The second Saturday of select months provides an opportunity for the public to visit the learning spaces throughout the science center. This is a great opportunity to enjoy experiences similar to those which engage students during the weekday lessons held in the center’s classrooms and labs. The Living History Farm, Harrison Hall of Natural Sciences, Planetarium, Observatory, and Symmes Hall of Science all provide stimulating activities for fun and learning.
