Did you know that the 2027 G1 Science examination can include videos, animations, matching tasks and drag-and-drop answers? Its electronic format is distinctive, but Science still means asking how we know something, explaining what was observed and recognising the limits of evidence. This Bukit Timah guide uses the official K123 syllabus so that families can build the right knowledge rather than guess next year’s digital screen.
The quick answer: K123 uses a 75-minute electronic Paper 1 of 50 marks and 50% and a one-hour written Paper 2 of 50 marks and 50%. Electronic Paper 1 includes thirty MCQs plus selected-response and video or interactive questions. The written paper includes an 8–12-mark data-response task. There is no separate national hands-on practical paper, though experimental skills remain important.
Updated 25 October 2026. Featured media shows students in an ordinary school setting, not an actual national examination. All scenario examples are fictional, and practical skills must be developed in authorised school conditions.
Jump to: 1. What G1 Science K123 means for the 2027 SEC Did you know that the first Singapore-Cambridge Secondary Education Certificate includes a G1 Science subject with an electronic examination? The syllabus is K123 and its previous reference code was 5148. It sits within the new common certification system but retains a specific G1 curriculum and assessment. It is not interchangeable with Combined Science at G2 or G3 or with a pure G3 Science subject. · 2. The 50/50 balance and paper durations K123 has two compulsory papers. Paper 1 is a 75-minute electronic examination worth 50 raw marks and 50% of the subject. Paper 2 is a one-hour written paper, also 50 marks and 50%. All questions in both papers are compulsory. This is the central planning fact for parents comparing practice resources. · 3. Paper 1 Section A: thirty MCQs plus selected responses Section A carries 40 of the e-exam’s 50 marks. Thirty are from compulsory multiple-choice questions, and another ten come from two to five selected-response tasks. The syllabus explicitly lists matching, checkbox, drag-and-drop and fill-in-the-blank among possible methods. Reading the instruction carefully is therefore as important as recognising an answer. · 4. Paper 1 Section B: video and animation questions Section B contributes ten marks through two or three selected-response, short-answer or structured tasks that may use video, animation or interactive stimuli. The visual can show change across time or a relationship that a static picture describes less vividly. Students still need to identify the variable, evidence and suitable syllabus principle. · 5. The one-hour written Paper 2 and data response Paper 2 is a compulsory written examination with short-answer and structured questions worth 50 marks. One question carries 8–12 marks and asks candidates to use supplied data or observations to interpret, evaluate or solve a problem. Some contexts may be unfamiliar, while the concepts required still come from the prescribed syllabus. · 6. The three themes should be revised together Machines Around Us (II) includes energy, electricity, waves and effects of force. Food Matters covers food sources, food chemistry and food safety. Our Body and Health (II) includes staying healthy, digestion, breathing and blood circulation. The themes focus on practical science knowledge but are not three unrelated sets of definitions. · 7. Energy conversions and the principle of conservation An appliance can transform stored chemical energy into electrical, kinetic, light, thermal or sound energy. The useful output varies with the device. Some transfers are not useful for its intended purpose, but energy is conserved. Saying that unwanted energy simply vanishes would contradict the central principle. · 8. Power, time, energy and the role of units Power is a rate of transferring energy. If an imagined device transfers 1,200 joules in sixty seconds, its average power over that interval is 20 watts. The number alone is insufficient; the unit tells the reader whether the result describes power or an amount of energy. · 9. Series, parallel circuits and safe electrical learning The Electricity topic covers series and parallel arrangements and relevant electrical power or energy relationships. Two drawings may contain the same lamps but connect them differently. Students must trace the branches and understand which components share a pathway rather than assume every circuit works alike. · 10. Waves and the interpretation of moving patterns Wave representations may show a pattern across distance or changes over time. A student should read the horizontal axis before deciding whether a visible separation represents a period or a wavelength. Similar-looking drawings can encode different quantities when their labels differ. · 11. How forces change movement or shape Forces can affect an object’s speed, direction or shape, depending on the other forces and conditions involved. A student who sees an object stop should not assume that all forces instantly disappear or that an energy store simply ceases to exist. Motion questions require attention to the actual observed change. · 12. Food sources and the journey to the consumer Food Matters asks