The Cambridge Science Festival has expanded its schedule, now October 3-9 across more venues in Cambridge. Scan and search the Festival Guide of events — 116 so far, with perhaps more to be added soon. All events are free and open to the public, but several have limited capacity and require advance reservations, via links in the Festival Guide.

The original schedule of events, all at the Kendall/MIT Open Space (292 Main Street), has a different theme each day:

• October 6: Science + Climate — dedicated to all things environmental, renewable, and sustainable
• October 7: Science + Food — the latest in edible chemistry, at a “farmer’s market of the future”
• October 8: Science + Fashion — runway shows, exhibitions, discussion and interaction with designers, makers, engineers, brands, artisans, influencers and the public
• October 9: Science + Carnival — a family-friendly, science-themed, Great American Carnival, noon-4PM featuring a Main Stage, Midway, Side Shows, Walk-abouts, with “competitions and challenges, interactive engineering and hands-on experiments, design workshops and demonstrations, from telescopes to microscopes, from celestial bodies to synthetic bodies, lasers, DNA, the brain, from marine biology to biological machines, from circuit-boards to circus-shows… and very many robots!”
