The Science Saturday program presents free, weekly events catered to adults, kids, families - everybody! These hands-on activities are fun, accessible science programming with a focus on environmental education, social justice, and fostering community. Activities range from park restoration and cleanups that keep plastic debris out of San Francisco Bay, to climate change science experiments, to learning the science behind healthy cooking and eating, to citizen science excursions like a recent BioBlitz conducted in collaboration with California Academy of Sciences, and more. We focus on collaborations with Bayview Hunters Point community groups and Bay Area nature conservation organizations.

Upcoming Science Saturdays

All Science Saturdays are FREE! No sign up required. See you soon!

Remains of the Bay: An Exploration of San Francisco's Industrial Waterfront

July 1 | 12:00pm - 2:00pm

Join photographer and self-described “armchair historian” Curt Sanford as he shares images and stories about a lesser-known corner of the San Francisco Bay. The photographs in this presentation were taken on a series of kayaking outings along the southeast shoreline and highlight the historical vestiges and ecological transformation of the area. Curt’s images capture the passage of time and expose a hidden world of quiet spaces under crumbling piers, alongside bygone shipyards, and among the many abandoned buildings that line the shore. Come and enjoy Curt’s photographic documentation and learn more about this fast-changing landscape. Join us for light snacks and mingling from 12:00pm-1:00pm, followed by the presentation from 1:00pm-2:00pm.
