The aim of this work is to discuss issues of language in empirical data in Science teaching research. Such an aim is achieved through the use of core issues within an important methodological language theory that was developed in France around the 1960s: French Discourse Analysis. The central focus is the problem of the non-transparency of language. An analysis of discourses that relate science and the everyday in the school today is presented. After the theoretical investigation and a brief analytical example, a set of still unanswered questions is presented because of their importance in the debate about research methodology in Science teaching and their relationship with teaching itself.
