Uma proposta de sequência didática para o ensino de Química utilizando uma temática ambiental a partir do processo de tratamento de efluentes industriais

Abstract

This work presents a proposal for a Didactic Sequence to expose the theme of improper disposal of industrial effluents in rivers, as well as the presentation of the mixture separation processes involved in the steps of correct treatment of the effluent before discharge into the environment. The objective of this research was the elaboration of an SD from the environmental perspective to sensitize students about environmental problems, recognize a little of the industrial application of contents present in regular chemistry teaching, and allow experimental practices of separation of mixture during the course of the classes. Seeking not only the construction of knowledge, but also structuring the student's critical thinking to form a citizen aware of their active role to collaborate with a sustainable society.
