Abstract:

Understand how the same object can both sink and float, depending on its density relative to a fluid. Seawater contains many dissolved substances and these add mass to the water producing a greater mass per unit volume, or density, than that of pure water. The relationship between the density of a fluid, weight of an object, and buoyancy is critical in understanding the ocean, because density has a direct influence on the way seawater and objects in seawater behave.
