Ensino de Química água e suas implicações na qualidade de vida

Abstract

This paper describes how the generator theme "Water and its implications for quality of life" was used to promote a discussion from the perspective of Science, Technology, Society and Environment in order to contribute to Chemistry Teaching in citizen perspective. A teaching methodology was developed under the "Institutional Program for Scholarships for Beginner Teachers" and was applied during chemistry classes taught to students of the 2nd year of high school in a public school in the city of Niterói - Rio de Janeiro. The water crisis that hit the Southeast in the years 2014 and 2015 and the importance of basic sanitation as the backdrop for discussions that led to the understanding of the ideal characteristics that water for human consumption should present. Several properties of water have been studied with emphasis on the determination of the pH of various samples brought by the students. Classes had great participation of students, promoting dialogue and meaningful learning about the content involved, particularly with respect to the nature of the acid-base character, because the dimension of this concept took on real meaning, extrapolated to an economic and social context. Keywords: Water. Chemistry Teaching. Environmental Education.
