Uma proposta de experimento investigativo com materiais de baixo custo para ensino e aprendizagem de eletroquímica

This work proposes a teaching-learning sequence for classes in high school addressing contents, concepts and skills related to electrochemistry aiming to complement traditional teaching classes with the implementation of experimental procedures with low-cost materials. It should be noted that because it is a broad, complex and important content, greater attention should be paid to the way it is taught. During the present work, it was sought to evaluate whether a didactic sequence divided into five stages with the use of demonstrative and investigative experimentation can improve the teaching-learning process of contents and skills, through the proposition of experimental procedures in constructions of electrochemical cells and the qualitative analysis of the contents and concepts emerged at the end of the didactic sequence. It is concluded that the sequence proposal can contribute positively to the development of knowledge because, at the end of the research, some substitutions and complementations of initial conceptions related to electrochemistry are perceived.
