# Writing Science Reports

Communicate scientific findings in a structured report using appropriate scientific vocabulary, SI units, and standard notation; describe how peer review and replication contribute to the reliability of scientific knowledge

## Ready when they can

- Writes a structured scientific report including aim, hypothesis, method, results, conclusion, and evaluation using appropriate scientific vocabulary
- Uses SI units and standard form consistently throughout a report
- Explains what peer review is and why replication by independent researchers is essential for scientific claims to be accepted

## Lesson: Writing a Science Report

A science report lets other people read what you did, check your thinking, and repeat your experiment. To do that clearly, every report follows the same structure and uses exact scientific language. The aim states the question you are investigating. The hypothesis says what you predict will happen, before you start. The method lists every step, so someone else can copy it exactly.

*(drawing: Every report follows this order, from the question you're asking to how well the experiment went.)*

The results section reports what you measured, nothing more. Numbers belong here, set out in tables and charts with exact units. The conclusion says what the results show about your hypothesis. The evaluation honestly judges how reliable the experiment was and how it could be improved next time.

Two habits make your report precise. First, always use SI units, like grams (g), metres (m), seconds (s), or degrees Celsius (°C), never made-up or mixed units. Second, write very large or very small numbers in standard form, such as 4.5 × 10^7 m instead of 45000000 m. Exact numbers with clear units beat vague words like 'a lot' every time.

**Example.** A student tests plant growth with and without fertiliser. In the results section she writes: 'Group A (fertiliser) averaged 18 cm. Group B (no fertiliser) averaged 12 cm.' The chart below shows the same data.

A result does not become accepted science the moment one person writes it up. First, other scientists read the report and challenge its reasoning. That checking process is called peer review. Then other labs repeat the experiment, which is called replication. If different teams get similar results, the finding earns trust. If they get different results, scientists hold off on believing it until someone works out why.

**Recap.** A science report has a clear structure, exact SI units and standard form, and only counts as reliable once peer review and replication back it up.
