G3 SEC English Two-Audience Explanations

One finding, two different readers

A science club wants to explain an invented demonstration of ice melting. The organising teacher needs a careful account of the assumptions, units and limitations. Younger visitors need to understand why a sample may remain near the same temperature while it changes from solid to liquid. Both readers deserve the same truth. They do not need the same sentence length, amount of technical detail or order of explanation.

Consider a short observation: ‘In this illustrative run, sample B stayed near its melting temperature for twelve minutes, compared with eight minutes for sample A.’ For a teacher, the next sentence might discuss the unequal samples or heat-transfer assumptions that limit the comparison. For a younger visitor, it might explain that the temperature can remain steady while energy changes the material’s state. Neither audience should be told that B is guaranteed to keep food or medicine safe. That conclusion is unsupported by a single classroom-style case.

This chapter develops a particular English skill: changing the route through information without changing its meaning. We will build two versions from one evidence ledger, examine what may be omitted and what must remain, practise making qualifications understandable, and repair misleading sentences. The subject matter comes from Physics and Mathematics, but the writing objective is transferable to any explanation in the G3 English Language examination.

The 2027 SEC English setting

The Singapore–Cambridge Secondary Education Certificate begins in 2027. G3 English Language uses syllabus K300, corresponding to the earlier 1184 code. The official assessment comprises Paper 1 Writing, Paper 2 Comprehension, Paper 3 Listening and Paper 4 Oral Communication. The published weights are 35 percent, 35 percent, 10 percent and 20 percent respectively. For Paper 1, the specified parts include Editing, Situational Writing and Continuous Writing. Situational Writing tasks typically require 250 to 350 words, while Continuous Writing requires 350 to 500 words.

Our two-audience exercise is not a new named SEC task. It practises the syllabus skill of adjusting language to purpose, audience and context, selecting relevant content, preserving meaning, and reading informational text critically. Always follow the format and instructions of the actual question. The published 2027 G3 SEC syllabus list and K300 English Language syllabus are the authoritative examination sources.

What audience adaptation is not

Audience adaptation is not a licence to change the observations. It is not a way to hide an inconvenient result, replace a cautious conclusion with a confident slogan, or invent a benefit that appeals to a particular reader. If a test observed a temperature for twenty minutes, a school notice cannot promise performance for an entire afternoon. If a figure is a modelled estimate rather than a measurement, the public explanation must not call it a reading from an instrument.

The task is to preserve the core relationship among claim, evidence and limitation while adjusting the delivery. A teacher may need a numerical method, a parent may need the decision and its condition, and a younger student may need a familiar analogy. The same conclusion can be shorter in one version and more technical in another. It must remain recognisably the same conclusion.

Begin with an evidence ledger

Before you draft, separate four kinds of information. First are observations: what the fictional table actually records, with times, values and units. Second are calculations: what follows from stated equations and assumptions. Third are interpretations: explanations that connect the evidence with an underlying mechanism. Fourth are uncertainties or limits: what was not controlled, measured or established. Writers often run into trouble when these four categories merge into a single fluent but inaccurate paragraph.

An evidence ledger does not have to be a formal spreadsheet. In an examination it can be four short notes in the margin. For this case: observed time near melting point differs; illustrative heat-transfer model predicts energy by mass; change of state explains an approximately steady temperature; one example cannot validate universal performance. When you adapt for the audience, keep these four truths in place even if the chosen wording changes.

A consistent fictional source

Use the following invented observation for the exercises in this guide. Two samples begin near 0°C and are monitored under a classroom scenario. Sample A remains near the transition temperature for roughly eight minutes; Sample B remains near it for roughly twelve minutes. At minute twenty, the reported temperatures are 6°C for A and 4°C for B. These values are supplied as an original writing source, not as real experimental results. No inference about a product’s quality, safety or commercial performance is authorised.

The initial comparison is simple but limited. B has a longer observed interval near the transition temperature in this one illustration, and at minute twenty its reading is two degrees lower than A’s. Those statements do not establish why B behaved that way, because the masses, geometry and energy-transfer conditions have not been fully specified. Good writing can include that limit without becoming awkward. A reader should be able to tell the difference between what happened in the example and what remains unproven.

