Hidden secrets of soda

Today in Health class, our Fifth Graders used Math and Science to reveal secrets about two popular soft drinks. Using a float tank and an understanding of density, we determined that a can of Diet Coke was more buoyant than a can of regular Coke. We hypothesized that the high fructose syrup content in regular Coke is either more dense or is present in higher quantity than the corresponding artificial sweetener in Diet Coke.  We recognized that neither soda is desirable to drink; we prefer water.
