Writing Reports

Written reports are documents which present focused, salient content to a specific audience. Reports are often used to display the result of an experiment, investigation, or inquiry. The audience may be public or private, an individual or the public in general, or in your case, course tutors. 

Reports use features such as graphics, images, voice, or specialised vocabulary in order to persuade that specific audience to undertake an action. Usually a report will have an Introduction, Methods, Results and Discussion section. This structure is standard for the scientific area because it mirrors the traditional publication of scientific research. (Wiki)
