In sciences that are area of interest in this research, if it has invested little in such a way in concrete materials that stimulate the interaction between the object and the citizen how much in qualification of the professor, whom in its majority it prefers not to approach definitive contents for not feeling itself prepared. As for the contents related to the physics, in accordance with Parmetros Curriculares Nacionais (PCN), is perceived that these are general traces of science, approaching as if it understands world in its representations, the universe the time the substance, that is, to know the phenomena natural to place itself as to be integrant of the way. These concepts are shyly boarded in many didactic and rare boarded books for the educators. This because many if do not feel able for such, and when these concepts is boarded, this is made of form ‘ ‘ mecnica’ ‘ , that is, one reproduction, what no interest on the part of the pupils does not awake. One gives credit that the activities based on the exploration of concepts can appear as alternative to the form as the professors have attemped to approach contents related to the physics. Such activities, that must be incentivadoras and that the children for the scientific knowledge can instigate, are the investigativas activities, that aim at the stimulaton to the experimentation, the test, the logical thought and the resolution of situation-problem. According to Piaget (apud Wedge, 2002), the contact with the concrete contributes better for cognitivo development because the abstract in the period of 7 the 10 years of age if becomes complicated.