Write one faithful central claim

Start with a sentence that both audiences could accept: ‘In this illustrative observation, sample B stayed near the melting temperature for about four minutes longer than sample A.’ The wording names the two samples, the measured feature, the comparison, the size of the difference and the fact that the example is illustrative. It does not imply that a longer plateau is always better.

Now test a stronger but less reliable version: ‘Sample B has the best cooling power and lasts fifty percent longer in all situations.’ The numerical fraction could be drawn from twelve divided by eight, but it refers only to the duration of this particular plateau and the percentage increase is fifty percent relative to A’s eight minutes. The rest of the sentence invents a universal performance claim. Numerical accuracy in one clause does not rescue an unsupported conclusion in another.

What the technical reader needs

A technical school committee needs enough detail to inspect the inference. It may ask whether the samples had equal mass, whether their starting state was the same, what ‘near 0°C’ means, how frequently temperature readings were taken, and whether energy transfer to the container was accounted for. The writer should distinguish observations from assumptions and avoid explaining an observed difference with an unmeasured mechanism as though it had been established.

A suitable opening might read: ‘In the supplied illustrative data, the near-0°C interval was approximately twelve minutes for B and eight minutes for A. At minute twenty, B was recorded at 4°C and A at 6°C. These observations show a difference under the stated example but are insufficient to isolate the cause because sample specifications and full thermal conditions are not supplied.’ The sentence is longer than a public caption because its audience needs a reviewable evidence account.

What the younger visitor needs

A younger visitor first needs the central phenomenon. One possibility is: ‘Ice can take in energy while its temperature stays almost the same. That energy helps it melt. In our example, sample B stayed near the melting temperature longer than sample A.’ This version explains the idea before introducing the comparison. Its sentences are short and its technical vocabulary is supported by a concrete action.

Notice what has not changed. The public explanation still says ‘in our example’. It does not claim that one sample is safe, superior or permanent. It also does not need to explain every constant used in an energy equation. Omission is legitimate when details are not needed for this reader’s immediate question. Omission becomes misleading when it removes a condition essential to interpreting the result.

Use ordinary words with exact meanings

Prefer ‘stayed near 0°C’ to ‘exhibited enhanced isothermal stability’ when the latter adds no useful information. Prefer ‘the ice was melting’ to ‘the system underwent a latent transformation’ for an introductory explanation. Precise language is not the same as complicated language. The purpose of a technical term is to make a useful distinction that ordinary wording might miss.

Keep specialist words when they do essential work. ‘Specific latent heat’ means energy transferred per unit mass during a change of state; it is not a synonym for ‘temperature’. In a teacher-facing report, the term may be useful. In a younger-reader version, explain the idea before or alongside the label. A definition that the audience can understand is more valuable than a string of impressive nouns.

A good qualification is small and specific

Poor qualifications tend to be either absent or oversized. ‘Sample B is always better’ says too much. ‘Nothing can ever be known because every variable might be uncertain’ says too little. A precise limit is more helpful: ‘The comparison describes only the supplied observation; it does not show how either sample will behave in every environment.’ That sentence protects the reader without burying the main finding.

Place the limit close to the claim it qualifies. If you put an unconditional promise in the headline and a careful disclaimer several paragraphs later, readers may carry away the wrong message. In examination writing, relevant cautions can often be expressed in one direct sentence. The goal is to match the certainty of the wording to the certainty of the evidence.

Different order, same facts

The committee may prefer order A: purpose, method, results, limitations, recommendation. The younger visitor may prefer order B: surprising observation, simple explanation, illustrative numbers, what we still do not know. Both can use the same evidence ledger. Changing order is not a change in factual meaning. It is a decision about where the reader is likely to become interested or confused.

A persuasive introduction might say that an unchanged temperature does not mean that no energy is moving. A report introduction might state what was compared and the purpose of the comparison. In either case, each paragraph should serve a clear role. Do not scatter facts merely to sound lively. A familiar route through information helps readers understand difficult ideas without noticing the writing technique itself.

