Scientific communication for purpose and audience — AC9S9I08

Communicate the same science differently when purpose and audience change—without changing the evidence. Choose structure, terminology, visuals and digital tools that make the intended meaning clear and accurate.

Learning goals
  • Identify audience and purpose before selecting a communication form.
  • Use scientific terminology accurately while explaining unfamiliar terms when needed.
  • Select tables, graphs, diagrams and digital features that contribute meaning.
  • Maintain evidence accuracy when simplifying or adapting a message.
Prerequisite knowledge

Recall claim–evidence–reasoning, data representations, source citation and core features of practical reports, explanations and evidence-based arguments.

Key concept

Purpose could be to explain a mechanism, report an investigation, argue from evidence, advise a decision maker or inform a public audience. Audience affects assumed background knowledge, vocabulary and amount of detail. It does not justify changing data or exaggerating certainty.

Scientific texts use features purposefully: headings create structure, tables preserve exact values, graphs show patterns, diagrams explain relationships, captions state significance, citations establish provenance. Digital tools can support accessibility and interactivity, but decorative media that do not add scientific meaning can distract.

Worked examples

Example 1 — class report

For a teacher assessing an investigation, include question, method, processed data, analysis, conclusion and limitations with enough detail to evaluate the evidence.

Example 2 — public explainer

For a community audience, lead with the key finding, define specialised terms, use one clear graph and explain uncertainty in plain language. Keep the result accurate rather than removing caveats to sound certain.

Example 3 — decision brief

For a school leader choosing an energy option, compare relevant evidence, costs/benefits and uncertainty concisely. A recommendation should be traceable to evidence, not hidden behind visual polish.

Common misconceptions
  • Good science writing must sound complicated. Precision matters more than unnecessary jargon.
  • Simplifying means removing uncertainty. Uncertainty can be explained clearly without distortion.
  • More graphs/images always improve communication. Each feature should serve a scientific purpose.
  • Audience changes the result. Audience changes presentation, not evidence.
Guided practice
  1. Rewrite one technical sentence for a general audience while preserving meaning.
  2. Select a graph or table for a stated communication purpose.
  3. Improve a graph caption so it states the scientific message.
  4. Identify an overclaim introduced by an exaggerated headline.
Independent practice
  1. Define purpose and audience for three science-text scenarios.
  2. Rewrite a jargon-heavy paragraph accurately.
  3. Choose two useful visual features for an investigation report.
  4. Write a 60-word public summary of a result including uncertainty.
  5. Transform the same evidence into a decision brief.
  6. Evaluate whether a digital interactive feature adds scientific meaning or decoration.
Reasoning/problem-solving

A dataset shows a modest effect with substantial uncertainty. Produce two communication plans: one for a Year 9 science class and one for a local decision maker. Explain what you would change and what evidence/caveats must remain identical.

Questions and answers
  1. What changes with audience? Vocabulary, assumed background, structure, detail and format.
  2. What must not change? The underlying evidence, data integrity and justified level of certainty.
  3. When should I use a visual? When it communicates a relationship, pattern, structure or comparison more effectively than prose alone.
  4. Why cite sources? To show provenance and let readers check evidence.
Practice and review
  1. Adapt a technical explanation for a younger/public audience without losing accuracy.
    Define terms and simplify syntax; preserve evidence/certainty.
  2. Design the structure and visual features for a scientific investigation report.
    Justify each feature by its communication job.
  3. Critique a persuasive science infographic that overstates a result.
    Identify the mismatch between evidence and wording/visual emphasis, then rewrite it.
Check understanding
  • I identify audience/purpose first.
  • I use scientific language accurately.
  • I choose visuals for meaning.
  • I preserve evidence and uncertainty.

Exit ticket: What can you simplify for a public audience, and what must you never simplify away?

Teacher + parent guidance

Teacher

Have students communicate one dataset twice for different audiences, then annotate every deliberate change. Mark scientific fidelity separately from presentation quality.

Parent/carer

Ask the student to explain one science finding first to you, then as if speaking to a scientist. Notice what changes while the evidence stays the same.
