This study examines the actions and discourse of students in a chemistry laboratory course as they interact with available social and material resources. In one session, students conduct wet lab experiments; in another, they use molecular modeling software. The analysis demonstrates that the features of the computer-generated representations afford conceptual discussions. The structure of the task and the available material resources in the wet lab more often result in help-seeking behavior.
