March 24 th /28 th Unit 7: Earth Science Principled Objective(s): 1.SWBAT identify minerals based on their physical properties. Relevance: The Earth is made up of many different materials, including minerals. Scientists use specific criteria and physical properties to identify different minerals. Do Now: Four-Square Do Now MATERIALS NEEDED: 1.Pencil 2.Unit 7, Day 6 Packet 3.Agenda

The processes that form one rock into another type of rock is called what? What process must happen in order to change a sedimentary rock into a metamorphic rock? Explain the way in which a metamorphic rock would change into an igneous rock. What is the last step in the formation of a sedimentary rock? Four-Square Do Now 5 min Silently fill in the table on your daily packet Rock Cycle Extreme heat and pressure Melting into magma and then cooling into igneous rock. Cementation

BrainPop Video Let’s take a look at this BrainPop video about identifying minerals. Try to remember all the physical properties scientists use to identify minerals (and examples of them!)

Minerals A mineral is a naturally formed solid substance with a crystallized structure, not formed from living things. 10 min

Physical Properties Take out your McGraw-Hill textbook and turn to page 94. As a class, we will read through this chapter on minerals. One scholar will read each paragraph and we will popcorn around the room until we are finished. While we are reading, you should be filling in the blanks on your guided notes. 10 min

Physical Properties of Minerals PropertyDefinitionProcess/Characteristics Color The color of the mineral. List all the colors present in that mineral. Streak The color of a mineral in powder form. Not necessarily the color of the mineral itself. Rub it across a streak plate. Luster The way a mineral reflects or absorbs light. Identify how the light reflects off a mineral – metallic, non-metallic, dull, etc. Hardness The resistance of a mineral to being scratched. Mohs’ hardness scale

Mohs’ Hardness Scale Which mineral could scratch calcite but be scratched by apatite?

Taboo With your elbow partner, you will use the table in your guided notes to identify the mineral based on the hardness, luster, streak, and/or color. Voice Level 1 Partner guessing the mineral should write the name of the mineral in their guided notes. Thumbs up when the first partner is done guessing. 15 min

Practice RoundLazurite {Try not to let your partner guess on the first try} Say: This mineral has a non- metallic luster. This mineral has a bright blue streak and its color is a brilliant blue. This mineral has a hardness of min
