World Oceans Day at the New England Aquarium

To pay tribute to the awe-inspiring body of water that surrounds our city, the New England Aquarium celebrates World Oceans Day this Sunday. This installment of the annual outdoor event includes free harbor cruises, a scavenger hunt, and live music. And if all that edutainment causes you to work up an appetite, you can sample sustainable seafood dishes prepared by Aquarium chef Laura Brennan, as well as such culinary talents as Jose Duarte (Taranta), Josh Lewin (Bread & Salt), and Jessica Brown (Treats on Washington). Plus, Ben and Jerry’s will be handing out free ice cream, starting at noon.

Free, Sunday, June 7, 11 a.m.-4 p.m., New England Aquarium, 1 Central Wharf, Boston,

Gender-Swapped Star Trek Performance

See classic Star Trek in a whole new way, as the Post-Meridian Radio Players perform a gender-swapped version of the 1967 episode “Space Seed.” In PMRP’s interpretation, Captain Jane T. Kirk and the rest of the Enterprise crew meet villain Khan Noonien Singh for the first time. “It’s exciting and fun to see iconic, strong, funny characters in an alternate universe, and it’s funny to see the Enterprise as women,” says Mindy Klenoff, director and adaptor of the show. “One actress said, ‘I wish I could play Captain Kirk,’ and we thought, ‘Well, why couldn’t you? If we swapped one, why not do all of them?’”

Free, Friday, June 5, 8 p.m., Saturday, June 6, 2 p.m. and 8 p.m., Unity Somerville, 6 William St., Somerville,

Murder at the Science Museum Scavenger Hunt

Who—or what—is responsible for the disappearance of museum staffers: Benjamin Franklin’s long-lost invention, a serial killer, or the “Curse of the Freemasons”? Solve this murder mystery with a group of friends at the Museum of Science to find out. Use your wits to answer tricky questions and explore the museum in this fast-paced hunt for clues. Ticket price also includes admission to the museum.

$32, Saturday, June 6, 2 p.m., Museum of Science, 1 Science Park, Boston,

Savage Games

For a fun and intense workout, head to fitness space Brooklyn Boulders to compete in the Savage Games. This unique team-based fitness competition—which organizers refer to as a “two-hour beatdown”—takes its inspiration from the likes of American Ninja Warrior, parkour, and obstacle racing. In addition to major bragging rights, winning teams will claim a free one-month membership to Brooklyn Boulders, plus snazzy T-shirts. Get your blood pumping by climbing rock walls, flipping tires, and swinging your way to victory! But first, you must overcome the hurdle that is waking up before 7:30 a.m. on a Saturday.

$35 online ($45 day-of onsite), Saturday, June 6, 7:30-10 a.m., Brooklyn Boulders Somerville, 12A Tyler St., Somerville,
