    There is an extensive body of literature that points out the reasons for students' difficulties in assimilating concepts, the presentation of concepts makesthem abstract and unrelated to reality which can cause disinterest in learning. Thus, this research has as objective the application of strategies that are able to overcome this disinterest. Stimulating the students to become involved with the activity and creating hypotheses and questions about the studied phenomena. For that, we use the investigative practice and the activity was carried out in a first-year high school class based on the methodology proposed by Delizoicov, Angotti, and Pernambuco (2002),called "three pedagogical moments", the three steps are problematization, the organization of knowledge and application of knowledge. With the "three pedagogical moments", It is possible to verify the difficulties of the students in the first moment and to stimulate them to evolve in the second and third moment, proving the importance of this approach in the teaching of chemistry. It is important to emphasize that the teacher should be encouraged and prepared so that the actions are effective in the process of teaching and learning.

    Analisando a temática experimentação no ensino de química no conteúdo de eletroquímica dos livros didáticos aprovados no PNLD 2015

    The objective of this work was to verify and categorize the experimental activities contained in the sections of the contents of cells and batteries in four chemistry text books. The content analysis of Bardin (2011) was used for a better elucidation of the data. In three books were found experiments on cells and batteries in an illustrative/descriptive vision and in the fourth book was found a form of analysis of the composition of a cell, being classified as investigative experimentation. With this, we can notice that most of the chemistry text books has expermentations about battery and battery cells in an empirical-inductive way, with only one book bringing a kind of investigative approach.
