Identical masses with hook

Each mass has the same diameter, the same mass but a different height. They allow working on the concept of density and volumetric mass. They can also be used to study the concept of specific heat. The hooks are intended for additional uses such as studying Archimedes' principle, using them in a Boudreau overflow vase to determine volume, and measuring force with a dynamometer.
