  15. VIDEO NOTES TOPIC:WHAT IS BIODIVERSITY IN WHAT WAYS IS BIODIVERSITY IMPORTANT? WHY IS BIODIVERSITY IMPORTANT?

  16. READING CHECK QUIZ ABSOLUTE SILENCE NO MOVEMENT STAY AT SEAT NO NOICE OR TAPING NO TURNING AROUND WHEN DONE TURN TEST OVER AND WAIT SILENTLY

  17. VIDEO NOTES: Biodiversity is vital to life on Earth. Biodiversity is the number of different species and the variety within species. High biodiversity is important for healthy sustainable ecosystems. Biodiversity acts as a buffer against change. Biodiversity is rapidly decreasing on Earth.

  18. READING CHECK QUIZ ABSOLUTE SILENCE NO MOVEMENT STAY AT SEAT NO NOICE OR TAPING NO TURNING AROUND WHEN DONE TURN TEST OVER AND WAIT SILENTLY

  19. READING CHECK QUIZWEEK 27: 374-384 1. TRUE OR FALSE? Evolution is scientific law that tells us how living things descended from earlier organisms. 2. TRUE OR FALSE? Fossils, similarities in DNA and protein structures, similar body structures and patterns of ealy development all provide evidence that organisms changed over time.

  20. PM: READING CHECK QUIZWEEK 27: 374-384 1. TRUE OR FALSE? Fossils, similarities in DNA and protein structures, similar body structures and patterns of ealy development all provide evidence that organisms changed over time. 2. TRUE OR FALSE? Evolution is scientific law that tells us how living things descended from earlier organisms.

  23. TOPIC: EXTINCTION Extinction-VIDEO NOTES What are causes of extinction?

  24. Scavenger Word Hunt: (Start on 374) Look through new Lesson 11 and find these vocabulary terms, and write their definitions in your ISN. 1.Extinction 2. Variation 3. Natural Selection 4. Homologous Structures

  25. LAST Day Remediation TODAY • * If you are finished remediating please work silently on your VOCABULARY SHEET • VOICE LEVEL: Low/Whisper • Movement: Only with Permission • Help: RAISE HAND • NO CELL PHONES ALLOWED.

  26. Examine picture and explain how this is an example of our learning goal 2. Describe the ways in which genetic variation (through many generations) and environmental factors contribute to evolution by natural selection and diversity 3. 1.

  27. Class Work • 1. Read the article “When Fish first walked” and then answer two questions: • Why did whiter peppered moth change into black one? • Why do you think black peppered moth could change back into white? After completed we will watch video about Peppered Moths.

  28. Round Table-Partner Work • From the just read article answer the handout pages 1+2 and circle answers with the eraser marker on the transparent sleeve. • Raise your hand when done you will be given a key to check your answers. • Voice Level: Low/Whisper • Movement: NO (Ask for help/pencil/sharpener) HELP: Raise Your Hand PHONES NOT ALLOWED. TIMER: 8 MIN

  29. Class Work Reviewed • Fish that developed the ability to walk, or later live out of water is one example of natural selection. 1. Give your own example of how another species has adapted via natural selection. 2. How you think one trait could be both advantageous and disadvantageous? (hint: think BATFISH Book 374/375) 3. What is Theory of Evolution? (Darwin Theory Book 384/385) Essential QUESTION Batfish Pearson

  30. GRADING ISN NOTEBOOKSQUIET VOICES –VERY LOW HAVE YOUR NOTEBOOK READY-STAPLED/GLUED HANDOUTS BRING IT TO TEACHER FOR GRADE WHEN CALLED DO YOUR HOMEWORK WHEN DONE-374-384

  31. Darwin Hypothesized that species change over many generations and become better adapted to new conditions. Darwin proposed that over a long time natural selection can lead to change. Helpful variations may accumulate in species and unfavorable disappear. Charles DarwinCLASS NOTES

  32. WHAT IS EVOLUTION? WATCH VIDEO WRITE 3 FACTS IN ISN SHARE WITH PARTNER TAKE TURNS. Mechanisms-of-evolution-TWIG

  33. WHAT IS EVIDENCE FOR EVOLUTION? WATCH VIDEO WRITE 3 FACTS IN ISN SHARE WITH PARTNER TAKE TURNS. Evolution-evidence-TWIG

