An abstract is a short summary of your completed research. If done well, it makes the reader want to learn more about your research. I .These are the basic components of an abstract in any discipline: 1) Motivation/problem statement: Why do we care about the problem? What practical, scientific, theoretical or artistic gap is your research filling? ( Some state the background information about the investigation briefly before the motivation) 2) Methods/procedure/approach (and scope of the investigation): What did you actually do to get your results? 3) Results/findings/product: As a result of completing the above procedure, what did you learn/invent/create? 4) Conclusion/implications: What are the larger implications of your findings, especially for the problem/gap identified in step 1?
