A research paper is a good way to present your project. It can follow the more academic research paper formats used by colleges but in general it is a sequential presentation that starts from your purpose or hypothesis and ends with a summary of your results and analysis. In between, the paper should present the methodology, results and analysis followed by your conclusions. Typically the paper is divided into sections covering each of these areas.
We include some examples here and you can take a look at prior competitions on this site for papers or presentations included with those projects.
