Ask students to determine the density of 15 identical looking plastic specimens of various sizes. Results will vary. When mass vs. volume is plotted for our Density Mystery Set, two lines with different slopes result. This set is comprised of two different plastics which look the same, one with a density of 1.1 and the other with a density of 1.4. At the conclusion of the lesson, the pieces can be dropped into salt-water--half sink and half float. A great lesson in scientific truth and trusting your own calculations!
