A necessidade de abordagens que contemplem a transversalidade no tratamento dos conteúdos de ciências aumenta com a aceitação das orientações sugeridas pelos Parâmetros Curriculares Nacionais (PCN). A interdisciplinaridade passa a ser uma alternativa para a efetivação da transversalidade. Entretanto, para ser concretizada como ação pedagógica em sala de aula, a interdisciplinaridade precisa ser sustentada pelo professor, que deve estar subsidiado por material didático e paradidático adequados. Nesse contexto, o trabalho apresenta um estudo interdisciplinar sobre os conceitos físicos de calor e temperatura dentro de um enfoque que ressalta o conceito de sensação térmica. Como mote da discussão, é utilizada a conhecida experiência das três bacias, experiência ainda encontrada em diversos livros didáticos de ciências no Brasil, mas explorada muito superficialmente.
The need for approaches that take in account transversality on science concepts teaching increase with acceptance of National Curricular Parameters (PCN) orientation. The interdisciplinarity became an alternative to accomplish of transversality. However to make concrete transversality as a pedagogical action during classes, interdisciplinarity must be sustained by a teacher that must have support of adequate didactic and paradidactic material. In this context, this work presents an interdisciplinary study about physical concepts as heat and temperature, focusing thermal sensation. It is used the well-known experience of the three vessels as a discussion motto. This experience can be found in many didactic science text books in Brazil, although it is rarely explored.
