Part 1: Recording Observations
In the chart below, record your observations of each test for the seven minerals. After you have completed all tests, name the minerals in Part 2 of this worksheet. An example of how to fill out the chart is illustrated below.
|Recorded Observations for Minerals 1-7 | |Tests |Example |Mineral 1 | |Example: Fluorite |80% certain |I am almost certain this mineral is fluorite, but I am not complete sure. Fluorite and gypsum | | | |are both white, shiny, have white streaks, cleave, and show no reaction to acid. However, the | | | |specific gravity of this mineral is 3.18, which is higher than gypsum, so I am pretty sure it | | | |is fluorite. | |Mineral 1: Pyrite |100% certain |I am certain this mineral is Pyrite. Pyrite is the only mineral that is gold with a black | | | |streak and has shiny specks. This mineral is also relatively heavy with a specific gravity of | | | |5.1and a hardness of 6. Pyrite also shows no reaction to acid and fractures as do this mineral,| |...
