1 Formation of Minerals Drill: Name one place you might find minerals. What does this suggest about how they form? Objective: SWBAT identify ways minerals can form in order to create a flow chart on mineral formation. HW: none.

2 Mar. 17 th, Formation Drill: Describe one way a mineral can form. Objective: SWBAT identify ways minerals can form in order to create a flow chart on mineral formation. HW: 2-2 due Friday

3 Minerals from Metamorphism Beneath Earth’s surface undergoing extreme heat and pressure. EX: Jade, Talc, and Garnet

4 Minerals from Molten Rock Magma cools fast = small crystals Magma cools slow = large crystals Ex: Quartz, Felsdspar, Olivine

5 Minerals from Solution: Hot Water EX: Silver and Calcite

6 Minerals From Solutions: Evaporation Ex: Halite, Salts

7 Mining for Minerals Drill: What is the difference between iron and iron ore? Objective: SWBAT identify methods of mining in order to determine the most efficient method for mining certain minerals. HW: 2-2 and 2-3 due Thursday.

8 Which method to use Coal: Usually found in large amounts close to the surface. –Open Pit Gravel: Found near structurally unstable overburden (rock not wanted). Found in large quantities. –Strip mine Iron: Found deep within the ground near hard, dense rock. Can be found as veins. –Shaft Mine

9 Identifying Minerals Drill: Why do geologists use streaks of minerals to determine true color? Objective: SWBAT determine characteristics of minerals in order to identify it. HW: 2-2 and 2-3 due Thursday

10 The minerals Minerals 1 & 2 –Pyrite or Chalcopyrite Minerals A & B –Topaz or Quartz Male and Female –Magnetite or Graphite Triangle and Circle –Calcite or Halite

11 Mining for Minerals Drill: You are planning to mine minerals in an area. Some of the mineral is exposed and most of it lies close to the surface. Which type of mine would you establish Objective: SWBAT utilize resources and tests in order to determine the identity of a specimen. HW: Identifying Minerals, due Friday

12 Reviewing Minerals Drill: Name two ways minerals can form. Objective: SWBAT recall basic concepts presented in the unit. HW: Study

13 Mineral Testing Drill: List as many disadvantages to selecting the “wrong” type of mine for the mineral. Objective: SWBAT utilize test in order to gather and compare information about minerals. HW: Study; test Wednesday