learners to consider sources of food and how science supports practical food decisions. Food supply is connected to production, handling, storage and consumption. A familiar meal is therefore an invitation to ask useful questions about the underlying processes rather than a reason to memorise restaurant names. · 13. Food chemistry and changes in preparation Food Chemistry considers how components and preparation conditions can affect food properties. The same ingredient can behave differently under different processing conditions. Students should distinguish a visible observation from a proposed chemical explanation, and check whether enough information is supplied for that explanation. · 14. Food safety: cause, consequence and prevention Food safety is not a test of reciting warnings without understanding them. The syllabus expects knowledge applicable to practical situations. Students can learn to identify a relevant risk, explain why it matters and describe a suitable response under the scenario’s conditions. · 15. Digestion: how the system supports the body The Our Body and Health section includes digestion and the functions of relevant organs. Students need to recognise how a part of the body contributes to the movement and processing of food, not simply copy labels from a diagram. The explanatory link matters. · 16. Breathing and circulation work together Breathing brings air into and out of the respiratory system; circulation transports materials through the body. These activities support each other but have different roles. Students should first explain each process and then identify the connection relevant to the particular question. · 17. Staying healthy and understanding evidence Science can support informed choices about wellbeing while remaining separate from individual healthcare decisions. When students read a chart about a health-related behaviour, they should ask what was measured, who was included and which conclusion actually follows. · 18. Observation is different from inference An observation reports what was seen or measured. An inference uses a concept to suggest an explanation. When a video shows a change, students may be tempted to jump straight to a familiar conclusion. Strong Science separates those stages and checks which information supports the interpretation. · 19. Paper 2 data response: patterns are not proof of cause In the written paper, the eight-to-twelve-mark data-response question tests how students interpret and use information. Some datasets present clear trends, others may include unusual observations or limitations. The student should identify units, sample size and variables before calculating. · 20. Experimental skills remain important without Paper 3 SEAB’s syllabus lists selecting techniques, making and recording observations, handling experimental information, evaluating results and suggesting improvements. It encourages appropriate practical activities even without a separate national hands-on Paper 3. Examination questions can still refer to apparatus, safety and data. · 21. Scientific honesty when a result is unexpected A surprising reading should be recorded and assessed, not silently changed to match the expected result. Science involves testing ideas, and a discrepancy can reveal an unconsidered condition, instrument limitation or mistaken prediction. It is information to investigate responsibly. · 22. Familiarity with electronic controls The e-exam may use matching, checkbox selection, dragging and other response methods. These can look easy to a student familiar with digital games, but the formal task still demands scientific understanding and reading accuracy. Multiple selections and specific interaction instructions require attention. · 23. A workable weekly revision rotation A family might use Monday for Machines Around Us, Tuesday for Food Matters, Wednesday for Our Body and Health, Thursday for interpreting a table or graph, and Friday for legitimate e-exam practice. This is illustrative rather than an official five-day school timetable. · 24. Parent checklist for the 2027 SEC Confirm the K123 registration, the two paper durations and the real school plan for electronic familiarisation. Find out which topics the pupil understands and where the teacher sees recurring difficulties. Avoid buying expensive resources simply because they are labelled ‘new SEC’ without matching the syllabus. · Connected 2027 articles
1. What G1 Science K123 means for the 2027 SEC Did you know that the first Singapore-Cambridge Secondary Education Certificate includes a G1 Science subject with an electronic examination? The syllabus is K123 and its previous reference code was 5148. It sits within the new common certification system but retains a specific G1 curriculum and assessment. It is not interchangeable with Combined Science at G2 or G3 or with a pure G3 Science subject.
The official school-candidate directory identifies the level and code. A student may have entered secondary school through a particular Posting Group while learning individual subjects at levels appropriate to their progress. A parent should confirm the actual K123 entry with the school instead of assuming every pupil from the same form class faces identical examination requirements.
