2  Distortion: Changing the shape of something  Hemisphere: One-half the earth  Cartographer: Someone who is skilled at drawing maps  Map Scale: Compares the distance on a map to the distance of a place on earth.  Satellite: An object in space that goes around the earth or other body.

3  Title  Scale  Legend/Key  Compass Rose

4  How do you make a round surface flat without changing it?  To make a map, the rounded surface of the globe must be changed, or distorted, to show it as a flat surface.  There are many types of maps.  Some maps can show one type of feature without distorting it, but other features must be distorted instead.  Each of these maps has a different purpose; each has some distortion.

5  Can you flatten an eggshell without changing it?  When a cartographer makes a map, it is like trying to make the round eggshell flat.  When you look at a map of the world, you see it all there on a flat surface.  Yet when you look at a globe, you can only see half of the world at a time.

6  There is no way for a cartographer to draw a flat map of the earth and show everything the same way it looks on the globe.  The cartographer must decide what to distort, or change, and what features not to distort.  Half of the earth is called a hemisphere.  If you cut an orange in half, you would have two halves or hemispheres.  There can be a Northern Hemisphere, Southern Hemisphere, Eastern Hemisphere and Western Hemisphere.  Since this cannot be done, a cartographer must decide what to distort or change.

7  Size  Shape

8  Cartographers will distort different features on a map for different reasons.  To make the map useful for a particular reason, they try to keep that one feature from being distorted.  For example, if you want to compare the shapes of the continents, you want a map that shows these shapes as they really are.  The cartographer would then draw a map that does not distort the shapes.
