A scientific essay needs to be done with a formal writing and in a non-fiction format.
Explanation:
Performing a scientific essay requires precision, clarity and a good level of theoretical knowledge. As this essay is meant to be read in an academic setting, it should be written in a formal manner, with the formal use of grammar and use of elaborate words that guarantee an impersonal and precise tone to the essay. In addition, a scientific essay must be done on the basis of actual facts with scientific proof, so it should not be a fiction.
