In the chart below, record your observations of each test for the seven minerals provided. 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.
|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|
