grades 3 and up

Meet Marine Science Institute at Pillar Point in Princeton, Half Moon Bay for a guided, hands-on immersion into the rocky intertidal habitat. Instructors guide students through the wet and rocky terrain to discover the fishes and invertebrates that inhabit the tidepools. Using scientific tools including identification keys and transects, students study and safely handle the flora and fauna that are uniquely adapted to the dynamic tidal ecosystem.

In addition to studying the living communities of the tidepool habitat, students also gain an understanding of its structure and formation by stepping into it and watching it change over the duration of their visit.* Through this memorable field trip, students develop an appreciation for this complex ecosystem and their connection to it
