The purpose of this Summative Evaluation was to assess visitors’ use and perceptions of ‘Living with Hurricanes: Katrina & Beyond’ at the Louisiana State Museum (LSM) as an informal science experience. The exhibition is distinctive in that it is presented in a museum which has been primarily focused on history. The overall experience, affective impact and learning were evaluated for visitors leaving the exhibition. More specific questions of science learning were evaluated in mini-studies in Room 3. This report also examines the degree to which emotion affects informal learning in the museum
