This paper describes the authors' experiences transforming a “cookbook” lab into an inquiry-based investigation and the powerful effect the inquiry-oriented lab had on our students' understanding of lenses. We found the inquiry-oriented approach led to richer interactions between students as well as a deeper conceptual understanding of how images are formed. We observed engaged students participating in scientific discourse full of hypothesizing, modeling, and argumentation based on evidence.
