Purpose (In Own Words)

Agenda

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

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

Lines of Latitude and Longitude

• Tropic of Cancer = 45N• Halfway to North Pole

• Tropic of Capricorn = 45S• Halfway to South Pole

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

Lines of Latitude and Longitude

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)

Other Information

• Measured in Degrees, Minutes, Seconds

• DMS• GPS uses decimals

• 360 degrees total – longitude (180W, 180E)

• 180 degrees total – latitude (90N, 90S)

Practicing Longitude and Latitude

• Find Hannah Game• Going on a Trip• Quiz yourself

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.

Agenda

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

Time Zones (15 degree incrm.)

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
