This paper will describe research studying student understandings of solutions. Solutions are a critical part of chemistry, but they have not been studied systematically, particularly in relation to quantification. Based on a comprehensive review of the K-16 literature, we have developed an interview to explore this research question. Students explain a phenomenon that they observe qualitatively. The treatment groups observe the same phenomenon again but with probeware and they explain their observations. The particular activities that allow for data collection will be presented with preliminary data from students.
