Processos físico-químicos no tratamento de água e educação ambiental.

Abstract

Believing that the school has a fundamental role in raising awareness of future generations, this paper aims to propose a methodology that provides the student a deepening of his scientific knowledge, in relation to water chemistry and the biological importance of it, in order to contextualize content which apparently has no practical purposes with your reality, spreading one collective awareness towards environmental issues, particularly water, compared the crisis facing society today. For this, we tried to make a comparison between traditional teaching methodology (theoretical approach), traditional methodology of contextualized teaching (theory - environmental context) and methodology under review (theory and practice-environmental context). The content addressed were physical and chemical processes applied in water treatment and preparation of solutions, where it was used water dam and lime, aluminum sulfate, anionic polymer and chlorine to treat it. The activity was developed with 60 students from three classes of the third year of high school from public school in Fortaleza. As data collection instrument was used the questionnaire. The results showed that the methodology in question aroused the interest and motivation of students for discipline and may be a facilitating tool in the process of teaching and learning in Physical Chemistry, besides the formation of more conscious individuals regarding the issue of resources water.
