structured | 9–11 | 30 |
| Total | All questions compulsory | 29–31 | 70 |
Each Booklet A MCQ carries 2 marks. Booklet B contains short-response and structured work carrying 2–4 marks per question. About 10 marks in Booklet B may come from short-response formats such as fill-in-the-blanks or matching. The total duration is 1 hour 15 minutes.
A word list is provided during the examination. SEAB notes that the list is not exhaustive.

Foundation Science Still Assesses Knowledge, Application and Inquiry
The Foundation syllabus uses the same broad assessment-objective language as Science 0009.
Knowledge with Understanding
The candidate must know and understand scientific facts, concepts and principles in the Foundation syllabus.
Application of Knowledge and Scientific Inquiry
The candidate must apply Science, make predictions/hypotheses, interpret and analyse information, evaluate observations/information/methods, and communicate explanations with reasoning. These skills may be assessed through words, diagrams, tables and graphs.
This matters because “Foundation” should not be translated into “memorise the simple answer”. The student still needs a model strong enough to work when the question looks different.
The route is narrower. The scientific reasoning should still be real.
What Is Different in the Foundation Syllabus?
The current Primary Science syllabus marks selected content as not required for Foundation Science. In the P6 overview, Energy Conversion and elastic spring force are Standard-only requirements.
This is important for study efficiency. A Foundation candidate should not carry unnecessary Standard-only content simply because an old worksheet, sibling’s notes or online resource includes it.
At the same time, Foundation Science still draws on Primary Science across the five themes—Diversity, Cycles, Systems, Interactions and Energy—within its required scope. The child still needs earlier concepts from P3, P4 and P5 to make P6 questions work.

