Uma proposta para ensino de gases abordando a poluição atmosférica e utilizando o cinema como recurso didático

Abstract

The teaching of Chemistry can bring diverse approaches so that the understanding of it and the contents it presents becomes less obsolete and technical, addressed in a vague, fragmented, and decontextualized manner, leading students to have difficulty in understanding it. It is important to make use of various contexts and methodologies that are linked to environmental, social, cultural, and technological issues. In this sense, aiming to assist teachers in constructing a teaching-learning process for high school students, the present work proposes using cinema as a methodological resource to address environmental issues related to atmospheric pollution, linking them to the study of pollutant gases and chemical reactions. The proposal advocates for the use of the film "Air" as an aid to teachers in discussing the lack of concern for environmental issues caused by air pollution, as the formation of gaseous pollutants present in the atmosphere, whether from natural or anthropogenic sources such as industrial and vehicular emissions, contribute to pollution, as do the reactions that occur in the environment, through the emissions of sulfur dioxide (SO2), nitrogen oxides (NOX), carbon dioxide (CO2), and carbon monoxide (CO), through complex chemical phenomena in the atmosphere, thus making it important to address these issues in the classroom.
