  10. Agenda • Bellwork – review Map Elements • HW: Check, Review Map Elements • Notes: Latitude and Longitude • HW: Battleship • Quiz Friday for Honors, Monday for Standard

  11. Latitude • Imaginary lines drawing circles around the Earth, parallel to the Equator • Called Parallels • Measure North and South of the Equator • Equator = 0 degrees • North Pole = 90N • South Pole = 90S

  12. Lines of Latitude and Longitude Tropic of Cancer = 45N Halfway to North Pole Tropic of Capricorn = 45S Halfway to South Pole

  13. Longitude • Imaginary lines called Meridians • Run longways down from the poles • Measure West and East of Prime Meridian • Prime Meridian (0 degrees) in Greenwich, England • 180 degrees = opposite side, called International Date Line

  14. Lines of Latitude and Longitude

  15. Writing Latitude and Longitude Absolute Location: coordinates (39N,180E) as example Latitude is first always, longitude is second NS are Latitude (north/south of Equator) E/W are Longitude (East/West of Prime Meridian)

  16. Other Information Measured in Degrees, Minutes, Seconds DMS GPS uses decimals 360 degrees total – longitude (180W, 180E) 180 degrees total – latitude (90N, 90S)

  17. Practicing Longitude and Latitude Find Hannah Game Going on a Trip Quiz yourself

  18. Bellwork • Get out Battleship Game Piece • Do you have 10 coordinates marked and labeled? • You cannot play the game if you don’t have those coordinates marked.

  19. Agenda • Bellwork – Prep Game Piece • Notes: Time Zones • Review Latitude and Longitude • Battleship • HW: Study for Quiz 1.1!!

  20. Time Zones (15 degree incrm.)

  21. Time Zones • GMT = Greenwich Mean Time • Based on the time at the Prime Meridian • Every time zone builds out from there • Central Time Zone is -6 from GMT • Based on 15 degree increments • 15 X 24 hr = 360 degrees