The subject uses three familiar themes: Machines Around Us (II), Food Matters, and Our Body and Health (II). That practical structure is valuable for Bukit Timah pupils, who encounter transport, household technology, groceries and public green spaces daily. Yet noticing a phenomenon is only the start of science. Pupils must describe observations, apply concepts and explain why the evidence supports a claim.
2. The 50/50 balance and paper durations K123 has two compulsory papers. Paper 1 is a 75-minute electronic examination worth 50 raw marks and 50% of the subject. Paper 2 is a one-hour written paper, also 50 marks and 50%. All questions in both papers are compulsory. This is the central planning fact for parents comparing practice resources.
The first paper presents some tasks through computers and varied interactive formats. The second requires short-answer or structured responses, including a substantial data-based question. A child needs familiarity with legitimate e-exam controls and the ability to express scientific reasoning in writing. One skill does not automatically compensate for difficulty with the other.
Do not copy the separate practical assessment structure of pure G3 Physics, Chemistry or Biology into a G1 revision plan. K123 has no separately weighted laboratory paper. Experimental knowledge and safe investigation are still important and can be tested through its two assessment papers. Two exams does not mean science practical work is unnecessary.
3. Paper 1 Section A: thirty MCQs plus selected responses Section A carries 40 of the e-exam’s 50 marks. Thirty are from compulsory multiple-choice questions, and another ten come from two to five selected-response tasks. The syllabus explicitly lists matching, checkbox, drag-and-drop and fill-in-the-blank among possible methods. Reading the instruction carefully is therefore as important as recognising an answer.
Imagine a fictional screen that asks which device converts electrical energy into light. A student must first understand the energy transfer; quick clicking will not supply the underlying explanation. A multi-select question is particularly risky if the pupil assumes there is always one correct option. Official school practice can teach how the interface signals its requirements.
At home, practise the concepts separately from the controls. Give a student a simple paper matching task linking physical quantities with units, or science observations with relevant causes, and ask for an explanation. Then use authorised SEAB familiarisation for the digital response technique. This distinguishes content misunderstanding from a user-interface problem.
4. Paper 1 Section B: video and animation questions Section B contributes ten marks through two or three selected-response, short-answer or structured tasks that may use video, animation or interactive stimuli. The visual can show change across time or a relationship that a static picture describes less vividly. Students still need to identify the variable, evidence and suitable syllabus principle.
Suppose an invented animation depicts a fan slowing after an unspecified change. The observation is that the motion became slower. The cause cannot always be determined without seeing the circuit, load or other details. A candidate who immediately says that energy disappeared would be making an unsupported claim inconsistent with the conservation principle.
A useful routine is to observe once for the overall change, read the question, focus on the relevant feature and decide which scientific idea is required. There is no need to guess the actual 2027 examination video. SEAB’s document defines the types of stimuli, not the confidential content that will appear during the sitting.
5. The one-hour written Paper 2 and data response Paper 2 is a compulsory written examination with short-answer and structured questions worth 50 marks. One question carries 8–12 marks and asks candidates to use supplied data or observations to interpret, evaluate or solve a problem. Some contexts may be unfamiliar, while the concepts required still come from the prescribed syllabus.
A fictional table containing times of two, four and six minutes and recorded quantities of three, six and nine units shows a pattern across the measured points. It does not, on its own, explain the process or establish that the relationship will continue forever. A reasoned answer distinguishes what the data show from a possible explanation.
Teach pupils to read titles, units and axes before calculating. Then ask which observation supports the answer, what mechanism is applicable and what limitation affects certainty. Writing more words is not necessarily better than one precise explanation linked to the actual measurements. This approach also supports learning in Geography and Mathematics.
6. The three themes should be revised together Machines Around Us (II) includes energy, electricity, waves and effects of force. Food Matters covers food sources, food chemistry and food safety. Our Body and Health (II) includes staying healthy, digestion, breathing and blood circulation. The themes focus on practical science knowledge but are not three unrelated sets of definitions.