Technical summary: a model of restrained prose

Consider this original committee-facing model: ‘The classroom scenario compares two samples undergoing a change of state. In the supplied illustrative readings, the near-melting interval is approximately eight minutes for A and twelve minutes for B. At minute twenty, A registers 6°C and B registers 4°C. The observed intervals therefore differ by about four minutes, while the recorded temperatures differ by two degrees at that one time. These are descriptive results; they do not establish which physical variable produced the difference.’

The next paragraph could continue: ‘Specific latent heat offers a possible explanation for a temperature plateau during melting. However, the scenario does not provide enough information to assign the difference between samples solely to latent heat, insulation or mass. Any proposal to extend this finding to a new container or a longer period should require an appropriately controlled comparison. The current data are suitable for demonstrating evidence interpretation, not for certifying product or safety performance.’ This version includes both usefulness and limits without becoming defensive.

Visitor explanation: a model of clear language

A visitor-facing version might begin: ‘Why can melting ice stay at nearly the same temperature? Energy is still entering the ice, but much of it helps the ice change into water. A thermometer may therefore show a steady reading during the change. In our classroom example, sample B stayed near the melting point for around twelve minutes, while sample A stayed there for around eight.’

It could finish: ‘At twenty minutes, sample B had a lower recorded temperature in this example. That does not mean it will always be the better option. Different sizes and surroundings can change the result. Our activity is about reading the evidence carefully and understanding why temperature alone does not tell the whole energy story.’ The reader receives the central science without a dense formula, and the last two sentences prevent a new misunderstanding.

Preserve numbers when simplifying

A common temptation is to remove all numerical details for a younger audience. Sometimes that makes sense, but it can also weaken the explanation. Here, ‘about twelve minutes compared with eight’ is an easy and meaningful comparison. It is clearer than saying only ‘B lasted longer’ because the source supports the duration. On the other hand, writing the full energy coefficient in joules per kilogram may distract from the introductory point.

Choose numbers because they answer the reader’s question, not merely because they are available. When you keep a figure, keep its unit and comparison basis. ‘Two degrees cooler’ must refer to a specified time and measured quantity. ‘Fifty percent longer’ must refer to the plateau duration and a named baseline. If an approximation appears in the source, the rewritten sentence should not quietly turn it into an exact measurement.

Reporting a modelled number honestly

The previous Mathematics guide Vol 0423 uses an idealised useful-energy coefficient to calculate the number of whole packs that fit a budget. A technical report can call the result a modelled requirement. A visitor notice could say, ‘Under our example’s assumptions, the calculation has enough energy for four complete packs.’ Neither version should announce that four packs were successfully tested in a real container unless the source actually reports such a test.

Words such as ‘measured’, ‘estimated’, ‘calculated’, ‘predicted’ and ‘assumed’ are not interchangeable. They tell the reader how the number was obtained. Choosing the right one is a form of accuracy. In the K300 examination, this habit also helps when interpreting a passage that combines quotation, survey figures, predictions and the writer’s viewpoint.

An observation is not a recommendation

Suppose sample B has a lower reading at minute twenty. A rushed writer may jump to ‘Choose B for all important transport.’ The evidence is insufficient: we do not know the actual application, performance requirement or safety conditions. A responsible committee statement might recommend a further controlled test rather than an immediate purchase. A public explanation might simply present the observed difference and explain that the activity illustrates phase change.

The correct recommendation depends on purpose. An examination prompt may ask for a decision and provide additional selection criteria. Use those criteria if they are actually supplied. But do not invent criteria because a confident conclusion feels more complete. A shorter, honest recommendation is often stronger than a dramatic claim that cannot withstand an ordinary follow-up question.

Source reliability and attribution

When evidence is invented for a learning exercise, identify it as an illustration. Do not write that SEAB, MOE or a named school conducted the measurements. Official agencies set syllabuses and examination specifications; they are not the authors of our fictional thermal data. Readers deserve this distinction, especially when a site offers both curriculum information and original worked problems.

In a real source-based task, attribution tells readers which voice is speaking. ‘The organiser claimed that B was safer’ is not the same as ‘B was safer’. The first reports a statement; the second endorses it. If the source presents conflicting views, preserve those differences. The English source reconciliation guide Vol 0408 gives another route through this distinction.

