Why and how scientists communicate
Science grows when people share. Others can repeat an experiment, find mistakes and build on it. Scientists also share with the public, who pay for much research and use its results.
- Know your audience: experts want methods and numbers; classmates want the main idea and a clear graph; children want a simple picture and a story.
- Know your purpose: to inform, to explain, to persuade with evidence, or to ask for feedback.
- Work as a team: share data openly, give credit, and record who did what. Big projects, like the telescopes and particle detectors, need thousands of people from many countries.
Reports, posters and graphs
The usual order
- Title and question: what did you want to find out?
- Method: what you did, so someone else could repeat it.
- Results: tables and graphs, without opinion.
- Conclusion: answer the question, and state the limits (small sample, possible errors).
- References: where your other information came from.
Clear graphs
- Bar chart to compare groups; line graph for change over time; pie chart for parts of a whole.
- Title, axis labels with units (cm, s, °C), even scale, bars starting at zero.
Presenting, demonstrating and exhibiting
- Presentation: open with the question, show one idea per slide, use a graph instead of a table, end with the answer and the next question. Rehearse with a timer.
- Demonstration (for example, a robot or a model): show it working, explain the problem it solves, and be honest about what failed and what you changed.
- Exhibitions and documentaries: use objects, images and short texts; let visitors try something. When you watch a documentary, ask what is fact, what is opinion and what is shown for drama.
- Evaluating others' work: Was the question clear? Was the test fair? Do the results support the conclusion? Give feedback that is kind, specific and useful.
Science in the media and everyday language
Same word, different meaning
- Theory: everyday = a guess; science = a well-tested explanation (theory of evolution).
- Significant: everyday = important; science = unlikely to be due to chance.
- Uncertainty: everyday = we don't know; science = how big the possible error is.
Spotting hype
Headlines may turn may help into cures, a study in mice into a result for people, or a link (correlation) into a cause. Look for the original study.
Check a claim
Who said it, and are they an expert in this area? What is the evidence? How many were tested? Was it peer reviewed? Have others repeated it? Who paid for it?
Try it
Find one science headline this week. Read the article and write the claim in one honest sentence, using words like may or in a small study.
Key formulas and definitions
- Three Cs: Clear, Correct, Checked
- Report order: Question → Method → Results → Conclusion (with limits) → References
- Bar = compare groups; line = change over time; pie = parts of a whole
- Graph must have: title, axis labels, units, fair scale
- Correlation ≠ causation
- Peer review = experts check work before publishing
Worked examples
1. A headline says: Chocolate makes you smarter! The study found that countries eating more chocolate have more Nobel prizes. What is wrong?
It is a correlation between countries, not proof of cause. Richer countries can afford both chocolate and research. No person was tested. An honest version: Countries that eat more chocolate also tend to win more Nobel prizes, but this does not show chocolate causes it.
2. Rewrite for a Class 6 audience: The mean germination rate increased significantly at 25 °C compared with 10 °C.
More seeds started to grow when it was warm (25 °C) than when it was cold (10 °C), and the difference was too big to be just luck.
3. Your team built a line-following robot that failed on sharp turns. How should you present this?
Show the robot working on gentle curves, state the problem (sharp turns), explain what you think caused it (sensor too far ahead, speed too high), what you changed, and what you would test next. Honest limits make your work more trusted, not less.
Common mistakes
- Changing the facts to make them simpler. Simplify the words, not the evidence.
- Graphs with no units or with bars that do not start at zero, which makes small differences look huge.
- Saying proves when a study only shows a link or a small effect.
- Trusting a claim because it is shared many times. Popular is not the same as checked.
