Standard 3 Objective 1: Compare rocks and minerals and describe how they are related. a) Recognize that most rocks are composed of minerals. b) Observe and describe the minerals found in rocks (e.g., shape, color, luster, texture, hardness). c) Categorize rock samples as sedimentary, metamorphic, or igneous. 3:1 Minerals Pure substances (FeSiO) Solid at room temperature Inorganic Crystal structure Naturally Occurring 3:1 Properties of Minerals Hardness Color Crystal Shape Streak Break or Cleave 3:1 Identifying Minerals http://www.lizzadromuseum.org/game/basic.ht ml Use the website to identify 3 different minerals. 3:1 Rocks Made of many different minerals. Rocks are grouped by how they are made. Minerals a classified by structure and what they are made of. 3:1 Types of Rocks Igneous- Come from cooled magma and have crystals. Sedimentary- When sediments harden this layer often contains fossils Metamorphic- When igneous or sedimentary rock gets put under a lot of heat or pressure it turns into a different type of rock. 3:1 Quiz 1. What are the characteristics of Minerals? 2. How do you find hardness? 3. How do you find streak? 4. What is the difference between cleavage and fracture in minerals? 5. What is the difference between rocks and minerals? 6. What are the 3 main types of rocks?
