The Cambridge Science Festival‘s Science on the Street (SciStreet) program aims to make STEAM accessible, engaging, and fun via appearances at various community events, fairs, and festivals.  Along with the MIT Graduate Student Council and Communicating Science @ MIT (ComMIT), it will host a SciStreet Hackathon to bring students together in teams to brainstorm the design of interactive STEAM activities and demonstrations at SciStreet events.   Each of the top 5 teams will receive $100 to build their design for public display.  The Hackathon will be held on Sunday, September 20, 2-5PM at the MIT Museum (2nd floor classroom; 265 Main Street in Cambridge).  Register online.