Energy transformations can be illustrated by both appliances and the body’s use of nutrients. The movement of substances is relevant to electrical and biological systems, though the processes are different. Students who understand the limits of an analogy will be better able to apply ideas accurately rather than assume every transfer follows the same mechanism.
A family revision plan might rotate across these sections each week and include a separate recurring exercise for interpreting charts, diagrams and experiments. The student should keep a small list of unresolved misconceptions. A child who knows each topic title but cannot explain a simple cause-and-effect relationship needs concept teaching, not another word list.
7. Energy conversions and the principle of conservation An appliance can transform stored chemical energy into electrical, kinetic, light, thermal or sound energy. The useful output varies with the device. Some transfers are not useful for its intended purpose, but energy is conserved. Saying that unwanted energy simply vanishes would contradict the central principle.
For a fictional battery-powered lamp, chemical energy eventually contributes to light and thermal transfers. The lamp does not convert every unit of stored energy into useful light. A strong pupil can describe the relevant energy pathway using the information given without inventing extra mechanisms not stated in the scenario.
Ask a teenager to explain the energy flow in a school-approved diagram, then identify which information would be needed to compare two devices. A household device need not be opened or modified to practise the explanation. Observation, correct terms and scientific reasoning are enough for a safe home discussion.
8. Power, time, energy and the role of units Power is a rate of transferring energy. If an imagined device transfers 1,200 joules in sixty seconds, its average power over that interval is 20 watts. The number alone is insufficient; the unit tells the reader whether the result describes power or an amount of energy.
When interpreting a household bill, a pupil should not assume that the appliance with the highest rated power always uses the most total energy. Running time and other conditions matter. The syllabus allows students to reason about energy use without obtaining private family account details or using dangerous apparatus.
Make unit-checking automatic. Before a calculation, identify the units in the question and the quantity the examiner requests. Afterward, ask whether the value seems plausible for the scenario. A calculator that prints a number cannot know whether the pupil has confused seconds with minutes or joules with watts.
9. Series, parallel circuits and safe electrical learning The Electricity topic covers series and parallel arrangements and relevant electrical power or energy relationships. Two drawings may contain the same lamps but connect them differently. Students must trace the branches and understand which components share a pathway rather than assume every circuit works alike.
A fictional worksheet could show two lamps and a switch. A pupil can inspect which part of the circuit is controlled by that switch and explain the observation expected under the defined conditions. That is safe diagram reasoning. It is different from performing real electrical wiring.
Practical electricity work requires trained school supervision and approved equipment. Parents should not ask a child to open appliances, bypass a fuse or experiment with household sockets. This guide provides no home circuit-building instructions; safety is part of becoming scientifically competent.
10. Waves and the interpretation of moving patterns Wave representations may show a pattern across distance or changes over time. A student should read the horizontal axis before deciding whether a visible separation represents a period or a wavelength. Similar-looking drawings can encode different quantities when their labels differ.
An animated wave can make movement clearer, but it may also tempt learners to imagine that every particle travels from one end of the displayed picture to the other. A model should be interpreted according to what the syllabus and scenario say about the disturbance and the medium.
Practise describing a labelled diagram in words. What repeats? Which variable is changing? Which feature can actually be calculated from the information? A careful reader learns to resist dramatic visual impressions when the axes or assumptions do not support them.
11. How forces change movement or shape Forces can affect an object’s speed, direction or shape, depending on the other forces and conditions involved. A student who sees an object stop should not assume that all forces instantly disappear or that an energy store simply ceases to exist. Motion questions require attention to the actual observed change.
Imagine a fictional trolley moving on a level surface and gradually slowing. The pupil can discuss the role of opposing effects within the model taught, while recognising that the question may omit particular environmental details. Explaining the mechanism is more useful than saying the trolley ‘lost its force’.
Printed sketches and simple physical quantities provide safe practice. There is no educational need to create risky moving machines at home. A teacher can supervise appropriate hands-on demonstrations and help students compare observations with the scientific explanation.
12. Food sources and the journey to the consumer Food Matters asks learners to consider sources of food and how science supports practical food decisions. Food supply is connected to production, handling, storage and consumption. A familiar meal is therefore an invitation to ask useful questions about the underlying processes rather than a reason to memorise restaurant names.
