Communicate Scientific Ideas, Findings and Arguments

Scientific communication selects language, structure, data displays and level of detail for a particular audience and purpose. It must distinguish evidence from…

Learning goalsSay it simply

Content, language, structure and digital features are selected to communicate evidence accurately to an identified audience.

By the end of this lesson, you should be able to:

  • Purpose and audience guide content and form.
  • Scientific representations and conventions remain accurate.
  • Editing checks evidence, uncertainty, accessibility and ethical attribution.

Example 1

Worked reasoning model A policy brief on school-zone speed uses force and stopping-distance evidence, a concise graph and a qualified recommendation. A technical appendix supplies method and uncertainty. Layered communication serves decision-makers without hiding the scientific basis.

Curriculum examplesCopied content

Australian Curriculum v9.0 — AC9S10I08: write and create texts to communicate ideas, findings and arguments effectively for identified purposes and audiences, including selection of appropriate content, language and text features, using digital tools as appropriate

Victoria — VC2S10I08, Levels 9–10: Levels 9–10 communication of scientific ideas, findings and arguments for purpose and audience. Victorian Science is banded across Levels 9 and 10, so the VC2S10 code identifies the band rather than a single school year.

NSW: Stage 5 Working scientifically — communicates scientific arguments with evidence using appropriate scientific language (SC5-WS-08). Where NSW places the closest concept in another Stage or spreads it across focus areas, this page states that relationship rather than claiming a false one-to-one Year 10 equivalent.

Questions and answersWith answers
What is the central idea?
Content, language, structure and digital features are selected to communicate evidence accurately to an identified audience.
What should a strong response do?
Use the sequence Define audience and purpose → Select the evidence → Design the text → Review accuracy and impact. Connect the evidence, mechanism or data to the claim.
What common trap should I avoid?
Audience adaptation permits changing the conclusion: Change explanation depth and form, not the supported meaning.
Practice and reviewReady for practice
  • Audience adaptation permits changing the conclusion: Change explanation depth and form, not the supported meaning.
  • More technical vocabulary is more scientific: Prefer precise language the audience can interpret.

Keep the Year 10 boundary: Do not simplify by removing essential uncertainty or units. Do not use visual drama that exaggerates effects.

  1. Communicate the same scientific finding to a Year 10 science class and to a general community audience. Explain and justify at least four differences between the two versions.
  2. Create a concise evidence-based explanation of an unfamiliar dataset for a specified audience, selecting appropriate language, content and representation.
  3. Evaluate a science communication product that is accurate but poorly matched to its audience. Recommend changes while identifying information that must remain scientifically unchanged.

Review hint: Use precise scientific vocabulary, show the relevant mechanism or evidence, and state any limitation or uncertainty when the evidence does not justify a stronger claim.
