If I were to teach this in my class, I would introduce this activity by discussing the properties of water and how they can dissolve certain items. This activity did have its own initiating story which would help with self-discovery and independence but I would preface it by discussing dissolving. This activity did not focus on conclusions since it just was a re-testing of someone else's experiment, but did offer up a possibility for more investigation and determining different variables in this experiment. The site that I found this inquiry on had a lot of chemistry based experiments, at different levels, I would definitely use these in my classroom.
