Formalized participation in professional service is not often part of the college experience, especially for first-year students in chemistry courses. When service opportunities are offered, they are most often through elective credit, upper-level courses, extracurricular clubs, and the rare service-learning courses. We have successfully incorporated a large science service-learning opportunity into the general chemistry laboratory that provides multidisciplinary educational experiences for children and the community. The experience for the college students involves several weeks of preparation for a two-week laboratory module and participation in the public event on the university campus. College students involved in the second year of the event were surveyed to determine the impact of formalized participation in professional service on their attitude toward science and participation in future professional service events. Highly positive responses on the surveys and public interest in the event suggest continuing and expanding on the science offerings in our geographic location. (Contains 3 tables and 2 figures.)
