The National Zoological Park, a component of the Smithsonian Institution, proposes transforming three traditional zoo exhibit buildings into centers for informal science learning. Based on current knowledge about learning, the proposed project will feature interactive elements as well as the greater use of human interpreters to help visitors examine animals, handle objects and play games. The project is to be a collaborative effort by the National Zoological Park, the Dallas Zoo and Zoo Atlanta, with the National Zoo developing the materials and making and shipping copies to Dallas and Atlanta as centers for tryout and evaluation, with the results of the studies going to other zoos in way of encouraging them of the importance of interactive science education.