The correct preparation principle is therefore:
Remove what is not required, but do not break the relationships among what remains.
The Foundation Science Learning Spine
A focused syllabus is most powerful when the child can reuse a small number of operations across many topics.
- Classify: use relevant characteristics to group living things, non-living things or materials.
- Track a cycle: identify stages or state changes and how the sequence continues.
- Follow a system: connect a part to its function and the consequence for the whole system.
- Identify an interaction: state what acts on what and what changes.
- Use evidence: connect a table, graph, observation or measurement to a conclusion.
- Explain causally: give the relevant reason and trace it to the outcome.
- Predict: apply the same model after one condition changes.
- Check: make sure the answer matches the diagram, data and command word.
These operations are the backbeats. The topic wrapper changes; the operation remains.
Booklet A: Three Options Still Require Real Discrimination
Foundation Science Booklet A contains 20 MCQs with three options each. Fewer options do not mean guessing is a good strategy. A weak concept can still make two choices look equally plausible.
We train students to ask:
- What topic or process is this really testing?
- Which fact or relationship definitely applies?
- Which option contradicts that relationship?
- Does the diagram or data rule out another option?
- Does the final choice answer the exact question?
When reviewing a wrong MCQ, the child should explain why the chosen option was wrong. This turns the distractor into a diagnostic.
Because Booklet A contributes 40 of 70 marks, stable MCQ performance matters enormously. But the repair for unstable MCQ is conceptual discrimination, not simply “read more carefully”.
Booklet B: Short Response and Structured Questions Need Different Output
Booklet B mixes short-response items and structured questions. The child must recognise which response is required.
Short response
Fill-in-the-blank, matching or short identification items reward accurate retrieval and vocabulary. The provided word list can support access, but the student still needs to know which word fits the scientific relationship.
Structured response
These questions require more than naming. The child may need to interpret a diagram, compare results, use evidence or explain a cause-and-effect relationship.
We teach a compact structure:
What changed / what is shown → relevant Science idea → consequence or conclusion.
The sentence can be simple. Simplicity is valuable when it is scientifically complete.
The Word List Is Support, Not the Science Model
The provision of a word list is an important access design. It acknowledges that a child can understand Science yet struggle to retrieve or spell a specific English term under examination conditions.
But the word list cannot decide:
- which process the question is testing;
- which variable changed;
- which organ or component is relevant;
- what the graph trend means;
- why a result occurred;
- which evidence supports a conclusion.
Therefore Foundation Science tuition should not become a vocabulary-only programme. We use language support to reduce friction while keeping the scientific reasoning intact.
A useful practice is to let the child explain aloud in their clearest available language first, then help convert the explanation into the concise English needed for the paper. This separates “I do not understand the Science” from “I cannot yet express the Science.”
Foundation Science Should Be Taught for Transfer, Not Recognition
A child may learn that “roots absorb water” and answer the familiar sentence correctly. Transfer begins when the question shows a plant with damaged roots, changes the amount of water available, or gives a graph rather than a labelled diagram.
The same principle applies across the route:
- materials appear in a new object;
- life-cycle stages appear in a different organism;
- matter changes appear in a real-world water context;
- body-system functions appear inside exercise or health scenarios;
- circuits are redrawn;
- friction or gravity appears in unfamiliar motion;
- photosynthesis appears inside an investigation;
- environmental interactions appear in a new food relationship.
We change the wrapper while protecting the concept. If understanding survives, the child is becoming less dependent on worksheet recognition.
Experiments and Data: Keep the Question Small Enough to See
Foundation candidates are still assessed on scientific inquiry. Complex diagrams can create unnecessary load if the child does not know what to extract.
We reduce the experiment to four first questions:
- What did they change?
- What did they measure or observe?
- What stayed the same?
- What did the result show?
Only then do we add evaluation or prediction.
For a graph, first read the axes. For a table, locate the correct comparison. For a diagram, name what the arrows mean. These small routines reduce working-memory load and make the evidence visible.
The Foundation route benefits enormously from good representation teaching because a child can understand a concept orally yet become lost when it is compressed into a graph or symbolic diagram.
The Foundation Science Error Map
| Visible problem | Likely hidden cause | Repair |
|---|---|---|
| Needs answer options to remember | Recognition stronger than retrieval | Short closed-book recall with visual support faded gradually |
| Knows orally but cannot write | Language output bottleneck | Explain aloud → select key Science relationship → write one clear sentence |
| MCQ guesses between two choices | Scientific distinction is fuzzy | Explain why each option is possible/impossible |
| Graph question causes blanking | Representation is not decoded | Axes → pattern → Science meaning |
| Experiment answer is random | Variable roles are invisible | Change → measure → same → result |
| Structured answer repeats question | Causal link is missing | Relevant fact/process → consequence |
| Standard-only topics consume time | Revision route is not syllabus-specific | Remove non-required content and protect Foundation core |
| Timed paper collapses | Reading/output pace is unstable | Timed short sets before full-paper simulation |
A 75-Minute Paper Needs a Different Timing Habit
Foundation Science gives the student 1 hour 15 minutes for the complete paper. That is a shorter operating window than Standard Science.
The child should therefore practise switching efficiently from Booklet A recognition to Booklet B generation. A difficult MCQ should not consume the time required for several short-response or structured marks.
Useful habits include:
- answer clear MCQs decisively and mark uncertain ones for return;
- use the provided word list when it reduces language friction, not as a substitute for reading the question;
- write short responses directly;
- for structured questions, identify the changed condition before writing;
- leave enough time to check unanswered items and obvious contradictions;
- do not copy long sentences when a precise short answer earns the mark.
Timing practice should start with short sections. Once the child can execute the underlying reasoning reliably, full 75-minute simulations become useful.
A Typical Foundation Science Tutorial
- 10 minutes — Retrieval: short, confidence-building recall across required P3–P6 content.
- 15 minutes — Core concept repair: use real objects, diagrams or simple models to restore the relationship.
- 15 minutes — MCQ discrimination: three-option questions with reasons for rejection.
- 15 minutes — Short/structured response: oral explanation first where useful, then concise writing.
- 10 minutes — Experiment/data: change, measure, control and conclude.
- 10 minutes — Timed transfer and error closure: new wrapper plus the one distinction to retrieve next lesson.
For a child who is already anxious about Science, the lesson should not begin with repeated proof of failure. We begin at the earliest concept the learner can repair successfully, then widen the operating range.
The small-group setting allows support to fade at different rates. One student may need the diagram labelled initially; another may need only a question prompt. The destination is the same: increasing independence.
What Progress Looks Like in Foundation Science
- the child knows which syllabus route they are preparing for;
- Standard-only content no longer consumes revision time;
- basic P3–P6 concepts can be retrieved without answer options;
- three-option MCQs are solved by scientific distinction rather than guessing;
- the word list is used as language support rather than a clue bank;
- short-response items become faster and more precise;
- structured answers connect a scientific reason to an outcome;
- graphs and tables are decoded with a stable routine;
- experiment questions are reduced to change/measure/control/result;
- the child can explain an answer orally and convert it into concise written Science;
- timed practice becomes less volatile;
- the learner begins to approach unfamiliar questions as solvable rather than alien.
Frequently Asked Questions
What is the 2026 Foundation Science code?
Foundation Science is subject code 0039 in the 2026 PSLE format list.
How many marks is the 2026 paper?
70 marks in total: 40 marks from Booklet A and 30 marks from Booklet B.
How many MCQs are there?
20 MCQs with three options each, carrying 2 marks per question.
What is in Booklet B?
There are 9–11 short-response and structured questions worth 30 marks in total. Short-response formats such as filling blanks or matching account for about 10 marks.
Is a word list really provided?
Yes. SEAB states that a word list is provided during the Foundation Science examination to reduce disadvantage from English-language weakness. The list is not exhaustive.
Is Energy Conversion required for Foundation Science?
The current MOE Primary Science overview marks Energy Conversion as not required for Foundation Science.
Is elastic spring force required?
The current MOE overview marks elastic spring force as a Standard-only requirement; Foundation students still learn the required force content in their own route.
Should a Foundation student use Standard Science papers?
Selected shared-content questions can be useful, but the main preparation should match the Foundation syllabus and 0039 format. Using full Standard papers indiscriminately introduces unnecessary content and a different mark/time architecture.

How PSLE Foundation Science Works
Foundation Science works best when the route is respected. Remove unnecessary content. Reduce language friction. Make representations clear. Keep the evidence chain visible. Give the child enough successful retrieval to rebuild confidence, then introduce unfamiliar contexts gradually.
The objective is not to imitate a Standard Science student. It is to become a strong Foundation Science student who can use the required Science independently under the actual 0039 paper conditions.
A focused syllabus is powerful when every remaining idea is taught to work.
