This brief volume describes an innovative activity that can be used by museum professionals to foster two key inquiry skills—asking a good question and articulating discoveries. A hybrid between a research report and a how-to manual, it describes the development, evaluation, and results of Juicy Question, a collaborative activity designed to foster group inquiry among families or school field trips. The authors demonstrate how the activity changed the behavior of museum visitors and taught them important inquiry skills for use in other informal education settings.
