Seacoast Science Center is celebrating World Ocean Day with a free family festival focused on the wonders of the ocean and how we can help keep it healthy for future generations. Activities will include a mock seal rescue for kids, tours inside a life-size inflatable whale, family march for the ocean, face painting, games, meet-and-greet with mascots, beach clean-up and more. There will be an official opening of the Center’s newest exhibit, H2O Today, at 11 am. Live music will be provided by band Bliss from 12:30-2 pm, Lexie’s Burger Bus will be on-site with lunchtime favorites, and there will be popcorn, cotton candy, ice cream and cold drinks available for purchase.
