Objectives

• Prior to this activity, the students have
  demonstrated a knowledge of
• The definition of latitude and longitude
• The concept of hemisphere and how the globe is
  divided into four hemispheres.

• The Student will draw a compass rose and
  determine orientation on a map.
• The student will locate and label latitude and
  longitude coordinates on a map of the world
• The student will state the relative location of
  regions on a map.
• The student will estimate the distance between
  two points on a map by using a scale of miles.
• The student will compare maps to understand how
  the scale ratio determines the amount of detail
  on a map.

Absolute Location

• The global address of a point on the globe is
  an absolute location.
• The latitude and longitude coordinates define
  the absolute location of a point on the globe.
• The correct order for global addresses are
• North and South followed by East and West
• 60N, 120W is a correctly written address.

11

• Absolute location is the point were lines of
  latitude and longitude intersect on a grid.
• Longitude lines or Meridians run north to south
  but are read east to west.
• Latitude lines or Parallel lines run east to west
  but are measured north to south.

Step 1. Highlight the Equator Step 2. Highlight
the Prime Meridian.

• Step 5. Locate 20N, 80 W
• Locate the Northwest hemisphere. Why
• Locate 20 N, draw a line along this line to
  the Prime Meridian .
• Locate 80 W, draw a line along this line to
  the Equator
• Where the two lines intersect is 20N, 80 W
