Tides is a three-hour drop-off marine biology program for children grades 1st-8th with 11 locations: Marin County, San Francisco, Santa Cruz, Monterey Bay, Santa Barbara, Carpinteria, Ventura, Malibu, Palos Verdes, Laguna Beach, San Diego, and Honolulu, Hawaii! Nature journals in hand, students learn about marine creatures, marine plants, birds, tide pools, ecosystems, and sustainability, all in a hands-on, exploratory learning environment. Tides is led by our wonderful and experienced head teachers and assistant teachers who love teaching children about the wonders of marine biology. Tides meets at a different beach each week in order to experience different marine environments. These are small group classes of up to 14 students per group.
