Location of New York State

TP: “To summarize latitude and longitude coordinate system.”

New York State is always located in the:• Northern Hemisphere (latitude)• Western Hemisphere (longitude)

TP: “To summarize latitude and longitude coordinate system.”

Latitude LinesThe equator separates the Northern and Southern hemispheres.

Minimum latitude = 0°Maximum latitude = 90°N and 90°S.

TP: “To summarize latitude and longitude coordinate system.”

Longitude LinesThe prime meridian separates the Western and Eastern hemispheres.

Minimum longitude = 0°Maximum longitude = 180°

TP: “To summarize latitude and longitude coordinate system.”

The Coordinate SystemAlways written as the latitude followed by the longitude.

Example: 45°N, 75°W

Practice: Turn to pg. 4 of the ESRT. Determine the continent with the following coordinates:

20°S, 140°E =

Quick AssessmentTP: “To summarize latitude and longitude coordinate system.”

• Take out your SMART clickers, and wait for me to “start” your class

• Then, sign into my class and wait for the assessment to start

• As soon as the assessment starts, you have one (1) minute to answer the multiple choice question

Intellectual EngagementDo you think a geographic coordinate system was invented before humans began navigating the oceans or after? Explain.

-or-

How else do you think a geographic coordinate system could be useful?

Task- Identify the name of the landmass or ocean with these coordinates: (40°N, 100°W), (75°S, 100°E), and (20°N, 80°E) Student 1- Then, which hemisphere (northern or southern) has more landmass and less ocean waterStudent 2- Then, identify the major continents that are shared between the eastern and western hemispheres. Student 3- Then, identify the major continents that are shared between the northern and southern hemispheres. Flexible Group- take out your portfolio and meet me in the back of the room for a conference.

Lesson SummaryIn your tables of four, go back into your notes and consider what we have just learned today, and then…

1. Identify three (3) important concepts we learned today

2. Place those the three in order from the most important concept to least important.
