The experts at the Great Lakes Science Center are forecasting a mix of science and fun over winter break! At Winter Wonder Days, the whole family can participate in science demonstrations, hands-on activities and other programs to beat the winter doldrums. Guests can also check out the “Curiosity Carnival” exhibition or get a ticket for the Cleveland Clinic DOME Theater’s showing of “Great Bear Rainforest,” a documentary about “spirit bears” of the Pacific Northwest.
