Lesson 8 Homework | Mineral Identification Lab

Introduction: Minerals are the naturally occuring inorganic solid elements and mixtures from which rocks are made of. We are going to use minerals physical properties to help identify various minerals samples. . Go to: http://profharwood.x10host.com/GEOL101/Labs/Minerals/index.htm to complete the following lab.

Fill in each of the following tables based on the “virtual tests” you run on each unknown mineral sample that is listed in the cart. You are only doing the five following samples 1, 3, 4, 10, 16. When you get to Mineral Name you need to go back to the Introduction page to try and identify the name of the mineral.
