1. Do Now I want you to think about the following prompts for two minutes. What was your favorite gift of the holiday season? Why was this your favorite? Did you get anything that you already have? Did you get anything that was just an upgrade of something you already have? What brand cell phone do you have? How often do you get a new phone? What does your phone cost? What makes your cell phone work?

2. Do Now (continued) Now, in your notebook, write continuously for 3 minutes about the same prompts, answering the following questions. What gifts did you get for Christmas / Hanukkah / Kwanzaa? What was your favorite gift of the holiday season? Why was this your favorite? Did you get anything that you already have? Did you get anything that was just an upgrade of something you already have? What did these gifts cost? What are these gifts made of? Where were they made? What brand cell phone do you have? How often do you get a new phone? What does your phone cost? What makes your cell phone work?

11. Key Concept #3 The Main Physical Properties Used to Identify Minerals Color a poor indicator minerals can be multiple colors many minerals are the same color

12. Key Concept #3 The Main Physical Properties Used to Identify Minerals Streak the powder form of a mineralmore reliable than color

13. Key Concept #3 The Main Physical Properties Used to Identify Minerals Luster how light reflects off a mineral metallicnon-metallic looks like a metal looks earthy, waxy, greasy or brilliant

14. Key Concept #3 Cleavage The Main Physical Properties Used to Identify Minerals the mineral breaks in a predictable pattern because of its arrangement of atoms

22. Key Concept #3 Fracture The Main Physical Properties Used to Identify Minerals the mineral breaks randomly

23. Key Concept #3 Hardness The Main Physical Properties Used to Identify Minerals resistance to being scratched It is NOT the same as breaking! For example: You can break glass easily with steel. However, steel will not scratch glass.
