This paper describes a graduate-level class project centered on editing chemistry-related entries in Wikipedia. This project enables students to work collaboratively, explore advanced concepts in chemistry, and learn how to communicate science to a diverse audience, including the general public. The format and structure of the project is outlined and assessment metrics are discussed. A panel survey of current students provided an evaluation of the effectiveness of this project in contributing to the learning objectives of the course. Last, a discussion of the challenges involved in implementing this project is provided. (Contains 1 table and 1 figure.)
