3(Cri)Mineral Lab Make Up Chart for Part 1
Part 1:
1. Observe the color of the mineral and record it in the data table below.
2. Record the luster of each mineral as either metallic or non-metallic.
3. Use the laminated card for the Hardness test. Scratch each mineral sample one time to determine the
hardness. Using your fingernail first, and then if needed the penny, and finally the steel nail if needed.
Record your findings on the table below. You will not know an exact #, but can give a range. For
example, record “between 2.5 – 3.0” if your fingernail cannot scratch it, but a penny can.
4. Find a sharp point on your mineral to drag across each streak plate.
You may have to drag the mineral back and forth several times to get results. If you cannot see the mark
on the white plate, try the dark plate. Record your findings on the data table below.
