In teaching physical and natural sciences, there are several studies that indicate the strong presence of spontaneous concepts in cognitive structure of high school students and even among teachers that level of basic education. This study aims to diagnose spontaneous conceptions and cause the students, within limits and some possibilities, cognitive conflict on the subject microgravity. In reviewing the literature, only we highlight the concepts that are related to the theme microgravity. Working in a constructivist perspective, based on the theory of Piaget balancing, discussing issues related to the theme proposed by videos that have been produced in the laboratory from an experiment designed to simulate the microgravity environment. Were also used Other Videos paragraph contextualization do subject. The use of videos in the classroom, In addition to the possibility of offers - them virtually, is currently presented as a powerful tool in the process of teaching and learning. The effectiveness of the product with regard to learning in the classroom, was tested by applying a questionnaire. The results were used to show the evolution of the cognitive structure of students by means of graphs. We conclude that innovative approaches to teaching in general and more specifically to the teaching of physics are actions which contribute significantly to improving basic education.