An imagined comparison might show two food products with different storage requirements and dates. Students should explain what information is relevant to the particular question, not declare one choice safer solely because of its price, popularity or attractive packaging. Clear observations matter.
Families can use fictional labels or school-approved information for this kind of reasoning. They should not use a child’s Science homework as a substitute for actual food-safety regulations, inspection data or qualified personal nutrition advice.
13. Food chemistry and changes in preparation Food Chemistry considers how components and preparation conditions can affect food properties. The same ingredient can behave differently under different processing conditions. Students should distinguish a visible observation from a proposed chemical explanation, and check whether enough information is supplied for that explanation.
A hypothetical table comparing two prepared samples might record firmness or appearance. The pupil could identify the difference but would need relevant experimental details to conclude why it arose. Assuming that every texture change has one universal cause is not sound Science.
Food-related practical activities at school follow equipment, hygiene and safety rules. Parents need not reproduce them using heat or experimental reagents at home. Interpretation of legitimate recorded data can teach the reasoning skill safely.
14. Food safety: cause, consequence and prevention Food safety is not a test of reciting warnings without understanding them. The syllabus expects knowledge applicable to practical situations. Students can learn to identify a relevant risk, explain why it matters and describe a suitable response under the scenario’s conditions.
An illustrative question might describe a hypothetical storage procedure, with information about time and temperature. The pupil should analyse exactly the data given before choosing an explanation. Avoid claiming that a real local outlet has violated a rule simply because the scenario resembles its food category.
Respectful science communication uses appropriately limited claims. If the exam does not provide enough evidence for an absolute statement, the answer should not invent certainty. This habit also helps students evaluate sensational claims circulated online.
15. Digestion: how the system supports the body The Our Body and Health section includes digestion and the functions of relevant organs. Students need to recognise how a part of the body contributes to the movement and processing of food, not simply copy labels from a diagram. The explanatory link matters.
A teacher-provided drawing might show an organ and ask how its structure contributes to a specific function. A pupil who can answer in a clear causal sentence demonstrates understanding. A child who only repeats ‘for digestion’ may not have addressed the particular process the question asks about.
Use authorised educational diagrams at home and let the student describe what happens in their own words. Avoid drawing conclusions about an individual family member’s symptoms or designing personal treatments from school material.
16. Breathing and circulation work together Breathing brings air into and out of the respiratory system; circulation transports materials through the body. These activities support each other but have different roles. Students should first explain each process and then identify the connection relevant to the particular question.
Imagine a fictional question describing increased activity and changes to breathing rate. The explanation should use appropriate biological principles at G1 level, without diagnosing an individual or assuming one measurement represents a disease. General classroom knowledge is not personal clinical advice.
A labelled diagram plus a short explanation is often a useful revision tool. Ask which route a substance follows and why a structure is suitable. The pupil’s answer should be grounded in the diagram and taught concepts.
17. Staying healthy and understanding evidence Science can support informed choices about wellbeing while remaining separate from individual healthcare decisions. When students read a chart about a health-related behaviour, they should ask what was measured, who was included and which conclusion actually follows.
A fictional comparison of two small groups may show different behaviour frequencies. This does not prove that the behaviour caused every difference in outcomes, because other variables could matter. Scientific reasoning includes recognising the limits of an observational comparison.
Parents can reinforce careful language by asking ‘What does this show?’ and ‘What else would we need to know?’ This encourages healthy scepticism without teaching children to ignore trustworthy health information.
18. Observation is different from inference An observation reports what was seen or measured. An inference uses a concept to suggest an explanation. When a video shows a change, students may be tempted to jump straight to a familiar conclusion. Strong Science separates those stages and checks which information supports the interpretation.
Imagine an animation of a lamp changing brightness after an unspecified alteration. The change itself is visible, but the exact electrical cause may depend on connections and components not displayed. An accurate pupil will not claim to know details hidden by the presentation.
