An observation essay should begin by introducing the subject, where and how it was observed and why the writer chose that particular subject. The purpose of an observation essay is to provide an in-depth study on a topic.
Observational essays are the end result of all the information the writer observes about the subject. These essays can be about a person, animal or place. It is not enough to simply see with the eyes; the writer must also pay attention to sounds, smells, tactile impressions and tastes.
After writing the introduction, the writer should address what impressions were the most vivid and why, along with what impact those impressions left. The essay should include a few quotes, if possible, and end with the writer's judgment on the subject.
