graduated cylinder definition
Fill a graduated cylinder (say about a 100ml graduated cylinder) with water, and weigh the 100 ml of water. You will of course find that it weighs 100 gm because the DENSITY of water is 1 gm / 1 ml. You can repeat this step of the experiment with a soluble salt. Epsom salts (MgSO4*7H2O) is a good choice because it is readily available, cheap, and not toxic -- available at any pharmacy or grocery store. Make a concentrate solution (it need not be saturated, in fact it should not be). Weigh 100 ml of this solution. It will be heavier than the 100 ml of pure water. This demonstrates that solutions (liquids have different densities). Depending upon the type of balance/scale you have you may have to make a correction for the weight of the graduated cylinder (tare weight). Now the fun begins. With the graduated cylinder about half full
(say 50 ml) drop in the objects. You will notice that the volume
as it appears in the graduated cylinder will increase. That increase
is the volume occupied by the objects, it is the volume of water
displaced by the beads. The weight of the objects measured in
air
