Students in introductory physics laboratories often do not recognize the importance of estimating uncertainties – sometimes dismissing it as busy work. In addition, they often struggle with accounting for uncertainties in their measurements when reporting their findings. Here, we describe the implementation of a new laboratory activity in the calculus-based introductory physics sequence, which was informed by an emerging body of research on laboratory instruction. This laboratory activity focuses on the impact of measurement uncertainties on the construction of a linear best-fit model, particularly when the data points have non-identical uncertainties. In this talk, we will also share preliminary results from pre- and post-laboratory assessments.
