The “soda in the aquarium” demonstration will help teachers assess students’ understanding of density and their ability to apply the processes of science. This activity allows students to focus their questions and determine the investigation when the procedures are modified from a cookbook to an inquiry lesson.

The article is about how a student inquiry led to the expansion of a yearly demonstration into a broader inquiry question. The article describes the trial and error process students went through to come up with a process to determine the density of cans of pop to predict which would float. I do not understand why they did not find the density of the unopened can of pop by displacement and the method they chose introduces error but other than that, a fantastic view of what open inquiry can look like in a classroom
