The Children's Museum will be closed to the public as we renovate, clean, and enhance our current exhibits and galleries. Visit us in the fall for the opening of Time of Giants: Animals of the Ice Age. September 27 to March 7, 2017. Giant Sloths, Woolly Mammoths and Saber-toothed Cats! These gigantic creatures seem to be the stuff of legend, but they were just doing what they could to survive. Take a trip back in time over 10,000 years to the Age of Mammals and explore in this interactive exhibit.
