O caminho da água até a nossa casa: uma sequência didática para o ensino de Química

Abstract

One of the challenges of the teaching of Chemistry and Elementary Education to the daily life of the students. Chemistry plays an important role in discussing issues or problems for a CTS (Science-Technology-Society). The use of differentiated packaging can play an important role in students' learning as they stimulate their curiosity and learning. One way to integrate this approach, without teaching chemistry, is a discussion of a topic that involves socioeconomic and environmental aspects such as water. Moreover, it is known that Brazil holds much of the world's water and that in the future can be treated like gold in many countries due to a crisis that is beginning to pass. Thus, the main objective of this work was to elaborate and apply a didactic sequence involving the subject water in high school classes in a contextualized way, approaching chemical concepts through experimental and computational tests, aiming at making teaching more attractive and facilitating a Young people more aware and able to perceive a presence of science in their daily life. The application of the sequence, with an average of 20 students, at the Olivina Olivia Carneiro da Cunha's Public School. The results of this study are demonstrated from the lesson that are in a traditional way and that take the students in a communication room of different formative spaces in the school, there is a greater interaction between teacher and student, as well as the learning becomes more attractive.
