A short summary should still tell the scientific truth
A student writes an abstract claiming a plant-growth experiment proved a fertiliser works. The actual results are mixed. A gold-standard abstract is concise but faithful to the question, method, findings and limitations.
State the research purpose
Explain the question or problem in language the intended reader can understand.
Summarise the method
Identify the comparison, measurements and relevant scope without reproducing every procedural step.
Report the actual result
Use appropriate numerical evidence where helpful, rather than only saying the experiment was successful.
Distinguish findings from interpretation
Describe what was observed and what the evidence may suggest.
Avoid unsupported certainty
Small samples, measurement uncertainty and uncontrolled factors may limit conclusions.
Write after analysing the study
An abstract should summarise completed work, not repeat an earlier prediction.
Break-test: the abstract disagrees with the results table
Can the student correct the summary without altering the observations?