Use contrasts that carry meaning

Compare the two versions of a sentence. ‘Although B stayed near the melting temperature longer, this observation does not identify the cause.’ Here ‘although’ introduces a result that might tempt an overclaim, and the main clause states the limit. Now try: ‘B stayed near the melting temperature longer because the insulation was better.’ The word ‘because’ asserts a cause that the given information does not establish.

Connectives do intellectual work. ‘Because’ demands a causal basis; ‘although’ acknowledges a tension; ‘however’ signals a qualification; ‘therefore’ should introduce a conclusion genuinely supported by earlier information. Good explanatory prose does not sprinkle these words at random. It uses them to reveal the relationships between claims, evidence and uncertainty.

Avoid false precision in public writing

The sample durations are ‘about eight minutes’ and ‘about twelve minutes’. If the source provides approximate measurements, do not rewrite them as exactly 8.000 and 12.000 minutes. Extra decimal places are not a sign of authority. The same caution applies to numerical comparisons calculated from rounded inputs. A difference of ‘about four minutes’ is more faithful than an unexplained exact figure.

For a technical reader, you may specify the measurement interval and resolution if the source supplies them. For a public reader, a sensible rounding level may be enough. Either way, do not add precision that the evidence never contained. This practice carries forward into graphs, summaries and reports, not only science demonstrations.

Different levels of explanation

At the first level, describe: the sample’s temperature remained near zero. At the second, explain: during melting, energy can change particle arrangement without raising the measured temperature. At the third, evaluate: the observation is compatible with phase change but does not establish which uncontrolled factor caused the difference between samples. These levels are connected but not interchangeable.

A student may write an excellent particle explanation yet fail a question asking only for what was recorded. Another may faithfully report a number but fail to answer why it happened. Match the command word to the task. For an audience-specific notice, start with the information the reader needs and add just enough mechanism or limit for comprehension. The correct amount of explanation is determined by purpose, not by the writer’s desire to show everything they know.

A full situational-writing model for a school committee

The following is a stand-alone sample for a fictional internal briefing, not a prediction of an SEC examination question. ‘Dear Science Club Committee, I am writing to summarise the proposed phase-change display and recommend how we should describe its results to visitors. Our illustration compares two samples monitored as they warmed from near the melting temperature. Sample A remained near that temperature for approximately eight minutes, while sample B did so for approximately twelve. At the twentieth minute, A was recorded at 6°C and B at 4°C. These are the figures we should use in our explanation.’

‘The observations can help students understand why a temperature reading may remain steady while ice melts. Energy entering a pure substance during its change of state can alter particle arrangement instead of raising the temperature immediately. We should be careful, however, not to attribute the difference between A and B to a particular design feature. The source does not identify all relevant masses and conditions. It also contains no evidence about safe storage of food or medicine.’

‘I suggest that our technical notes state the numerical comparison and its limitations, while the visitor caption begins with the everyday question of why melting ice does not immediately warm. Both materials should identify the activity as a learning illustration. A short question-and-answer section could invite visitors to distinguish an observation from a claim. This would keep the display useful without presenting a single example as proof of universal performance. Thank you for considering this approach.’

Notice the construction. The message states its purpose, presents relevant evidence, explains the scientific point, identifies the limits and offers a concrete action. A real K300 situational-writing task may prescribe a different format, audience, content and word limit, so follow that actual prompt. The sample demonstrates task fulfilment and honest selection rather than a rigid template to reproduce.

A full visitor-facing model

The companion text reads: ‘Why does melting ice sometimes stay at almost the same temperature? Because the energy going into the ice is helping it change into water. The thermometer may not rise much while the change is happening. Temperature tells us something important, but it does not show every part of the energy story. In our invented school example, sample A stayed near the melting temperature for about eight minutes, while sample B did so for about twelve.’

‘At twenty minutes, sample B also had a lower recorded temperature: 4°C rather than 6°C. Does that prove B is the best choice everywhere? No. Samples with different sizes or surrounding conditions may behave differently, and our example does not test every possible situation. The aim is to understand why a change of state can take in energy without a big change on the thermometer.’

The visitor version leads with a question, explains the phenomenon in familiar terms, gives only the most useful figures and closes with a limit. It is shorter and warmer in tone, but it does not bend the evidence. The difference between the two versions is their reader’s likely knowledge and purpose, not two incompatible stories about what happened.

