In this Activity, students determine the density of different sugar solutions (0-50%). They then dye the solutions and devise a method to combine the solutions to make a multi-colored, layered heterogeneous mixture. This Activity could be used in units dealing with measurement or density. The Activity also underscores the idea that less dense objects float relative to their more dense surroundings. As an extension, students could use standard sugar solutions to determine the sugar content of a commercial beverage.
