How to Find and Determine the Specific Gravity of a Rock

In the method we use to How to Find and Determine Specific Gravity of Rocks (some call it Specific Density because they don't know better!), we'll use simple equipment. What is required to make this measurement is a weight scale, and the list of the different minerals SPECIFIC GRAVITIES. What specific gravity is, is the mass of a solid in relationship to its weight.
