E: How do we distinguish between rocks and minerals? A: Anticipation Guide, Rocks Vs. Minerals. T: •Preview vocabulary: Mineral, inorganic, crystals, rock while reading text pages 268-270. •Show video Earth Science In Action: Minerals. •Have students fill in Focus Questions as they view the video. Discuss after the video. •Put samples on each table group, “Rock or mineral.” “Why?” Discuss. •Revisit Anticipations Guide, correcting all False statements. S: Explain one way rocks and minerals are similar and one way they are different? Before Rocks vs. Minerals Anticipation Guide After T F 1. Minerals are made of rocks. T F T F 2. Coal is a mineral. T F T F T F T F 3. Minerals are always made from melted rock inside the Earth. 4. The particles in a specific mineral are always the same. T F T F 5. All minerals have a crystalline structure. T F How do we distinguish between rocks and minerals? Mineral Inorganic Inorganic, solid materials found in nature, made of like particles. Not formed by plants or animals. Rocks Two or more minerals combined. Crystals An orderly, repeating pattern of atoms. What is a Mineral? • Naturally occurring • Inorganic • Characteristics have constant chemical composition • Distinctive physical properties • Crystalline structure • Formed from magma or water What is a Rock • A rock is a naturally occurring aggregate of minerals and/or other rock fragments. • Rocks are classified based on their method of formation. How do we distinguish between rocks and minerals? Rocks Minerals Rocks don’t always look the same throughout Rocks are made up of 2 or more minerals Minerals always look the same throughout (homogenous) Minerals are NOT made of rocks Video: “Earth Science in Action: Minerals” Rock or Mineral? • Look the same throughout • Mineral Rock or Mineral? Apatite Mineral Rock or Mineral? Gneiss Rock Rock or Mineral? • Don’t always look the same • Rock Rock or Mineral? Calcite Mineral Rock or Mineral? Gypsum mineral Rock or Mineral? • Has a crystalline structure • Mineral Rock or Mineral? Conglomerate Rock Rock or Mineral? Fluorite Mineral Rock or Mineral? Schist Rock Rock or Mineral? • Made up of two or more minerals • Rock Rock or Mineral? Rock Shale Rock or Mineral? Diamond Mineral Rock or Mineral? Sandstone rock Rock or Mineral?
