Laboratory experiments in Density require the following apparatus: beam balances, meter sticks, graduates, calipers, tumblers, test tubes, and hydrometers. There should be as many of each as possible· in order to reduce the amount of group work. The objects for study should include pieces of lead, zinc, marble, paraffin, beeswax, glass stoppers, shot, gasoline and solutions of salts such as blue vitriol.
