This work, using a case report, describes the impact of an itinerant science exposition on a city of Baixada Fluminense (RJ). The methodology used on this investigation was stimulated recall. We have produced a science exhibition about themes of optics in a school where we returned four months latter for further analysis. We aim to evaluate the impact of this exposition in long term, with use of digital photographs of the experiments that made part of exhibition. The results of the investigation have shown that the exhibition has a positive impact on the students, fulfilling its role in fomenting on them the interest in science, besides initiate the knowledge acquisition process on informal science education center based on experimentation
