Summer of Sails: Hands-on Fun at the Great Lakes Science Center

May in Cleveland just got more exciting for families craving hands-on learning. The Great Lakes Science Center is rolling out a month packed with boat-themed activities, two big new exhibits, and plenty of chances to get wet while exploring science. The star of the show? The historic Steamship William G. Mather, back for its second season on Lake Erie. Alongside it, a traveling Titanic exhibit opens May 21, giving visitors a close look at real artifacts from the famous ship. Families can build and race their own mini boats in a weekend workshop that mixes creativity with a little friendly competition. Using simple materials, kids and adults can test their designs every Sunday this month. It’s a fun way to learn about buoyancy and drag without realizing you’re doing science. The small fee for supplies keeps things affordable for everyone.Memorial Day weekend brings a special birthday bash for the Mather, which turns 101 years old. The ship’s story is a big part of Cleveland’s past, and the Science Center is celebrating with a mix of shows, games, and tours. One highlight is a wild water-themed science demo that splashes into the basics of chemistry and physics. A scavenger hunt also pops up around the building, sending kids on a search for water-related exhibits. But the real draw? Guided tours of the Mather itself. The ship isn’t just a museum piece—it’s a piece of living history. For an hour, visitors can walk through the engine room, stand in the pilothouse, and see how cargo was once moved across the Great Lakes. It’s a chance to touch the past while learning how big ships powered a city’s growth. For those who love crafts, the weekend includes a session on designing ship flags. Back in the day, each freighter had its own unique flag to show its home port. Now, families can create their own versions, blending art with a little local maritime pride.
