8. TODAY’S AGENDA Tuesday 12/4 TODAY IN SCIENCE CLASS FTF Review Evidence used by Alfred Wegener - Overview Pangaea Mapping Activity 2-Column Notes on Evidence (if time) Ticket Out Homework: Open Response Essay for Quiz (due tomorrow!) SWBAT Identify 3 types of evidence used by Wegener to support his theory of continental drift. FTF Newspaper “Puzzle” Activity – Understanding Evidence Each student has 1 piece of newspaper. Carefully tear the paper into 5-8 LARGE pieces. Pass the pieces to your partner. Try to assemble the “puzzle” you were given. What evidence did you use to put the pieces of the puzzle back together? Come up with at least 3 things you used as evidence.

9. What is evidence? • Something which shows something else exists or is true. • A visible sign of something.

10. Is it Evidence?

11. Is it Evidence?

12. Wegener’s Evidence • Rock Layers • Fossils • Cynognathus • Glossopteris • Mesosaurus • Glacial Evidence (Climate) • Landforms and Mountain Ranges • Shape of continents

13. Ticket Out 3 -2 – 1 • 3 types of evidence used to support continental drift. • 2 specific examples of evidence (example: coastlines of Africa & S. America) • 1 person who came up with the theory.

14. TODAY’S AGENDA Friday 12/6 TODAY IN SCIENCE CLASS FTF Review Housekeeping – return midterms and discuss. Pangaea Mapping Activity 2-Column Notes on Evidence – to be completed after map is done Homework: Pangaea Map and Questions due Monday SWBAT Identify 3 types of evidence used by Wegener to support his theory of continental drift. FTF Name 3 types of evidence used by Wegener to support his theory of continental drift. Fossil seeds of the glossopteris plant have been found on the continents of south America and Africa. The seeds can only travel a few miles by wind. Explain how the plant could have been in both of these places. Coal deposits have been found beneath ice in Antarctica. But coal only forms in warm swamps. Use Wegener’s theory to explain how coal could be found so near the South pole.

15. Pangaea Map Activity • You will be creating a map of Pangaea based on fossil, rock, landform and glacial evidence found on present day continents. • You will examine 4 maps of modern day Earth and transfer the data from the four maps to the Pangaea map provided. • On the blank map you will create a key using the different colors to represent the different types of evidence from the maps.

17. South America Africa Let’s Do One Together EVIDENCE 1. ROCK LAYERS This diagram shows matching rock layers in Africa and South America. With a red colored pencil transfer this data to the map of Pangaea on the attached page. Also add to key. = Rock Layers

18. Mapping Alfred’s Evidence • Complete Pre Activity Questions • Map all evidence – transfer evidence from current maps to your Pangaea map. • Be sure to create the key for each piece of evidence! Your key should have 6 colors and unique pieces of evidence when complete. • Ask Mrs. Dean to show you the answer key when you are done. • Answer post-lab questions.

19. = Rock Layers

20. = Rock Layers = Cynognathus

21. = Rock Layers = Cynognathus = Glossopteris

22. = Rock Layers = Cynognathus = Glossopteris = Mesosaurus

23. = Rock Layers = Cynognathus = Glossopteris = Mesosaurus = Glaciers

24. = Rock Layers = Cynognathus = Glossopteris = Mesosaurus = Glaciers = Mountains

26. TODAY’S AGENDA Monday 12/9 TODAY IN SCIENCE CLASS New Buddies FTF Review Pangaea Mapping Activity – Finish! 2-Column Notes on Evidence Alfred Wegener Letter Assignment Homework: Rough Draft Alfred Wegener Letter SWBAT Identify 3 types of evidence used by Wegener to support his theory of continental drift. FTF (Homework Out Please) Complete Pangaea Mapping Activity!

27. Guide For Reading: What is Wegener’s theory of continental drift? • Continental drift is the hypothesis that all the continents had once been joined together in a single landmass • The continents have slowly moved apart over Earth’s surface

28. 2-Column Notesand Graphic Organizer

29. Graphic OrganizerEvidence From Landforms

31. Evidence From Landforms • Identical mountain ranges with matching

33. Figure 11: Observing: Which coastlines seem to match up like jig-saw puzzle? • The continents of Africa and South America best match up like jigsaw-puzzle pieces

34. Figure 12: Inferring: According to Wegener’s theory, what does the presence of similar mountain ranges in Africa and South America indicate? • The presence of similar mountain ranges indicates that Africa and South America were once joined.

35. Evidence From Fossils

36. Fossil • Fossil: A trace of an organism that has been preserved in rock

37. Evidence of Continental Drift

38. Evidence From Landforms • Identical mountain ranges with matching

39. How did Wegener use evidence based on fossils to support his theory that the continents had moved? • Glossopteris fossils have been found in rocks in Africa, South America, Australia, India, and Antarctica unexpectedly • Seeds could not have travel that far over the oceans to reach other continents

40. Evidence From Climate

41. Evidence From Landforms • Identical mountain ranges with matching

42. What two examples of climate change did Wegener use to support his theory of continental drift? • The Island of Spitsbergen (Arctic Ocean) has evidence of tropical plants • Deep scratches in rocks were found in South Africa, South America, India, Australia and Antarctica • These scratches support evidence of glaciers

44. Checkpoint: What were the three types of evidence Wegner used to support his theory of continental drift? • Landforms • Fossils • Climate

45. Scientists Reject Wegener’s Theory

46. Guide For Reading: Why was Alfred Wegener’s theory rejected? • Wegener could not provide an explanation of what force moved the continents. • He could not identify the cause of continental drift

47. TODAY’S AGENDA Tuesday 12/10 TODAY IN SCIENCE CLASS FTF Review Alfred Wegener Letter Assignment - Write Rough Draft Peer Editing of Letter! Homework: Final Draft Letter due Friday! SWBAT Identify 3 types of evidence used by Wegener to support his theory of continental drift. FTF (Homework Out Please) List three types of evidence used by Wegener to support his theory of continental drift? List an example of each type and where it’s found. Explain how this evidence supports Wegener’s theory of continental drift.

49. Alfred Wegener Essay • Written as letter • Written to convince colleagues of Alfred Wegener about his theory of continental drift. • Purpose is to demonstrate to me that you understand how the evidence used by Wegener supports his theory. • It is okay to use “I” and “my” in this writing because you are pretending to be Alfred Wegener. • Handwritten or typed final draft okay. Due Friday.

50. Letter Format • Introduction paragraph • 3 paragraphs • 1 Paragraph for each type of evidence • Paragraph MUST include where evidence is found • Paragraph MUST include how this evidence helps explain continental drift • Concluding Paragraph
