The Cambridge Science Festival, the first of its kind in the United States, is a celebration showcasing Cambridge as an internationally recognized leader in science, technology, engineering, and math (STEM). A multifaceted, multicultural event, the Cambridge Science Festival makes science accessible, interactive, and fun. The Cambridge Science Festival offers a wide range of STEM-related activities (lectures, debates, exhibitions, concerts, plays, workshops, etc.) over nine days at a variety of locations. Modeled on art, music, and movie festivals, the Cambridge Science Festival makes STEM part of the wider culture by illuminating the richness of scientific inquiry and the excitement of discovery. The Festival’s collaborators, MIT, Harvard University, the City of Cambridge, Cambridge Public Schools, Cambridge Public Library, WGBH, and the Museum of Science, reach out to K-12 students, the general public, and the science community, to excite and ignite curiosity. We take curiosity to a new level.
