Rowell and Dawson (1977a, 1977b) worked on developing students' understanding of density, which was deemed to be a prerequisite for understanding the law of flotation. In their study, Gurdal and Macaroglu (1997) assert that "before teaching the phenomenon, concepts of mass, weight, volume and density, and their differences, should be clarified".
There appears to be general agreement between researchers that an understanding of the law of flotation warrants prior understanding of the distinction between weight and density.
It was interesting that these seven students had progressed this far in reasoning out the law of flotation, without any idea of concepts like mass, density, pressure and volume.
