Noise pollution and physics teaching

Abstract

Physics teaching has undergone several changes, especially regarding to advances in research designed for this purpose. However, critics of the teaching of this discipline, as well as high rate of failure, can be seen daily in the school context. There are some causes for this situation. In order to present a contemporary educational proposal, aimed at training students for the full exercise of citizenship, in the perspective of meaningful learning, this work aims to bring physics and the environment closer, based on noise pollution and its consequences in everyday life. A problematizing activity was proposed, in order to make students aware of the effects caused by the use of headphones at high volumes. In order to build the scientific response with the students, considering the sound intensity level, they are proposed to carry out an activity based on questionnaires, exhibitions, problematization, texts, videos and at the end an experiment in which, with the use of a sonometer, they must do the measure of the sound intensity level of your headphones in a gradual way from the minimum volume to the maximum, to realize that it is not convenient to use the maximum volume to listen to their music.
