An abstract lets a reader decide what was done, what was found, and whether the full project is relevant. It is not an introduction with the results removed.
Use five moves
- Problem and context: one or two sentences establishing the specific need.
- Question or design goal: the exact objective.
- Method: the study design, sample/data, comparison, and primary metric.
- Major result: the most decision-relevant quantitative outcome, with uncertainty when appropriate.
- Conclusion: what the result supports, its boundary, and the implication.
Draft the result and conclusion first. They determine which background and method details deserve scarce words.
Compare two abstracts
Weak
Plastic pollution is a huge problem around the world. In this project, different biodegradable materials were investigated using many tests. The results were significant and showed that our new material performed much better. This material could revolutionize packaging and save the environment.
The question, comparison, test conditions, numbers, and limitations are absent. “Significant” and “much better” carry no inspectable meaning.
Improved
Low-cost compostable packaging must retain strength during use while degrading under disposal conditions. We tested whether a starch–fiber composite could maintain tensile strength for seven days and lose mass during controlled composting. Three formulations and a commercial paper baseline were tested across 12 independently prepared specimens per condition. The best formulation retained 82% of initial tensile strength after seven days and lost 31% mass after 28 days, compared with 94% strength retention and 8% mass loss for the baseline. Under these laboratory conditions, the composite improved degradation at the cost of lower short-term strength; moisture sensitivity, toxicity, and manufacturing scale remain untested.
The improved version gives the reader something to evaluate. The numbers are illustrative; your abstract must use your own verified results.
Keep ownership and rules visible
Describe only the work you performed. If a mentor’s laboratory supplied data, equipment, code, or procedures, follow the destination’s acknowledgment and authorship rules. Do not blur the mentor’s work into the student procedure.
Every fair, journal, conference, or workshop has its own length, format, content, and authorship rules. The Society for Science abstract guidance is specific to ISEF, including its 250-word limit; it is not a universal submission rule. Use the actual destination instructions linked from the opportunity.
Cut without hollowing it out
Remove broad opening claims, literature lists, procedural trivia, undefined adjectives, repeated conclusions, and future-work wish lists. Keep the comparison, sample, primary metric, major number, and boundary of the claim.
