Discovery Day Open House

Experience science in action at the only marine laboratory on the San Francisco Bay, SF State's Estuary & Ocean Science Center. As this is SF State's 40th Anniversary supporting estuary and ocean science on the bay, the activities will be focused on comparing SF Bay and marine science as they were, then and now.

Try your hand at making a measurement. Learn about the tools of the trade. Help collect data to answer a research question. Play a game and learn a new concept. Explore the patterns in nature. Learn about solutions to environmental challenges.

Collect microscopic life from the Bay (plankton) and view it on microscopes, hold and measure invasive green crabs, enjoy collaborative art projects and design challenges, and be among the first to see the work of the California Coastal Commission's K-12 2018 Coastal Art & Poetry Contest!

Admission and parking for Discovery Day is FREE, but registration is required!
