This research was aimed at delineate the occurrence of informal teaching of Science in health centers. Through posters and leaflets displayed in these locations, as well as interviews with users, we managed to build an analogy with Science museums and centers under the light of Vigotski's social and historical theory. Scientific dissemination and Science teaching are not the primary objectives of health centers, but the results obtained, indicate that these environments can provide important informal learning situations, especially when it comes to the Health field. Theoretical and practical aspects that have already been observed in studies of museums and Science centers can help us understand the use of this potential.
