Presentation Transcript

  1. Monday 11/27/17 • Copy this week’s schedule into your assignment notebook. • Notebook Entry: Alfred Wegener proposed continental drift in 1912. He based his hypothesis in part on the shapes of the continents. How do you think we knew the shape of the continents in the early 1900s?

  2. Corrections: Test and Convection Lab CER • Corrections must be written on separate piece of paper. • TEST: Due by end of today • Write the question #, your new answer and where in your book or notes you found confirmation of the right answer. • Example: #5 – B. Outer Core, textbook pg. 15 • Lab CER: Due by Wednesday • Write the heading for the section you are fixing. • Rewrite the entire section by including the good parts of your first attempt with your revisions.

  3. How did we create maps before planes & satellites? • The oldest known maps are preserved on Babylonian clay tablets from about 2300 B.C. • The first whole-world maps began to appear in the early 16th century, following voyages by Columbus and others to the New World.  • Surveying is a way to collect data on the land to create a map. • Surveyors use compasses, measuring chains, and optical equipment for measuring altitudes and distances.

  4. HYPOTHESIS OF CONTINENTAL DRIFT • Proposed by Alfred Wegener in 1910 • Approximately 200 million years ago, all of the continents were combined into one super-continent called Pangea • Continents gradually drifted apart to where they are today

  5. HYPOTHESIZING • Making a possible explanation that can be investigated (studied). • Based on observation or scientific knowledge.

  6. Big Question: Are earthquakes and volcanoes related? Learning Target: I can analyze and interpret data to provide evidence of continental drift.

  7. Observations lead to questions… • Mesosaurus, an aquatic reptile whose fossil remains are only found in eastern South America and southern Africa. • If Mesosaurus had been able to swim well enough to cross the vast South Atlantic Ocean, its fossils should be on other continents. This is not the case.

  8. Fossil Evidence Step #1: Label the landmasses with their continent name (1 of them is a country, not a continent.)

  9. Fossil Evidence • Color code the fossil evidence based on the key • Cut out the landmasses. • Create a supercontinent by matching up the fossil evidence & placing the landmasses on a page of your spiral (hint: turn your spiral horizontal) • Raise your hand to have your placement checked. • Glue the landmasses into your science notebook. • Take out a piece of paper and complete the writing prompt in the sheet protector. Turn in when you are finished.

  10. Tuesday 11/28/17 Notebook Entry: One of the fossils that Wegener examined was the tropical plant Glossopteris. Fossils of this plant’s leaves and seeds have been found on Antarctica. Why would it be strange to find a tropical plant fossil in Antarctica?

  11. Fossil Evidence • Color code the fossil evidence based on the key • Cut out the landmasses. • Create a supercontinent by matching up the fossil evidence & placing the landmasses on a page of your spiral (hint: turn your spiral horizontal) • Raise your hand to have your placement checked. • Glue the landmasses into your science notebook. • Take out a piece of paper and complete the writing prompt in the sheet protector. Turn in when you are finished. If you have extra time start on the reading homework.

  12. Folded Mountains with Matching rocks Glacial Deposits

  13. Glue your world map into your science notebook by ONLY gluing the top two corners to it lifts like a flap over your supercontinent.

  14. Homework Read and do pgs. 80-81 In the Earth Structure textbook (geode on the front)
