Marvelous Molecules: The Secret of Life is a 3,500-square-foot exhibition installed on the lower exhibit floor of the New York Hall of Science (NYHoS) between Hidden Kingdoms and Realm of the Atom. The 27 exhibit elements are grouped in sections that feature molecules for sensing, moving, reproduction, defending, and other biological functions. The big idea of the exhibition is: Inside what appear to be very different living things, molecules interact in similar ways to make things happen. In Spring 2001, a summative evaluation of Marvelous Molecules was conducted by Serrell & Associates
