There are many things that can influence a child's career path. Parents and teachers are first to come to mind. But simple exposure to a certain career may also influence a child's choice of a career. There is always a need for science, technology, engineering, and math (STEM) jobs. We look at elementary students who have attended an expo designed for STEM exposure and consider the effects the expo has had on their interest in certain careers. Surveys were obtained from elementary students who attended a local Engineering Expo and students who did not attend this Expo. We also compare the career interests of students who have had STEM exposure at the Expo to those that have not had the exposure. Comparisons are made between two elementary schools (those exposed and those not exposed), grades, and genders. Differences occur in some of these areas, but not all.
