**The abstract** is a short description of the paper as a whole: e.g. with one or two sentences each: - The specific area of interest your problem lies in - The specific problem in that area your paper will address - What your contribution is that will help this - The results of your contribution. All four of these together should take no more than about a quarter page, they are a brief description with enough detail so a researcher can decide if they should read the details. **The introduction** is a more detailed introduction to both the problem and your method of solution. You need to demonstrate it IS a problem, preferably by citing statistics or something, and citations to show how others have addressed it, or solved it. Then a more detailed overview (more detailed than the abstract) of your approach and how this differs from previous approaches. **The Body** (which may include multiple parts, the setup, the experiments, the results of the experiments, etc) is all the gritty details a reader would need to duplicate your approach for themselves, do the experiments, and see the results you have produced. Typically this is "streamlined" for compactness, we don't include or mention _failed_ approaches, mistakes, dead-ends or dumb mistakes, just the exact path we found to success. This is not intended to entertain, it is not a chummy letter between friends, it is an official report of work accomplished. **The conclusion** is a recap of just your results, what you believe you have proven ("We have demonstrated that protocols X, Y and Z applied in this order can improve crop yield by 15% to 25%"), and often a statement of **future work** that you intend to do or others might do to extend your research.
