An initiative to build local communities of support that will foster ongoing collaborations among volunteers, students and educators. Volunteers, university students, scientists, engineers, other STEM professionals and, more broadly, members of the community are working together with educators and students to bring discovery-based science experiences to students in grades K-12.
