Development of an Investigative Teaching Sequence about sound waves: the telephone problem in a Science Club

Abstract

In this experience report we describe the development of an Investigative Teaching Sequence (ITS) with five elementary school students participating in a Science Club. Inspired by the proposal of Carvalho et al. (2009), the ITS entitled "The telephone problem" was structured in seven stages that occurred over two Saturdays, whose experiment was the construction of a homemade telephone made of plastic cups and string, under conceptual approaches on sound-mechanical waves, in dialogue with other themes in the interdisciplinary perspective. The reflections allowed us to elucidate that the investigative experimentation by the ITS potentiated several learnings of the clubbing students about physical and interdisciplinary concepts, as well as evaluative, intellectual and manipulative aspects.
