This article analyses the different teaching strategies developed to the meaning making of content/concept "energy" with activities about batteries and fuel in the 3rd year High School, in a public school. The focus was on dialogic interactions with reconstructive questioning of socioenvironmental knowledge/practice. The study was mediated by the physics and chemistry teacher, during two months of classes. The work is part of a broader qualitative research that included four interpretative sceneries of teaching strategies developed in intra and extra-school contexts. Theoretical and practical activities with dialogical investigation in directed research are analyzed in the mediation and reconstruction of school knowledge, in a critical and reflexive attitude when faced to the socioenvironmental problems in the context of life that need the pedagogical re-meaning in the contemporary society.