A simple classroom sheet with columns for observation, inference and missing information makes the distinction visible. Pupils can apply this to food, machines and body-system contexts without doing risky practical work.
19. Paper 2 data response: patterns are not proof of cause In the written paper, the eight-to-twelve-mark data-response question tests how students interpret and use information. Some datasets present clear trends, others may include unusual observations or limitations. The student should identify units, sample size and variables before calculating.
Suppose fictional readings at two, four and six minutes are three, six and nine arbitrary units. These three observations suggest a pattern across the measured range. They do not automatically establish what will happen months later or why the pattern occurred. Responsible answers avoid exaggeration.
Practise one question about what can be concluded and another about what cannot. The second is often more revealing. It helps students recognise that an explanation can be scientifically thoughtful without pretending to know everything.
20. Experimental skills remain important without Paper 3 SEAB’s syllabus lists selecting techniques, making and recording observations, handling experimental information, evaluating results and suggesting improvements. It encourages appropriate practical activities even without a separate national hands-on Paper 3. Examination questions can still refer to apparatus, safety and data.
A student who suggests ‘repeat the test’ should say what repeating would help establish. If a measuring instrument lacks appropriate precision, more repetitions alone may not fix its resolution. An appropriate improvement should address the specific weakness shown by the question.
Actual handling of chemicals, electrical components and biological material belongs under trained school supervision. Families can safely revise the scientific thinking through drawings, videos authorised for learning and pre-recorded observations.
21. Scientific honesty when a result is unexpected A surprising reading should be recorded and assessed, not silently changed to match the expected result. Science involves testing ideas, and a discrepancy can reveal an unconsidered condition, instrument limitation or mistaken prediction. It is information to investigate responsibly.
In a fictional exercise, readings of 4.9, 5.0 and 6.5 warrant careful evaluation. A pupil may consider whether the conditions or method differed, but should not invent an explanation without evidence. Reporting uncertainty is often better than claiming perfect reliability.
Such habits matter outside laboratories too. A teenager who can revise a belief when good evidence contradicts it is learning a transferable skill, not merely preparing a model answer.
22. Familiarity with electronic controls The e-exam may use matching, checkbox selection, dragging and other response methods. These can look easy to a student familiar with digital games, but the formal task still demands scientific understanding and reading accuracy. Multiple selections and specific interaction instructions require attention.
Use official school guidance and SEAB-supported familiarisation resources. If the student has an accessibility or technology concern, raise it through the school’s authorised process. Unverified websites should not be treated as exact copies of a confidential examination platform.
One good practice habit is to read the command word, inspect the stimulus, select the appropriate scientific relationship, then use the permitted interface control. A calm method beats fast random interaction.
23. A workable weekly revision rotation A family might use Monday for Machines Around Us, Tuesday for Food Matters, Wednesday for Our Body and Health, Thursday for interpreting a table or graph, and Friday for legitimate e-exam practice. This is illustrative rather than an official five-day school timetable.
Give each session a small objective: explain one energy transfer, distinguish two food-safety claims, or identify an observation and inference. If the child can explain why a correction is valid, that is stronger evidence of learning than the number of screens completed.
Protect time for schoolwork, CCAs, friendships and sleep. Constant drilling can leave a student too tired to read unfamiliar information thoughtfully. Stable short practice with specific feedback often works better.
24. Parent checklist for the 2027 SEC Confirm the K123 registration, the two paper durations and the real school plan for electronic familiarisation. Find out which topics the pupil understands and where the teacher sees recurring difficulties. Avoid buying expensive resources simply because they are labelled ‘new SEC’ without matching the syllabus.
As the examinations approach, practise reading digital questions and writing concise explanations, while continuing to attend supervised practical lessons. Use SEAB and school notices for exact dates; the syllabus specifies paper lengths, not the student’s personalised calendar.
The first SEC results are expected in January 2028. Post-secondary options depend on complete qualifications and applicable admissions criteria. For a distinct comparison, read our G3 Combined Science examination guide. A useful parent conversation focuses on understanding and appropriate pathways, not a promise that one grade guarantees a course.
