The objective of this article is to investigate the curricular changes imposed by the promulgation of the National Common Curricular Base (BNCC) in the final years of the Elementary School of Sciences in public schools education network, as well as to investigate adequacy of the curricular matrices of some Science teachers training courses to work in Science Elementary Education offered in the state of Santa Catarina. With the qualitative and interpretative study of the documents, it was found that the reform imposed by the BNCC considerably diversified the curricular matrix of Science teaching in Elementary School. This diversification arises with the insertion of Astronomy, Physics, Chemistry, and Geosciences contents. However, curricula of the seven teacher training courses analyzed have a large workload devoted to the contents of Biology. It is considered that this disparity in the approaches of the analyzed courses represents gap for the formation of the future teacher of the final years of Basic Science Education.
