Esse produto educacional, composto de três aulas teóricas e uma prática, culmina com a montagem de um aparato experimental. Esse aparato é montado facilmente a partir de materiais de baixo custo. O mesmo funciona captando as ondas sonoras e as transformando em figuras semelhantes às Figuras de Lissajous. Para a avaliação desse produto educacional foi utilizada a Teoria da Aprendizagem Significativa de David Ausubel e a pesquisa qualitativa. Dessa forma, foi possível investigar e obter evidências de aprendizagem significativa por parte dos alunos participantes das aulas. === The present research aims at the development and application, with students from high school, of an educational product for the teaching of sound waves under the discipline of Physics. This educational product, composed of three theoretical classes and one practical one, culminates with the assemblage of an experimental apparatus. That apparatus is easily mounted from low cost materials. It works by detecting the sound waves and converting them in figures alike the Lissajous Figures. In order to evaluate this educational product the Theory of Meaningful Learning from David Ausubel was used, as well as the qualitative research. That way, it was possible to investigate and to collect evidences of meaningful learning by the participating students.
