Utilização do kit móvel de análise de água como ferramenta de ensino para conteúdo de química do 2º ano do ensino médio

Abstract

The development of this work described in the body of the text, has as principle a approach of chemical concepts from experimental classes, involving classes with practical activities correlated with the students' daily life. These activities were developed in a public school in the city of Teresina (PI), with students of the 3rd year of high school, in the experimental classes were discussed the concepts of pH and electrical conductivity of water. The practical classes were developed in the classroom with the help of the Mobile Water Analysis Kit, allowing at the same time to explain to the students the content in question, leading them to reflection and consequently to the interaction experienced by them on the day -day. The research data were obtained through the application of questionnaires and previous conversation. The results of this evaluation indicated that the students felt motivated with the teaching strategy used, and that it can contribute to a more meaningful learning of the concepts worked.