The paragraph-by-paragraph fidelity check

After drafting both versions, compare their claims line by line. Are the same samples named? Do both preserve the approximate eight- and twelve-minute durations? Do they describe the minute-twenty readings accurately? Does either version attribute a cause not established by the data? Does either suggest a safety guarantee? An adaptation that fails these checks is not simply a stylistic difference; it changes meaning.

This method resembles the source-fidelity habit in comprehension and summary. When compressing a passage, preserve its essential conditions and relationships. When expanding an explanation for a new reader, add accessible definitions rather than new facts. It is safer to write from a short evidence ledger than to rewrite from memory after the first draft.

Editing that preserves certainty

An editor can improve flow while accidentally changing modality. ‘May remain near zero’ is weaker than ‘will remain at zero’. ‘In the supplied example’ is narrower than ‘in every trial’. ‘The sample was recorded at 4°C’ differs from ‘the sample is always 4°C’. These small edits can change the claim even when the broad topic remains the same.

Review modal verbs, quantifiers and tense. Ask whether words such as all, none, always, never, can, may, must and proves are earned by the source. Use present tense for a general explanatory principle if appropriate, and past tense for what a particular trial recorded. That distinction helps readers know whether you are describing an example or making a general statement.

Good concise writing is not oversimplification

Students sometimes think that formal readers need longer sentences and public readers need babyish language. Neither is true. A technical explanation can be direct, with one main idea per sentence. A public explanation can respect the reader by giving the exact useful distinction. The difference is how much prior knowledge and supporting detail each version assumes.

Clear writing also avoids unnecessary signposting. You do not have to announce, ‘I will now discuss my next point,’ when the paragraph already makes that transition. Give readers the evidence, a relevant explanation and a conclusion that fits. The best sign of control is that the reader understands the subject without struggling against the prose.

Under timed conditions

In the examination, underline the audience and purpose before writing. List the required content points from the prompt and mark which ones can be used as evidence. Decide the appropriate form, opening and tone. If an unfamiliar technical source is provided, define necessary terms but do not invent new scientific facts. Draft around a clear central message, then read again for omissions and unearned absolutes.

Editing should protect task fulfilment, grammar and meaning. Check sentence boundaries, pronoun reference, verb tense, comparison basis and units. The English comparative-writing guide Vol 0420 develops the numerical reporting foundation, while the English reports and proposals guide offers wider practice in purposeful structure.

A bridge from PSLE to secondary explanation

Primary-school work already teaches that a comparison needs a clear basis. The PSLE learner guide on naming both things being compared is the simplest form of today’s discipline. The G3 version adds audience, uncertainty, calculated versus observed values, and the temptation to turn a result into an unjustified promise.

Read Vol 0422 for phase-change Physics and Vol 0423 for energy-budget Mathematics. The next EMS guide tests whether a combined case has kept its measurements, modelled values and public statements aligned. The point of the sequence is not to rewrite the same article; each stage adds a different intellectual demand.

Frequently asked questions

Can a shorter explanation still be accurate? Yes, when it retains the claim, basis and relevant limits. Must a school notice include every equation? No. Include equations only if they serve the audience and task. Is a personal analogy a substitute for the given data? No. It may help the reader understand a mechanism, but it should not replace a supplied result. Should you write ‘proved’ after one classroom illustration? Not when the claim goes beyond what the evidence establishes.

Does audience adaptation apply only to science topics? No. The same skill matters when summarising a survey, explaining a timetable change, proposing a school activity, describing an environmental issue or discussing a writer’s viewpoint. The subject changes; the duty to preserve meaning does not. If the revised text is easier to read but says something materially different, it is not yet finished.

Practice 01: Headline versus technical finding

Source: B stayed near 0°C for roughly twelve minutes while A did so for roughly eight. Weak headline: ‘B defeats A in every temperature test.’ A faithful visitor headline is ‘Why ice can stay near one temperature while it melts’. The technical finding could say that B’s observed near-transition interval was approximately four minutes longer in this illustrative run. Compare the two. The headline invites curiosity about the mechanism; the finding records a specific comparison. Neither promises a universal ranking.

