Fully investigate density, buoyancy and specific gravity.

• Allows students to make a wide range of investigations with only a small number of items
• Contains two sets of three metal cylinders - aluminum, copper, and steel

In one set the cylinders all have equal masses, and in the other they have equal volumes. The measuring instruments - cylinder, spring scale, and caliper - measure volume, mass, and length.

This combination of items allows for a wide range of basic investigations, addressing the concepts of mass, volume, density and specific gravity and extending to an exploration of buoyancy.
