  1. Chapter 2 Mapping Our World 9/12/2011

  2. Mapping Cartoon

  3. Safari • Place these 5 words in your grid: • 1). Lion • 2). Giraffe • 3). Elephant • 4). Zebra • 5). Crocodile

  4. Find Your Location http://www.youtube.com/watch?v=BIakZtDmMgo

  5. Cartoon

  6. Latitude VS Longitude Latitude Longitude • Parallel Lines to the Equator • (00 latitude) • Used to locate points North and South of the equator • 0-900 • Run East and West of Prime Meridian • (00 longitude) • Used to locate points East and West. • 0-1800

  7. Latitude VS Longitude Cont… Latitude Longitude • Degree • Minute • 60 in every degree • Seconds • 60 in every minute • Completely Parallel Lines • Divided into Degrees, Minutes, and Seconds. • Semicircles • Pole to Pole • Converge at Poles • Diverge at Equator

  8. Time Zones • 15 Degrees Longitude • Doesn’t separate main cities/places • International Date Line

  9. 41° 17' 19" N / 78° 41' 20" W39° 29' 15" N / 121° 13' 25" W Can You Do It?

  10. Contour Lines: Introductory Lab 9/14/2011

  11. Cartoon

  12. Background • Models built after Mount Capulin • Volcano in New Mexico • National Monument • Cinder-Cone

  13. What you need to do today • 1). Get your supplies • 2). Complete Drawing Your Map: Filling Box up every centimeter (cm) with blue water. • 3). Clean-up • 4). Start Answering the 3 Questions

  14. Reflective writing time:What is A Contour Line? Write down everything you know about a contour line without your notes, book, or frayer models

  15. Contour Line Discussion and Map construction9/15/2011 1). Students will understand what a contour line is. 2). Students will understand when and how to use a depression contour. 3). Students will be able to draw contour lines. 4). Students will be able to interpret contour lines and build a 3D replica.

  16. Cartoons:

  17. Contour Lines When Do You Draw Them? What should they look like? • On Topographic Maps • Equal Elevation • Should not intersect/cross • Constant Interval Between Them • Contour Interval

  18. Contour lines can tell us…. Flat vs. Steep Gradient • What do contour lines look if an area is flat? • What do contour lines look like if an area is steep? • We can use labeled contour lines to calculate gradient. • Change in elevation between a and b/Distance between a and b

  19. Could you tell that your volcano model had a concave top? • Why or Why Not? • How could we fix this? • Depression contours • Hachures

  20. Should Your Maps All Look The Same? • Why or Why Not? • What could have caused them to look so differently?

  21. Map Buildinghttp://www.mytopo.com/maps/index.cfm?search_string=Colorado 1). Receive your topographic map. 2). Discuss with group 3). Create a paper drawing of what it should look like 4). Build Your Model 5). Clean-up

  22. Cartography lab: Day 2 9/16/2011 *Students will draw accurate contour lines and label them accordingly. *Students will use these lines to calculate contour interval and gradient. *Students will assign appropriate latitude and longitude coordinates.

  23. Cartoon:

  24. Quick Review • Get out a half sheet of paper • Answer these quick questions: • 1). What is a contour line? • 2). What is a depression contour? • 3). How can you tell a depression contour apart from a normal contour line? • 4). What is a contour interval?

  25. Today • 1). Draw Contour Lines • 2). Draw Depression Contour Lines • 3). Calculate Contour Interval • 4). Draw Scale Markings (Distance Measurements) • 5). Calculate Gradient

  26. The Electromagnetic Spectrum9/19/2011 1). Students will understand the concepts of wavelength and frequency. 2). Students will understand the relationship between wavelength and frequency. 3). Students will understand the basic components of the electromagnetic spectrum.

  27. Cartoon

  28. Cartoon:

  29. Energy Moves In Waves!! Waves Move…Particles Do Not • Types of Waves: • EMS (Electromagnetic Spectrum) • Radio-Gamma • Low-High Energy

  30. Wavelength and frequency Wavelength Frequency • When the wave repeats itself • Crest to Crest • Trough to Trough • Speed at which waves repeat themselves • How many in a second • Inversely related to wavelength.

  31. Technology GPS Sonar and Satellites • Uses 24 satellites • Transmits microwaves • Sonar: Sound Waves • Landsat Satellite: • Visible Light and Infrared • Movement of plates, rivers, earthquakes, and pollution. • Topex/Poseidon Satellite: • Maps of ocean floors
