Once you have drafted a working thesis, you may want to devise a tentative outline drawing on your invention and research notes. An effective outline for a concept explanation should be divided into separate topics that are conceptually parallel. Patricia Lyu, for example, forecasts her topics in two rhetorical questions: “How does that bond develop and how does it affect romantic relationships later in life?” (par. 1) From this sentence, readers know what she will focus on. Toufexis focuses on the scientific foundations of love, and so she divides the topics she will cover into evolution, biology, and chemistry. Once you have decided on your topics, present them in a logical order (for example, from most familiar to least familiar).
Below is a simple scratch outline for an essay explaining a concept, which you may use as a starting point:
Use your outline to guide your drafting, but do not feel tied to it. You may figure out a better way to sequence your topics as you write.
