Record on your answer sheet whether each sample is a mineral or not based on the definition in your work books. Give the reason for your answers! Specimen Mineral? Yes/No Explain your reasoning Feldspar Crude Oil (no sample) Granite Coal Metal Bar 2. Based on the definition in your work book would a snowflake be a mineral? Explain. ______Station 2 – Color 3. How many specimens are represented in the set? ______4. Observe the color of each specimen carefully. How many different colors are represented in the set? ______5. Based on their colors how many different minerals do you think there are the set? ______6. Is color a good property to rely on when naming every mineral? Explain. ______Station 3 – Streak First, describe the color of each of the minerals in the set. Color Streak a. b. c. d. e. f. Now, rub each mineral on the streak plate one time. Describe the color of each streak on the chart.

7. Which minerals have a visual color different than their streak? ______
