A utilização da ciência forense como forma de contextualizar o ensino da Química

Abstract

This work aims to present a teaching proposal aimed at facilitating the teaching of chemistry for 2nd year high school classes, proposing an alternative to alleviate the recurring problem of students' lack of interest in this subject. Thus, the aim is to use the concepts and approaches of forensic chemistry as a way of contextualizing chemistry teaching and showing in practice a functional use of the subject. To this end, we chose to work with high school classes from public schools, in which, initially, 04 classes were developed, in which the use of chemistry through forensic science was shown in practice. To this end, in the first class, students were shown basic concepts of forensic science and their correlations with the discipline of chemistry. Therefore, during this first approach, they will watch videos from television series that showed the use of chemistry in solving cases. In the following classes, experiments directly associated with forensic chemistry were worked on, where students were initially given a small introduction to the content relating to the selected experiments, which were subsequently carried out. In addition, students also answered questionnaires regarding the subject applied in the classroom, which were also seen in practice, through the experiments carried out.
