In this activity, students measure the specific gravity of a sample of the mineral quartz – another physical property of minerals that can be used in mineral identification.

By the end of this activity, students should be able to:

  • explain the meaning of the term specific gravity
  • calculate the specific gravity of a mineral sample from selected data
  • recognise how specific gravity can vary from one mineral sample to another
  • relate physical properties such as specific gravity as an aid in the identification of minerals.
