The Bay Area Collaboratory (Kahn & Rockman, 2003; Kahn, 2005) supports San Francisco Bay Area (as well as other California) science teachers and students, parents, museum educators, and other informal science providers by collectively helping teachers and other users easily find and aggregate the best standards-aligned, web-based learning and teaching resources from multiple Bay Area science-technology and children's museums, aquariums, zoos, and other "best of the Web" resources for use in formal science education in the classroom.
