The abstract should give readers a thorough summary of everything the project incorporated. It is typically limited to 250 words.
Begin by giving readers context on the project and its position in the larger scientific picture. This will act as a miniature literature review that will give audience members just enough information to understand your work.
Next, summarize your methods; there is no need to give specific measurements or describe any procedures that are considered commonplace within the scientific community.
Then, include your results and error margins, as well as potential errors. Explain trends and draw conclusions.
Finally, end by discussing the project's implications and the future research this could inspire.