To check your work, write one version for a reader who needs the decision and another for a reader who needs the method. Then compare nouns, numbers, conditions and verbs of certainty. Ask what stayed true, what became clearer, and whether any detail was dropped that changed the claim. You should be able to justify the differences in tone or order without needing to defend a change in facts. This is the test of faithful communication rather than decorative rewriting.

Practice 02: A missing denominator

A student writes, ‘B performed fifty percent better.’ The ratio twelve divided by eight does yield a fifty-percent increase, but only for the observed duration near the transition temperature, using A’s eight minutes as the base. Repair the claim: ‘B’s near-melting interval was about fifty percent longer than A’s in the supplied example.’ This names the measured feature and basis. Then decide whether a public explanation might be clearer with ‘twelve minutes compared with eight’ instead.

Practice 03: Observed and predicted times

A technical worksheet predicts that a pack may remain near a threshold for fifteen minutes, but the fictional observation records twelve minutes. Do not merge the figures into ‘the pack lasted fifteen minutes’. A report should identify the fifteen-minute value as modelled and the twelve-minute value as observed. A visitor explanation might omit the prediction entirely if the purpose is to discuss the observation. If you include both, use a clear contrast: the model predicted fifteen minutes, while the trial recorded about twelve.

Practice 04: A younger reader asks why the temperature is constant

A visitor asks, ‘If the thermometer stayed at zero, was the heater doing nothing?’ Explain simply: ‘Energy could still be entering the ice. During melting, it helps turn solid ice into liquid water instead of immediately making the temperature rise.’ Avoid saying that ice contains zero energy or that no particles move. If a technical committee asks the same question, add a particle-energy explanation while retaining the same physical meaning.

Practice 05: Technical omission versus misleading omission

A teacher-facing report includes mass, useful power assumptions and the difference between measured and calculated energy. A short caption for primary pupils may leave out the numbers needed for advanced calculations. That omission is reasonable if the caption does not use them to make a quantitative promise. But omitting the words ‘in this example’ from a claim about sample performance can mislead readers into assuming a general finding. Identify which omitted detail affects meaning.

Practice 06: Dangerous certainty word

A visitor caption says, ‘Ice always remains at zero degrees until every piece has melted.’ This is too general: material conditions, pressure, purity and measurement circumstances matter. A more accurate instructional sentence is ‘Pure ice may remain near its melting temperature while it melts under the stated conditions.’ Explain why ‘may’, ‘pure’, ‘near’ and ‘under the stated conditions’ are not empty hedges. They identify the boundaries of the idea without making the sentence difficult to read.

Practice 07: Different order for different purposes

A committee report begins with objectives and data, then the explanation and limitations. A visitor leaflet begins with a question about melting, then a simple explanation and relevant numbers. Draft the opening sentence for each. Keep the same source values even though the order changes. A writer may choose different structures because readers have different needs; however, a lively opening does not justify changing the observation or deleting a limitation essential to the claim.

Practice 08: A cause that was not tested

The supplied data give only two plateau durations, eight and twelve minutes. A student writes, ‘B’s insulation caused the longer plateau.’ The source does not supply the variables needed to isolate insulation as a cause. Repair it to a descriptive sentence, then add a separate possible explanation if the task asks for hypotheses: ‘Different heat-transfer conditions might contribute, but the data do not identify the cause.’ Separate observation, explanation and speculation.

Practice 09: Source attribution for a quotation

The organiser says, ‘This will work everywhere.’ A writer summarises: ‘The test shows that it works everywhere.’ This changes the status of a statement from an attributed claim to an established result. Write instead, ‘The organiser claimed that the method would work everywhere, although the supplied data do not establish that.’ Attribution protects accuracy. It is particularly important when reading an informational source that contains several voices.

Practice 10: A comparison without a time

At minute twenty, A was recorded at 6°C and B at 4°C. Weak sentence: ‘B is two degrees cooler.’ Stronger sentence: ‘At minute twenty of the illustrative observation, B was recorded at 4°C and A at 6°C, a difference of 2°C.’ The second version identifies the time, the object, the measure and its unit. Decide what may be shortened for a caption without losing the source’s limitation. ‘At minute twenty, B was two degrees cooler’ is concise and defensible when the samples are already identified.

