Transcript

  • 1. DATE: 10/14/11 A/B DayLEQ: How is geologic evolution related tobiologic evolution?1. What is extinction?2. A rock is dated between 300 and 500 years old. Is this an example of relative or absolute dating?3. Explain your answer from #2.4. What is an index fossil?5. What is the difference between weathering and erosion?
  • 2. CONTEXT CLUES:1. My ancestors were American Indians. Even though I do not speak the native language, I am so proud of my ancestry!2. My dog’s offspring all look exactly like my dog! Even though they are still puppies, they have the same spots!3. Over time, my opinion has evolved. At first, I thought the Mavericks were going to win, but not I think the Lakers are going to win. Stop and Jot: Write your own definition of
  • 3. Check your definitions!Ancestor: a parent or other older blood relativeOffspring: childrenEvolution: change over time
  • 4. Watch and Write! • Dance Video Question: What has happened to dancing and cell phones over time?? CELL PHONES TODAYFIRST CELL PHONE
  • 5. What is “geologicevolution”?
  • 6. Geologic Evolution
  • 7. Vocabulary Sheet:Which of our vocabulary words relate to geologic evolution?
  • 8. Remember this page?!UNIT 1: Earth’s History
  • 9. MAKE YOUR OWN BUBBLE MAP! (use your vocabulary sheet!) Geologic Evolution
  • 10. Today’s LEQ: How is geologic evolution related to biologic evolution?
  • 11. Today’s LEQ: How is geologic evolution related to biologic evolution?By the end of today, you should be able to…1. Describe how species evolve from a common ancestor over time2. Explain how survival of the fittest results in adaptations
  • 12. Focus Vocabulary37. Evolution38. Natural Selection39. Survival of the fittest40. Common Ancestor41. Adaptation

  • 17. Geologic Evolution: the ways thatthe earth changes over time Biologic Evolution: the ways that species change over timeAdaptation: Natural Selection:
  • 18. Think-Pair-Share What adaptations does this animal have that helps it survive in its environment?
  • 19. Think-Pair-ShareWhat adaptations do these animals have that help them survive in their environment?
  • 20. Think-Pair-ShareWhat adaptations do these animals have that help them survive in their environment?
  • 21. Geologic Evolution: the ways thatthe earth changes over time Biologic Evolution: the ways that species change over timeAdaptation: a Natural Selection:physical traitinherited from acommon ancestor
  • 22. COMMONANCESTOR
  • 23. FIND THE COMMON ANCESTOR!!!
  • 24. Geologic Evolution: the ways thatthe earth changes over time Biologic Evolution: the ways that species change over timeAdaptation: a Natural Selection:physical traitinherited from acommon ancestor
  • 25. HOT QUESTION #2• Fossils have shown that ancient frogs had gills similar to modern day fish. This fact can be best explained by which of the following: a. radiometric dating b. extinction c. evolution d. climate change
  • 26. You should be:Natural Selection • Thinking silently.Example • Which rabbit has a better chance of surviving in the North Pole? Why?
  • 27. All the brown rabbits dieOnly one white rabbit dies
  • 28. White rabbits have babies
  • 29. Now we have ALL white rabbits!
  • 30. PEPPERED MOTHS pre-industrializationWhich moth would be more likely to survive? WHY???
  • 31. PEPPERED MOTHS post-industrializationWhich moth would be more likely to survive? WHY???
  • 32. Geologic Evolution: the ways that the earth changes over time Biologic Evolution: the ways that species change over timeAdaptation: a Natural Selection:physical traitinherited from acommon ancestor
  • 33. Natural Selection: certain traits thathelp a species survive become morecommon over time (also called “Survivalof the Fittest”)
  • 34. What adaptations would increase survival in this environment?
  • 35. What adaptations would increase survival in this environment?
  • 36. What adaptations would increase survival in this environment?
  • 37. Pick a card, any card!• 1: Your environment temperature increases & green fur is too dark. Your species becomes extinct.• 2: A new predator has invaded your environment. This predator eats yellow species. If you have a yellow card without an X on it, sit down. If you have an X, you adapted strong leg muscles and outran the predator.• 3: There was a flood that wiped out green Xs’ food sources. You couldn’t adapt fast enough! You go extinct!• Everybody that’s left survived. You adapted to the changing environment!
  • 38. THINK-PAIR-SHARE1. What were the different adaptations?2. How did your environment change?3. In the end, which adaptations were “naturally selected”? (Which species was the fittest for the changing environment?)4. Do you think that all of the species had a common ancestor? Why or why not?
  • 39. Brain Pop—Evolution
  • 40. SUMMARIZER ACTIVITY!ForkasaurusSpoonbill PlatypusKnife Monster
  • 41. SUMMARIZER1. What adaptation allowed one animal to eat more than the other?2. Which animal would be favored (chosen) by the process of natural selection?3. How would you predict these animals to evolve over time? (Would some become extinct?)4. What change in the environment would make an animal with a different adaptation to survive? (Ex: what would have to happen in the environment in order for the knife monster to survive?)5. Do you think these animals had a commonancestor? Why or why not?
