Write a coherent narrative about public health issues or things related to public health the narrative should includes:
What you did: where you went, how you set up to do your observation, and perhaps why you made those choices.
A general description of the scene — this should give me enough to understand what you were seeing. Diagrams and photos can be a big help.
A summary of what you observed – of your factual observations.
Then interpretations and conclusion about what you saw. This is more than just description, but doesn’t have to be earth shattering.
Include your field notes as well.
