Experimentos de baixo custo para o ensino de química por abordagem significativa e por investigação para alunos da 2ª série do ensino médio

Abstract

Due to the problem that many chemistry teachers cannot apply what was discussed in the classroom due to some structural and/or financial problems, the idea of this work arises, which consists of a selection of experiments in the form of a bibliographic survey. where the author, in addition to selecting, also modified them so that the practices have a low economic value, where you will find experiments ranging from R$0.58 to R$19.11, making teachers from elementary schools with few resources encourage their students to teach with experimentation.
