The Resolution number 3 of the Câmara de Educação Básica (CEB)/Conselho Nacional de Educação (CNE), published in 1998, June 26 (BRASIL, 1998), which established the National Curriculum Guidelines for High School Education, emphasizes the interdisciplinarity, in its 8th Article. However, almost fourteen years later, the reality in most of our schools is the adoption of a merely disciplinary methodology, vis-à-vis the difficulty related to educational planning activities of this kind. In this paper, we present a proposal of an interdisciplinary experimental activity that addresses the concept of surface tension, connecting physicists and chemists. The idea is that students determine the alcohol content of "cachaça" and discuss the concepts of surface tension forces between equal molecules, similar and different. [ABSTRACT FROM AUTHOR]
