Abstract
Houses painted with lead-based paints are ubiquitous in the United States because the houses and the paint have not worn out two decades after federal regulations prohibited inclusion of lead in paint. Remodeling older homes thus poses a health threat for infants and small children living in those homes. In a service-learning general chemistry class, students disseminate information about this health threat in an older neighborhood. At some of the homes they collect paint samples that they analyze for lead both qualitatively and quantitatively. This service-learning experience generates enthusiasm for general chemistry through the process of working on a "real" problem. Sample collection familiarizes the students with the concept of "representative" sampling. The sample preparation for atomic absorption spectroscopic (AAS) analysis enhances their laboratory skills. The focus of this paper is on the mechanics of integrating this particular service project into the first-term of the normal general chemistry course.
