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 completely 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: |100% certain |I am certain this mineral is Pyrite. It was the only gold mineral with the color gold, streak |

| | |black, luster shinny specs, specific gravity about 4.9-5.2 my results were 5.1, cleavage & |

| | |fracture test...
