The Science Center of Iowa’s (SCI) largest traveling exhibition to date, “Da Vinci – The Genius,” will end its Midwest premiere run March 20. SCI anticipates increased visitation to the da Vinci exhibition during the final week of its extended run. To accommodate the added demand, SCI will remain open for extended hours through March 20. Information on SCI’s extended hours can be found at www.sciowa.org/about/visiting-information. SCI opened “Da Vinci – The Genius” on Oct. 2, 2010, as only the fifth venue in the United States to host the exhibition. To date, it has drawn more than 50,000 visitors from 27 states.
