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.
