This lab has students practice determining the properties of minerals. It uses four minerals: quartz, bauxite, hematite and talc. Students are directed to find the color, luster, hardness (not with Moh's scale) and streak of the four minerals. Students are not given the names of the minerals they are using (I called them A, B, C and D). After performing all the tests students then used reference pages in their textbook to determine which minerals they had. An answer key (completed data table) is also included.
