The overarching aim of the present study is to investigate such an invisible object; namely, schoolbags and how their contents function in the lives of pupils between the privacy of the home and the societal world of schools. A sociomaterial approach is used to understand schoolbags as objects that enable certain actions and norms. The uniqueness of the study calls for a more basic approach on the analytical level, carefully investigating and describing the content of the schoolbags as well as their context seeing them as frozen moments of processes. The data material consists of photographs depicting contents of 16 German satchels, which were analysed alongside a description of exterior appearances of schoolbags and the material context of the classroom. The findings show that the function of the schoolbags exceeds their obvious transportation purposes, and that they are complex, entangled objects in the construction of "schooling" and "the pupil".