Practice 11: An unjustified safety recommendation

A report says, ‘Use B for medicine because it stayed cooler in this demonstration.’ The conclusion is not supported: a fictional classroom comparison does not establish safe storage or a verified temperature range. Replace it with an action that follows from the evidence: ‘Use the comparison to explain the phase-change idea; undertake appropriate controlled testing before considering practical performance claims.’ A writing task can ask for a recommendation, but the recommendation must still fit the supplied facts.

Practice 12: A quotation for the public and one for the committee

Technical version: ‘The source provides a single illustrative set of time and temperature readings; replication and controlled conditions are not specified.’ Visitor version: ‘We only looked at this one example, so it cannot tell us what happens every time.’ Both communicate the limitation. The technical version names the methodological issue; the public version uses common language. Check that neither claims extra facts about tests that were not performed.

Practice 13: Avoid passive fog

The sentence ‘A difference was observed in the results’ does not tell the reader who or what differed. Write ‘Sample B stayed near the transition temperature for about four minutes longer than sample A in the example.’ The rewritten sentence uses an active, specific comparison and gives the relevant scale. Passive constructions are useful when the receiver or observation matters more than the actor, but they should not be used to conceal the subject of the sentence.

Practice 14: Make a technical term teach rather than intimidate

A notice reads, ‘The latent heat of fusion causes an isothermal interval.’ A younger reader may struggle. Rewrite: ‘As ice melts, it takes in energy without immediately becoming warmer. The energy helps the solid change into liquid water.’ If appropriate, add: ‘Scientists call the energy involved in that change latent heat.’ The technical term now follows the concept. The explanation is not less precise simply because it is easier to understand.

Practice 15: Explain the percentage base

A report says that an interval increased from eight to twelve minutes. The increase is four minutes. As a fraction of the original eight minutes, that is 4/8 = 50 percent. A careless rewrite says that the total time is fifty percent of the old time, which is wrong; it is 150 percent of the old time. For a public notice, ‘four minutes longer’ may be clearer. Both versions should use the correct relationship.

Practice 16: A claim that needs two sentences

A learner writes, ‘Although the example is fictional and does not specify masses or insulation or monitoring conditions, sample B staying near zero twelve minutes and sample A eight minutes suggests certain possibilities but no universal guarantee.’ Break it into two or three sentences. State the observation first. Then state what the source cannot establish. The result is easier to read and less likely to blur measured facts with speculation. Clear sentence boundaries can improve precision, not merely style.

Practice 17: Revise a paragraph for a different audience

Committee version: ‘The eight- and twelve-minute transition intervals are descriptive rather than controlled comparative evidence. No causal attribution is warranted.’ Visitor version: ‘One sample stayed near the melting temperature longer in our example. We cannot tell from these numbers alone why that happened.’ The visitor version keeps the limit and removes jargon that a younger reader might not need. Explain which words changed and which underlying claim did not.

Practice 18: When a question asks for a persuasive proposal

Suppose the teacher asks you to propose a science-club exhibition. Persuasion is allowed, but evidence remains essential. Argue that the display would help visitors learn the difference between temperature and energy, and that the text can present both a simple caption and an optional technical note. Do not claim that the activity has been formally approved or that it guarantees improved results. A strong proposal names the audience, benefit, feasible action and reasonable safeguard without manufacturing authority.

Practice 19: Listening and spoken explanations

The same adaptation skill appears in oral work. A presenter might say: ‘The ice can keep melting even while the temperature hardly moves. That is because energy is helping it change state.’ If a teacher asks a follow-up, expand: ‘The change involves particle arrangement and latent energy, so temperature alone does not describe the full transfer.’ Do not recite a dense written paragraph aloud. Use natural phrasing while preserving the mechanism and limitation.

Practice 20: Final fidelity audit

Compare two finished pieces. Both should identify the example as illustrative, retain the observations they choose to report, distinguish a change of state from a temperature rise and avoid unsupported universal claims. The technical piece may discuss missing controls; the visitor piece may explain melting with simple words. If one version says B is always safest while the other calls the evidence limited, they are not successful adaptations. Repair the contradiction before polishing style.
