• Resumen

  • Currently, many papers bring discussions on how to approach chemistry knowledge in a High School classroom. However, many concepts related to this knowledge are already part of the approach given to the Elementary School teaching of Sciences. This discussion of chemical concepts together with ones from other areas is important, for it introduces the students to some essential ideas so that they can develop their Chemistry knowledge. Among these, we highlight the study of transformation and composition of materials. For this reason, in this paper we investigate how the first contact with Chemical transformations is established during Elementary School by means of debates involving teacher and students in a Science classroom. Even though the students have shown a few difficulties, we emphasize the importance of this contact for their academic formation
