1. Or How to Orbit the Globe

2.  There are seven continents in the world.  With your partners, lay out the blue paper.  Next, rip up the green paper in a way you feel best looks like the seven continents.  Now glue these to the blue paper in the way they would look on an atlas.

4.  North America  South America  Europe  Asia  Africa  Australia  Antarctica

5.  Atlantic  Pacific  Indian  Arctic  Southern

6.  This is a compass rose. It gives many of the directions.  The cardinal directions are north, south, east, and west.  The intermediate directions are northwest, northeast, southwest, and southeast.

8.  Butterfly – north  Tiger – northeast  Alligator – east  Pig – southeast  Bluebird – south  Kangaroo – southwest  Fish – west  Skunk - northwest

9.  A hemisphere is half of a globe.  It can be split horizontally through the Equator.  Or it can be split vertically through the Prime Meridian.

10.  What continent(s) are in the northern hemisphere?  What continent(s) are in the southern hemisphere?  What continent(s) are in the western hemisphere?  What continent(s) are in the eastern hemisphere?

12.  This is an example of a typical graph we are all familiar with.  The graph is made up of different “points” with lines that connect the points.

13.  Each point has two values:  The “X” value that runs along the horizontal “X” axis  The “Y” value that runs along the vertical “Y” axis Y axis X axis

14.  X value is always stated first  Followed by the Y value  The “origin” is the point where the 2 axes intersect with a value of (0,0) (0,0) (3,8) Y X (9,5)

15.  A point can also have negative (-) values  Negative X values are to the left of the origin (0,0)  Negative Y values are below the origin X Y (-X,+Y) (+X,-Y) (+X,+Y) (-X,-Y) (0,0)

16.  Let the X axis be the Equator.  Let the Y axis be the Prime Meridian that runs through Greenwich outside of London.  Lat/Long are the 2 grid points by which you can locate any point on earth. Y X

17.  Let each of the four quarters then be designated by North or South and East or West. N S EW

18.  The N tells us we’re north of the Equator. The S tells us we’re south of the Equator.  The E tells us that we’re east of the Prime Meridian. The W tells us that we’re west of the Prime Meridian. (N, W) (N, E) (S, W) (S, E)

19.  That means all points in North America will have a North latitude and a West longitude because it is North of the Equator and West of the Prime Meridian. (N, W) Prime Meridian

20.  What would be the latitude and longitude directions in Australia? Prime Meridian ? If you said South and East, you’re right!

21.  Latitude is the distance from the equator along the Y axis.  All points along the equator have a value of 0 degrees latitude.  North pole = 90°N  South pole = 90°S  Values are expressed in terms of degrees. Y X 90°S 90°N

22.  Each degree of latitude is divided into 60 minutes.  Each minute is divided into 60 seconds. Y X 90°S 90°N This is also true of longitude.

23.  For Example:  37°, 02’,51’’N  This is close to the latitude where you live. Y X 90°S 90°N

24.  Longitude is the distance from the prime meridian along the X axis.  All points along the prime meridian have a value of 0 degrees longitude.  The earth is divided into two parts, or hemispheres, of east and west longitude. Y X 180°W 180°E

25.  The earth is divided into 360 equal slices (meridians)  180 west and 180 east of the prime meridian Y X 180°W 180°E

26.  Our latitude and longitude might be:  37°, 03’,13’’N  76°, 29’, 45’’W Y X 90°S 90°N

27.  The origin point (0,0) is where the equator intersects the prime meridian.  (0,0) is off the western coast of Africa in the Atlantic Ocean.

28.  1. 41°N, 21°E  2. 37°N, 76°W  3. 72°S, 141°W  4. 7°S, 23°W  5. 15°N, 29°E  6. 34°S, 151°E AB C D

29.  1. B  2. A  3. C  4. C  5. B  6. D

30.  See if you can find the same latitude or longitude locations on a map!
