How Hard Are
Various Types of Rocks and Minerals? |
|
|
|
Introduction
Some minerals are so soft that they are being used as baby powder
and an additive for creams and cosmetics. Some others are so hard
that they are being used as abrasives in making sandpapers and grinding
wheels. Hardness is one of the important physical properties
of minerals and it is sometimes used as a way to identify minerals. |

Material and instructions
Conduct research and run experiments
concerning the hardness of minerals that you can find. Collect some
minerals, test their hardness and try to use the hardness as
a factor that helps you to identify that mineral. Your report
must explain how the hardness is being tested and describe some
of the applications of minerals with certain hardness. |
