  1. Environmental Science Catalyst 4/14/14 • Go to class website: http://aofscience.weebly.com and scroll down to Catalysts. Complete the questions and press submit. Question: 1. How do minerals form? Place any class cash or unused emergency passes in the bin. Today is the LAST DAY I will accept these.

  2. Environmental Science Agenda 4/14/14 • Catalyst • Announcements • Minerals and Rocks Quiz on Wednesday, April 16 • Chapter 13 Packet DUE Thursday, April 17. • Period 10: Call to Action Project Details uploaded online. • Looking at Minerals and Rocks • Rocks and the Rock Cycle Discussion • Rocks Online Activity • Classwork Time • Exit Slip • Reminders

  3. Mining for . . . Cell Phones? Talk About ItIs it important to think about the sources of the minerals we use? • Large reserves of the metal tantalum are found in the Democratic Republic of the Congo, in Africa. • Tantalum jumped in value in the 1990s as high-tech devices that need tantalum, such as cell phones, became common. • There is international concern regarding the role tantalum mining has played in the extended conflict in the Congo.

  4. Objective(s) We will be able to • Explain what a mineral is. 

  5. Lesson 13.1 Minerals and Rocks Over 4000 minerals have been identified, but only 1% of these are common in Earth’s crust. Amethyst

  6. What Are Minerals? • Occur in nature • Chemically inorganic (most of the time) • Solids • Have orderly crystalline structures*** • Have definite chemical compositions (some made by one element, some are combination of compounds) Pyrite (Fool’s Gold)

  7. ***What are Crystals? • Crystals are solid, geometric forms of minerals produced by a repeating pattern of atoms.

  8. How Important Is Crystalline Structure? • Well, take a look at the following: - This is graphite - This is a diamond(pencil lead)

  9. How Important is Crystalline Structure? • They are both made from the element carbon! • The only difference is the pattern the atoms are in crystalline structure

  10. Properties of Minerals

  11. Uses for mineralsSee pictures by viewing this at http://www.schools.utah.gov/curr/Science/sciber00/7th/classify/sciber/minclas2.htm

  12. Call to Action • In small groups of your choosing, choose a community/environmental problem that you would like to tackle. • What specific steps can you do to help solve this problem?

  13. Objective(s) We will be able to • Describe how minerals form. 

  14. How do minerals form?

  15. How Diamonds Form • https://www.youtube.com/watch?v=vHPOp69SO9E

  16. Mineral Formation • Minerals can form in four ways: • Crystallization from magma or lava • Precipitation • Pressure and temperature • Production by organisms

  17. Mineral Formation: Crystallization from Magma or Lava • Crystals form as magma (deep in Earth) or lava (on Earth’s surface) from deep inside the Earth cools.

  18. Mineral Formation: Precipitation • During precipitation, liquid in a solution evaporates and leaves solids behind as crystals to form minerals.

  19. Mineral Formation: Pressure and Temperature • High temperature and pressure, may cause atoms to be rearranged.

  20. How Important is Crystalline Structure? • They are both made from the element carbon! • The only difference is the pattern the atoms are in crystalline structure • POLYMORPHS = same chemical make up, different arrangement of atoms

  21. Mineral Formation: Produced by Organisms • Outer hard structures of some organisms can become part of a mineral when they die in rock and harden.

  22. Mineral Formation Salt basins of the Sierra Nevada The Miwok people filled these basins with water from a salt spring and let it evaporate, to form salt for trading. Coral Mineral formed by living things

  23. Mineral Formation • Minerals can form in four ways: • Crystallization from magma or lava • Precipitation • Pressure and temperature • Production by organisms

  24. Where are minerals found?

  25. During Classwork Time TASK: 13.1 Questions • Stay focused on the assignments you are given. • Do the questions INDEPENDENTLY (on your own). • Keep the noise level down. • Ask THREE before you ask ME. • You may put earphones on and listen to music quietly as you do your work. (Pick a playlist and stick with it!) • You must finish a certain number of questions (depends on the person) by the end of the period.

  26. Mineral Classes Lesson 13.1 Minerals and Rocks • Minerals are classified based on their elements or compounds.

  27. Objective(s) We will be able to • Identify types of rocks and the stages of the rock cycle. 

  28. Rocks • Naturally occurring solids made up of minerals and mineral-like materials

  29. Types of Rocks • Igneous: Form when magma cools and solidifies; can be intrusive or extrusive • Sedimentary: Form when sediments cement together or when water evaporates and leaves behind minerals; can be clastic, chemical, or biochemical • Metamorphic: Form when heat or pressure changes the crystalline structure of existing rock Bryce Canyon National Park

  30. Igneous • Formed when magma cools and hardens • Can cool inside the earth (intrusive) or on its surface from volcanoes (extrusive)

  31. TYPO ALERT!!! • METAMORPHIC SHOULD BE SEDIMENTARY!!! (SWITCH THE LABELS)

  32. Sedimentary • Formed from particles of sand, shells, pebbles, and other fragments (together called sediment) • Builds up in layers and over time hardens into rock • Only type to contain fossils

  33. Metamorphic • Formed under surface of the earth from intense heat and pressure • Some have layered or banded appearance while others do not

  34. ROCK CYCLE

  35. The Rock Cycle • The rock cycle slowly changes rocks from one type to another through heating, melting, cooling, weathering, and erosion

  36. ROCK CYCLE http://youtube.com/watch?v=SRaInMDNyE8

  37. Interactive Learning! FUN!!! http://www.learner.org/interactives/rockcycle/types.html • To access the link above, go to the class website. Navigate to ENVIRONMENTAL SCIENCEChapter 13: Mineral Resources and Mining. Scroll down to “Minerals and Rocks Resources.” • Go through tutorial and take notes in your notebook. Study this material by quizzing the person next to you.

  38. Go on the class website. Click on Environmental Science  Minerals. Scroll down until you see Exit Slip. If you are talking or copying, you will not receive credit. Exit Slip Questions • Summarize the rock cycle. • Discuss the differences between the three main types of rocks.

  39. Reminders DON’T FORGET YOUR PACKET STAMPS. • Minerals and Rocks Quiz on Wednesday, April 16 • Chapter 13 Packet DUE Thursday, April 17. • Period 10: Call to Action Project Details uploaded online.
