10/18/11 and 10/19/11

  1. 1. 10/19/11 B DayLEQ: How do humans use technology tostudy geologic evolution?1. What is an adaptation?2. What is one adaptation that bald eagles have tohelp them survive?3. What is natural selection?4. Give one example of natural selection.5. Copy and complete the following sentence: If two species share similar adaptations, we can assume that they (share a common ancestor/ were born on the same continent)
  2. 2. Schedule:TODAY: LAST DAY OF UNIT 1NEXT CLASS: REVIEW FOR UNIT 1 EXAMNEXT CLASS: UNIT 1 EXAM
  3. 3. Today’s LEQ: How do humans use technology to study geologic evolution?By the end of today, you should be able to…1. Compare and contrast information gathered from remote imagery and ground truthing2. Identify the different ways that sets of data are collected
  4. 4. Focus Vocabulary:42. Remote Sensing43. Ground truthing44. Urban Sprawl
  5. 5. Activating Strategy:Discovery Education: Tragedy in New Orleans STOP AND JOT:How did scientists, politicians, and the media collect information about the causes and effects of Hurricane Katrina?
  6. 6. Hurricane Katrina Satellite Images – Remote SensingBefore After Super Dome in New Orleans
  7. 7. Before AfterWhat information can you observe and infer from this photo? NEW NEW ORLEANS ORLEANS
  8. 8. What information can you observe and infer from this photo?
  9. 9. How are these two photos different?
  10. 10. You just discovered…. The two differentmethods for collecting data about geologic evolution!
  11. 11. Draw this in your notes: Collecting DataREMOTE SENSING:-collectinginformation aboutan area withoutvisiting itEx. Satellite photos
  12. 12. Observe and Infer:Let’s compare these two regions… Image 1 Image 2
  13. 13. How can remote sensing help us see…–Beach erosion (evens)–Deforestation–Forest Fire damage–Volcanic eruptions (odds)–Urban Sprawl–Ice on Earth
  14. 14. B. We can see beach erosion after a hurricane through satellite imagery (remote sensing)
  15. 15. Deforestation
  16. 16. Forest Fires!
  17. 17. July 2008 October 2008Kasatochi Volcano before and after the August 2008 eruption. An example of volcanic eruption Remote sensing!
  18. 18. Ice on Earth
  19. 19. Remote Sensing ???????
  20. 20. Draw this in your notes: Collecting DataREMOTE SENSING: GROUND TRUTHING:-collecting -collectinginformation about information about anan area without area by visiting itvisiting it Ex. Taking waterEx. Satellite photos samples
  21. 21. Remote Sensing Ground Truthing
  22. 22. PUT THESE IN YOUR T-CHART!Satellite Images Collecting soil samples Investigating buried fossils Weather StationChecking a Baby monitor Interviewing people in personAerial (airplane) photographs Taking pictures with a portable camera
  23. 23. Remote Sensing Ground Truthing-satellite images -collecting soil samples-aerial photographs -interviewing people-baby monitor -taking pictures with a-weather station portable camera -investigating buried fossils
  24. 24. What are the advantages and disadvantages of using remote sensing?Advantages Disadvantages• Can track changes of • Cannot test conditions an area over time of the environment• Do not actually have to • Cannot see detail go to the area • Cannot talk to people• Can collect data from who are there the area anytime
  25. 25. What are the advantages and disadvantages of ground truthing?Advantages Disadvantages• Test the conditions of • Can only survey a small the environment area at a time• More detail regarding • Cannot track change of the area can be the area over a long observed period of time• Verify what remote • Can only collect data sensing gathers when area is safe• Talk to people who are there
  26. 26. HOT Q: Think-Pair-ShareIt’s 2005, and Hurricane Katrina is hitting New Orleans. How could you use remote sensing and ground truthing to gather data and information about the hurricane and the damage it caused?
  27. 27. CONTEXT CLUES:1. I live in an urban area. There are big buildings, busy streets, and lots of people that always seem to be busy!2. He was so tired from school that he went straight home and fell asleep. When his mom got home, she found him sprawled across the couch with his backpack still on!2. Her things were sprawled all across the floor. Youcould barely see the carpet when you walked into herroom! Stop and Jot: Write your own definition of these words!
  28. 28. Word Study:Urban = CitySprawl = spread out; usually in a sloppy way WHAT IS URBAN SPRAWL?
  29. 29. FRAYER DIAGRAM: Urban SprawlDEFINITION: LOOKS LIKE:Cities spreading out intoareas that used to be rural(countryside)Study with: Urban Sprawl EFFECTS:
  30. 30. Urban Sprawl• http://www.youtube.com/watch?v=5qGSIqsFa _Y
  31. 31. Urban Sprawl Video1. How are satellites used to observe urban sprawl?2. What are some problems with urban sprawl identified in the video?3. What kind of information do we use to track urban sprawl? http://www.youtube.com/watch?v=5qGSIqsFa _Y
  32. 32. FRAYER DIAGRAM: VOCAB WORDDEFINITION: LOOKS LIKE:Cities spreading out into Less grassareas that used to be rural Fewer trees(countryside) More buildings More roadsStudy with: Urban Sprawl EFFECTS:
  33. 33. Las VegasMay 1973 May 2000
  34. 34. FRAYER DIAGRAM: VOCAB WORDDEFINITION: LOOKS LIKE:Cities spreading out into Less grassareas that used to be rural Fewer trees(countryside) More buildings More roadsStudy with: Urban Sprawl EFFECTS:REMOTE SENSING!
  35. 35. HOT Q: What effects would you predict as a result of urban sprawl?
  36. 36. FRAYER DIAGRAM: VOCAB WORDDEFINITION: LOOKS LIKE:Cities spreading out into Less grassareas that used to be rural Fewer trees(countryside) More buildings More roadsStudy with: Urban Sprawl EFFECTS: More cars, more buildings,REMOTE SENSING! more pollution
  37. 37. SUMMARIZER: Write a letter to the mayor of Charlotte!Your letter should:1) Describe urban sprawl2) Explain how we study urban sprawl (how do we collect the data?!)3)2000 Describe the negative effects of urban sprawl 20104) Give 2 ways that we can alleviate (ease or fix) the problem of urban sprawl in Charlotte
  38. 38. EOG PRACTICE!!!!
  39. 39. 1. What method can scientists in the UnitedStates use to monitor land use in the Amazon rainforest over time?a) Ground truthingb) Topographic mapsc) Remote sendingd) GPS
  40. 40. 3. Remote sensing is the use of imagery from space or air to describe Earth’s surface. For which of the following projects would remote sensing be most useful?a) Determining the change of elevation of a 1 square kilometer areab) Monitoring the changes in land use around a city over 5 yearsc) Determining the distance between 2 citiesd) Identifying areas where highways cross over bodies of water
  41. 41. 4. Which is best used to track the global movement of volcanic ash after an eruption?A) Ground truthingB) Satellite photographsC) Topographic mapsD) Weather balloons
  42. 42. 5. How can satellite imagery best be used after a hurricane hits the coast?A) To check nearby lake depthsB) To identify the amount of beach erosionC) To determine the location of sea turtles’ nestsD) To map topography inland of the coastal region
  43. 43. 6. Which is the best method for verifying data gathered by satellites?A) Ground truthingB) Reflectance curvesC) Satellite imageryD) Spectral analysis
