“…Many undergraduate laboratory experiments focus upon reaction kinetics, − the behavior of acids, ,,, and their reaction with metals. ,− Often, practical work makes the assumption that students already have a fundamental knowledge of the subject and therefore are not required to explain observations at a simple level. However, in supporting the development of trainee teachers, it is of vital importance that they develop the skills and ability to explain concepts in an appropriate way, at a level accessible to their school students.…”

The role of practical work in the training of student teachers is central to the development of their future pedagogy and practice. However, not all laboratory based activities give sufficient challenge in the development of both cognitive and practical skills. The activity proposed in this paper helps reinforce an understanding of reaction kinetics through a study of the reaction of zinc with sulfuric acid. In this study, the observed reaction kinetics conflicted with the typical expectation, which offered a problem to motivate an inquirybased activity.
