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.
