  1. Volcanoes and Earthquakes!

  2. Warm Up • Why do you think magma rises? Consider an ice cube floating at the top of a glass of water

  3. Objective: • SWBAT • Describe why certain types of volcanoes are more explosive than others • Agenda: • Weather • Notes: 3 Types of Volcanoes • Volcano Articles • Closing • Homework: • None!

  4. Weather

  5. Notes: 3 Types of Volcanoes • Shield • Forms on hot spots • Broad base, small incline • Enormous height (including base below sea level) • Thin lava makes it the least explosive • EX: Mauna Loa in Hawaii • Cinder • Cone-shaped mound of ash • Smallest • Forms on sides of other volcanoes • Forms in groups • EX: Capulin in New Mexico, Mount Paricutin in Mexico • Composite (Stratovolcano) • Creates lahars (mudflows/landslides) • Forms from layers of lava (from many eruptions) • May remain dormant for long periods between eruptions • Thick lava makes it the most explosive • EX: Mount St. Helen’s in Washington, Mount Vesuvius in Italy

  6. Volcano Articles • Working individually, read the following articles and answer the accompanying questions

  7. Closing • How do volcanoes form? Please include both types of formation in your response.

  8. Warm Up • Why are certain types of volcanoes more explosive than others? • What type of volcano is the most explosive? • What type of volcano is the least explosive?

  9. Objective: • SWBAT • Explain how a volcano’s amount of activity relates to a volcano’s explosiveness • Explain how a volcano’s magma temperature relates to a volcano’s destructive potential • Agenda: • Weather • Review Volcano Article Questions and Chart • Raging Planet: Volcanoes • Closing • Homework: • None!

  10. Weather

  11. Review: Volcano Article Questions and Chart • Follow along as we review the volcano article questions and chart together • You will turn in your questions for a classwork grade and your chart for a homework grade

  12. Raging Planet: Volcanoes • While watching the Raging Planet: Volcanoes, answer the questions on your worksheet

  13. Warm Up • How does a volcano’s amount of activity relate to it’s explosiveness? • How does a volcano’s magma temperature relate to it’s destructive potential?

  14. Objective: • SWBAT • Explain what steps are important to take during an emergency and what actions should be avoided • Agenda: • Finish Raging Planet: Volcanoes • Earthquake Survival • Closing • Homework: • Extraterrestrial Volcanoes

  15. Raging Planet: Volcano • Take out your Raging Planet: Volcano Questions Sheet • Answer your questions as we finish watching the video • Follow along as Ms. McGowan reviews the answers

  16. 1999 Earthquake in Adapazari, Turkey • What kind of destruction can you see? • What kind of destruction may have occurred that you cannot see?

  17. Earthquake Survival Activity • Ms. McGowan will split you into groups of 4 • In your groups, take turns reading the Earthquake Survival Script • Then, work together to determine what actions you would take post-earthquake

  18. Closing • In the case of an emergency (where you’re trapped inside without utilities), what three steps would you take first and why?

  19. Warm Up • Take out your earthquake survival activity • What are the first two steps you would take post-earthquake? Why? • What are the last two steps you would take post-earthquake? Why?

  20. Objective: • SWBAT • Explain why scientists study seismic waves • Agenda: • Finish Earthquake Survival • Notes: Seismic Waves • Slinky Demo • Closing • Homework: • None!

  21. Earthquake Survival Activity • Ms. McGowan will split you into groups of 4 • In your groups, take turns reading the Earthquake Survival Script • Then, work together to determine what actions you would take post-earthquake

  22. 1999 Earthquake in Adapazari, Turkey • What kind of destruction can you see? • What kind of destruction may have occurred that you cannot see?

  23. Notes: Seismic Waves • Body Waves—travel through Earth’s interior • P waves • Particles move parallel to wave • Travels through anything • Fastest speed • S waves • Particles move perpendicular to wave • Only travels through solids • Medium speed • Surface Waves—travel through Earth’s surface • Slowest speed

  24. Seismic Waves Slinky Demonstration • Follow along on your Seismic Waves Demonstration Worksheet as Ms. McGowan demonstrates seismic waves with her slinky

  25. Closing • Surface waves travel the slowest. Are they still dangerous? Provide support for your answer.
