In this essay, the author describes to biologists the advantages of organic-first curriculum, on the assumption that few biologists are regular readers of "Journal of Chemistry Education" and therefore are probably unaware of the method for integrating chemistry and biology curricula. The author begins with the assumption that the majority of students taking college chemistry are biologists or pre-health-professions students. It is a rare lower-level chemistry course that has more than 20% of its enrollment composed of potential chemistry majors. Thus, first- and second-year chemistry courses are composed of somewhere between 50% and 95% biology-oriented students, depending on the strength of chemical engineering at the institution. However, the author follows this assumption with a conclusion that is startling in its simplicity: if most of the students in the courses are biologists, it is necessary to structure the curriculum so that it is most useful to them.
