How does science use language to explain ideas clearly to different audiences, and how do you read and write about scientific and technical information?
Students analyse and compose texts that communicate scientific and technical information, examining how language is adapted for accuracy and for a general or expert audience
A focused answer to the Discovery and Investigations dot point on science communication. How scientific texts use precise language, how the same idea is written for experts and the public, and how to read and compose clear technical information for HSC English Studies.

What this dot point is asking
Science runs on communication. A discovery is useless until someone explains it, and how it is explained changes who can understand it. This elective looks at the language of the sciences: reports, explanations, articles, documentaries. This dot point asks you to analyse how scientific and technical texts communicate, and to compose clear information yourself. A central idea is audience: the same fact is written one way for experts and another way for the public, and matching language to audience is the skill.
The answer
Scientific writing has its own register: precise, ordered and careful with claims. But science also has to reach people who are not scientists, and that is where the interesting choices happen, as a writer turns technical detail into something a general reader can follow.
The language of accuracy
Scientific texts value precision. They use exact terms, measured language, and careful hedging: "suggests" rather than "proves", "may" rather than "will". This is not vagueness; it is honesty about how certain a finding is. They also follow ordered structures, such as the move from question to method to result to conclusion in a report. When you read a scientific text, notice the precise words and the cautious phrasing, because they tell you exactly how strong a claim is.
Writing for different audiences
The same finding can be written for very different readers. For experts, a text uses technical terms freely and assumes background knowledge. For the public, a good science writer explains terms, uses analogy to make the unfamiliar familiar, and connects the idea to everyday life. Notice the techniques of popular science writing: a comparison to something the reader knows, a vivid example, a plain restatement after a technical sentence. These are choices made to bridge the gap between expert knowledge and a general audience.
Reading science critically
The web is full of science claims, and not all are sound. Read with questions: who is making the claim, is there a study behind it, and does the language match the evidence? Watch for the gap between a cautious finding and a confident headline, as when research that "suggests a possible link" becomes a headline that announces a cure. Learning to read the hedge in the original and the overstatement in the popular version is a sharp critical skill.
Composing clear technical information
To explain something technical clearly, know your audience first. For a general reader, lead with why it matters, define each term the first time you use it, use an analogy for the hardest idea, and keep sentences short. Order the information so each step builds on the last. Test it by imagining the reader has no background: can they follow every sentence? If a sentence needs knowledge you have not given them, you have a gap to fill.
Examples in context
Consider one finding written two ways. The expert version reads that a trial "observed a statistically significant reduction in symptoms in the treated group". The public version reads that "people who took the medicine got better more often than those who did not, though more research is needed". A strong response analyses how the second version replaces the technical phrase with plain cause and effect, keeps the honest caution ("more research is needed"), and so makes the same finding clear without overstating it. It contrasts this with a careless headline that would drop the caution and claim a cure. The lesson is that good science communication adapts the language for the audience while protecting the accuracy of the claim.
Common mistakes
Try this
- Take a technical sentence and rewrite it for a general reader, defining each term and adding an analogy for the hardest idea.
- Find a science claim online and check whether the headline keeps or drops the caution of the original finding.
- Underline the hedging words in a scientific text and write a sentence on how certain the claim actually is.

2021 HSC4 marksExplain the ways in which the writer represents Karlie Noon's unique experience.Show worked answer →
A 4-mark Section I question on a feature article about Karlie Noon, an Aboriginal astrophysicist. It is an unseen text, but it is a science-communication feature article written for a general newspaper audience, so it tests this dot point: how language makes specialist science accessible. The marker wants the idea named and supported with evidence.
Make the claim. The writer represents Noon's experience as remarkable by translating a technical field, astrophysics, into plain, human terms a general reader can follow and admire.
Show the techniques. Everyday framing and the headline idea that "anyone can do it" strip the jargon out of the science so the achievement feels accessible. Direct quotation lets Noon explain her own path simply, and the human-interest angle (her background, her motivation) keeps a complex field readable for a non-expert audience.
For full marks, name at least two features (accessible framing, direct quotation, human-interest angle), quote briefly, and keep the focus on how the text communicates science to a general reader.
2023 HSC15 marksChoose ONE of the English Studies modules that you have studied during your HSC year. In what ways did this module interest you and challenge the way you think? In your response, make close reference to ONE text you have studied in this module.Show worked answer →
A 15-mark Section III response. You choose ONE module and explain how it interested and challenged you, with close reference to ONE text. Choosing Discovery and Investigation lets you demonstrate the key ideas of this dot point.
Open by naming the module and your text, then state your line of argument: this module changed how you read science writing by showing that the same fact is written differently for experts and for the public.
Develop with the text. Explain how your chosen science or technical text adapts language for its audience, for example defining terms, using analogy, or controlling tone, and how studying it challenged an assumption you held (perhaps that science writing must be hard to read). Use specific evidence.
Markers reward genuine engagement with both the module and the text, well-chosen evidence, accurate metalanguage, and a sustained, organised response. Avoid summarising the text; argue how it shaped your thinking.
