Construção de Roteiros de Atividades Demonstrativo- Investigativas para o Ensino dos Gases.

Abstract

Chemistry is a discipline that is difficult to understand and requires a high level of abstraction. With this, this work sought to offer Chemistry teachers of Basic Education some suggestions for experiments with an investigative focus. The general object of this work was to elaborate scripts of demonstrative-investigative activities for the teaching of gases, and as a result, it was sought to problematize the importance of experimentation in the teaching of chemistry, to reflect on the demonstrative-investigative experiment as a didactic strategy for the teaching of gases and preparing activity scripts as a didactic tool for experimental classes to study concepts related to the properties of gases. For this, a bibliographic review was carried out, with a qualitative approach, for students of the 1st year of high school, thinking about the lack of laboratories in schools. It is expected that the proposal, using the scripts for demonstrative- investigative activity in chemistry classes in the teaching of gases, will help the teacher in his classes in the perspective of working on the possible skills of the three levels of chemical knowledge.
