  1. Unit 2: Geologic events 7th Grade IB Science

  2. U2: Geologic Events

  3. U2: AHA Connections • Bell Work • Set up AHA Connections pages on pgs. 22-23 of your notebook. • The title is: U2: AHA Connections. NO DATE • Record the following question in the light bulb: • How do people cope with things beyond their control? • Add these 3 questions in to the same area of pgs. 22-23: • What evidence supports continental drift? • Why did scientists question the continental drift hypothesis? • Which coastlines might once have been joined together?

  4. U2:Trigger Activity Sept. 6, 2011 • Objective: You will create 2 puzzles (one with small pieces and one with large pieces). • Put the title and date on pgs. 24-25 in your notebook. • Using 2 pieces of notebook paper, draw a simple picture. • Cut one picture into large puzzle pieces. • Cut the other picture into small puzzle pieces.

  5. U2:Trigger Activity Sept. 6, 2011 • Write a hypothesis in your notebook on pg. 25 about which puzzle will go back together with less trouble. “If I put together the puzzle with…then I will be able to get all the pieces to fit.” • Put pieces together. • Write a statement after your hypothesis to explain if your hypothesis was supported or not and why.

  6. U2:Trigger Activity Sept. 6, 2011 • Homework: • Look at a map of the globe and answer the following question on pg. 24 of your notebook: Which coastlines might once have been joined together? • Answer in a STATEMENT not a paragraph. • What evidence from today’s activity helped you answer this question?

  7. U2: The Continental Drift Hypothesis 9-7-11, 9-8-11 • Climate Clues • Read pg. 188 and take BRIEF notes on pg. 2 in your foldable.

  8. U2: The Continental Drift Hypothesis, 9-7-11, 9-8-11 • Fossil Clues • Read pg. 189 and take BRIEF notes on pg. 4 of your foldable.

  9. U2: The Continental Drift Hypothesis, 9-8-11 • Rock Clues • Read pg. 190 and take BRIEF notes on pg. 3 of your foldable.

  10. U2: The Continental Drift Hypothesis, 9-9-11 • Read pg. 191 and take BRIEF notes over the section: WHAT WAS MISSING? Take notes on pg. 5 of your foldable.

  11. Amoeba People http://www.youtube.com/watch?v=T1-cES1Ekto Pangaea’s Moving Farther Apart Again http://www.youtube.com/watch?v=gyT8Xs6Ab-k&feature=related BBC http://www.youtube.com/watch?v=ryrXAGY1dmE&feature=related

  12. How old is the Atlantic Ocean, 9-14-11 • Copy the mini lab from pg. 197 onto pg. 31 in your notebook. • Choose a partner. • Work through the lab together. • Analyze and Conclude about the age of the Atlantic http://www.mysciencebox.org/node/579 http://geography.about.com/od/physicalgeography/a/magnetic.htm

  16. Types of Mountains 10-4 (NB44-45) • Folded Mountains • Examples: Rocky Mountains, The Alps • Created by compression at convergent boundaries http://www.youtube.com/watch?v=jVyBsUgD7Gk&feature=results_main&playnext=1&list=PL957C73D6B68723E3 • Fault-Block Mountains • Example: Basin and Range Province in western and southwestern U.S. • Created by tension at divergent boundaries – crust pulls apart to form a fault and large blocks of crust slide up or down http://www.youtube.com/watch?v=x_WYpKNfsnY&feature=related

  17. Types of Mountains 10-4 (NB44-45) • Uplifted Mountains • Example: Sierra Nevada Mountains • Volcanic Mountains • Examples: Mt. St. Helens, Hawaiian Islands • Formed by sitting over a hotspot or by subduction of an oceanic plate http://www.youtube.com/watch?v=Bf4iJvrAv-M

  18. Transform Faults • Occurs when plates at a divergent boundary slide horizontally to each other, perpendicular to the ridge/rift • http://www.bing.com/videos/search?q=transform+fault&view=detail&mid=9052C44400F3A614F8499052C44400F3A614F849&first=0&FORM=LKVR

  19. Fault Zones • Occur when plates slide past each other, shearing and causing smaller faults to form perpendicular to the main fault

  20. As you read through chapter 9, write questions on sticky notes (front table and back counter). • Imagine yourself teaching either earthquakes or volcanoes. What do you think is important for students to know? (Use this to guide your question writing). • Do you have any project ideas for this chapter that could help answer the BIG IDEA question (see your AHA Connections pages for Geologic Events)?

  21. Types of Faults 10-17-11 • Strike-Slip Fault • Forms at a Transform boundary (like the boundary between the Pacific Plate and the North American Plate, which has formed the San Andreas Fault Line) • http://www.youtube.com/watch?v=MrrLJ4vXHCs

  22. Types of Faults 10-17-11 • Normal Fault • Forms at a divergent boundary when two plates (or blocks of crust) are pulled apart and one slides down the other • http://www.youtube.com/watch?v=tJDnfT1pqhQ&NR=1 • What type landform can a normal fault cause?

  23. Types of Faults 10-17-11 • Reverse Fault • Forms at a convergent plate boundary when two plates compress and one plate gets pushed up slightly • http://www.youtube.com/watch?v=4b81nXSVA34&feature=related

  24. Types of Faults 10-17-11 • http://www.youtube.com/watch?v=kakc3OAfuxw&NR=1 • Which type of fault caused the Japan 2011 earthquake 80 miles off the east coast of the islands? Why do you think that? • Think-Write-Pair-Square

  25. Comparing Earthquakes 10-18-11 • How are responses of people in other nations different than and similar to the responses of people in our nation? • Learning from Chile’s Mega Quake http://player.discoveryeducation.com/index.cfm?guidAssetId=3e15863b-efe8-4c0c-a30d-14d030828777 • Kobe Earthquake 1995 http://player.discoveryeducation.com/index.cfm?guidAssetId=742594a7-a776-4486-9be2-1d8eaa789f0b

  26. Comparing Earthquakes 10-18-11 • Subduction Earthquakes http://player.discoveryeducation.com/index.cfm?guidAssetId=5d4bb3e6-5766-4f9b-be3e-431fb50313b0 Haiti Earthquake http://player.discoveryeducation.com/index.cfm?guidAssetId=946ab25a-c19c-4017-b980-633d30980183

  27. Seismic Waves and Mercalli Scale • P-Waves – Primary waves that hit the surface first • http://www.youtube.com/watch?v=2rYjlVPU9U4&feature=related • S-Waves – Secondary waves that hit the surface second • http://www.youtube.com/watch?v=en4HptC0mQ4&feature=related • http://www.youtube.com/watch?v=7NqmHtIjCJ0&feature=related

  28. Seismic Waves and Mercalli Scale • Love Waves – a transverse wave that is confined to the Earth’s surface • http://www.youtube.com/watch?v=t7wJu0Kts7w&feature=related • Rayleigh Waves – a wave transmitted from epicenter that is confined to the surface • http://www.youtube.com/watch?v=6cuEqyYIr24&feature=related • http://www.youtube.com/watch?v=BXFb5-GAgZU&feature=related • http://www.youtube.com/watch?v=r4gnO0tSXYk&NR=1

  29. Seismic Waves and Mercalli Scale • Modified Mercalli Scale • I, II, III, IV, V, VI, VII, VIII, IX, X, XI, XII • Measures the damage to HUMAN structures Richter Scale Modified Mercalli