  34. Darwin’s Theory ( Charles Darwin Studied Finches at Galapagos Islands) Galápagos Finches The structure of each bird’s beak is an adaptation to the type of food the bird eats. Match each finch to the type of food you think it eats. TURN TO PAGE 387

  35. HAPPY Monday BE PREPARED: Pick up NOTEBOOK at door. SIT DOWN Have PEN/Pencil Agenda: Evolution: Animal Adaptations T. Trimpe 2008 http://sciencespot.net/

  36. FIRST READ PAGE 382 During Bellringer: VOICE LEVEL: LOW -WHISPER MOVEMENT: WITH PERMISSION ONLY HELP RAISE HAND, THEN COME TO MY DESK ONE AT A TIME PHONES: NO TIMER: 8 MIN • 1. What evidence supports evolution? (recall video we watched on Thursday + look at pages 380/381) • 2. Bats and birds have wings, what kind of evidence might show they are related? • 3. Compare bones of a bird’s wing and dolphin flipper. (page 382)

  37. Answers FIRST READ PAGE 382 During Bellringer: VOICE LEVEL: LOW -WHISPER MOVEMENT: WITH PERMISSION HELP RAISE HAND, THEN COME TO MY DESK ONE AT A TIME PHONES: NO • 1. Evidence: Fossils, similar DNA, Similar body structures =homologous structures. • 2. Similar bones pointing to a common ancestor but DNA will confirm they are related. • 3. Both bird’s wing and dolphin’s flipper have same bones in somewhat different shapes.

  38. Evidence of Evolution (TURN TO PAGE 382-AND COLOR IN FIGURE 3) Homologous Structures The bones in a bird’s wing, a dolphin’s flipper, and a dog’s leg have similar structures. Which bones in the dog's leg match those in the flipper and which match those in the wing?

  39. Evidence of Evolution • The Fossil Record • Geographic Distribution of Living Things-similar environments have similar types of organisms • Homologous Body Structures • Similarities in Early Development

  40. Homologous Structures • Homologous Structures-SIMILAR structures that related species have inherited from common ancestor and also have different mature forms in different organisms, but develop from the same embryonic tissue. (Turn to page 383 and look at figure 4)

  41. Similarities in Early Development

  42. Other Evidence for Evolution • Vestigial organs-organs that serve no useful function in an organism • i.e.) appendix, miniature legs, arms Bird Brain Evolution

  43. TURN TO SHOULDER PARNER TAKE TURNS: 1. In your own words, describe what YOU think Adaptation means (recall Batfish adaptations)2. Then watchSM: Animal ADAPTATIONvideo and write 3 new things you have now learned.

  44. FIRST READ PAGE 385+388 During Bellringer: VOICE LEVEL: LOW -WHISPER MOVEMENT: WITH PERMISSION ONLY HELP RAISE HAND, THEN COME TO MY DESK ONE AT A TIME PHONES: NO TIMER: 8 MIN • 1. What is main difference between a “Hypothesis” and Scientific Theory? (Pages 385/388) • 2. Sexual reproduction causes variation in species. How does this affect survival of species? • 3. What role “adaptation” plays in “natural selection”? (page 390)

  45. ANSWERS During Bellringer: VOICE LEVEL: LOW -WHISPER MOVEMENT: WITH PERMISSION ONLY HELP RAISE HAND, THEN COME TO MY DESK ONE AT A TIME PHONES: NO TIMER: 8 MIN • 1. Both hypothesis and scientific theory are based on observation but scientific theory is based on tested and verified hypothesis. (Pages 385/388) • 2. Species that has no variation might eventually become extinct. • 3. Adaptation to environment is a factor that affects survival likelihood of species. (page 390)

  46. Graded Partner Work Lab: Adaptation & Natural Selection Procedures: During Partner Work: VOICE LEVEL: LOW -WHISPER MOVEMENT: WITH PERMISSION ONLY HELP RAISE HAND PHONES: NO • Sign both of your names on the handout; • Read handout together with your shoulder mate, then take turns giving examples -3 example each student –total 6 animal examples. • Highlight the definition of Adaptation and copy it in your ISN.

  47. Read Page 390: Complete figure 5 Factors That Affect Natural Selection What are the factors of natural selection that affect a group of sea turtles over time?

  48. TURN TO SHOULDER PARNER TAKE TURNS: 1. In your own words, describe what YOU think NATURAL SELECTION means…
