On Saturday, April 29, 2017 from 11 a.m. until 3 p.m., the San Mateo County History Museum will present its 12th Annual Maritime Day. This FREE event highlights the Charles Parsons’ Ships of the World exhibit gallery that features 24 model ships hand crafted by expert model maker Charles Parsons. Children will be invited to design their own model ships, make cargo, create miniature lighthouses and learn about knot tying. This year’s Maritime Day is being organized in conjunction with the San Mateo County STEAM festival to be held on Courthouse Square, just in front of the History Museum. The activities introduce kids and adults to STEAM (Science, Technology, Engineering, Art and Math) through fun experiments, speakers and demonstrations.
