Objective 11/29/12 Identify minerals. Intro DO NOT touch lab materials!!!! Pick up worksheet from front table Check and Hand-in Missing Assignments Write Q&A: What are the 7 ways to identify minerals?

Identifying Minerals LAB

Volume 1 = 5.2mL 2 = 8.1mL 3 = 8.4mL 4 = 15.6mL 5 = 20mL 6 = 11.9mL

Identifying Mineral Steps Pick a mineral Color – write down all the colors of the mineral Density Use triple beam balance to find Mass Volume is given Use calculator: Mass ÷ Volume = Density 4. Use the Hardness Test Chart Fingernail = 2.5 Penny = 3.5 Nail = 5.5 Streak plate = 6.5 5. Luster = shiny 6. Streak rub mineral on both streak plates Describe color of powder 7. Texture – feel the mineral (rough or smooth?) 8. Use the chart on the back to match the mineral that comes closest to your descriptions
