Orientation

Location

ScaleBy: Eleanor Joyce

City of Salem Schools

Objectives

•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.

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.

Orientation Location or

position relative to the points on the compass.

Cardinal Directions– North, South, East, West

Intermediate Directions- Northwest, Northeast, Southeast, Southwest

Draw a compass rose and fill in the cardinal and intermediate

directions.

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 60°N, 120°W is a correctly written address.

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. Next

Step 3. Draw and X where the two lines intersect.

Step 4. Label the hemispheres Next

Step 5. Locate 20°N, 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 20°N, 80° WNext

Scale

Ratio between a distance on a map and the corresponding distance on the earth

Representative Fraction

• a fraction or ratio between units on the map and units on the earth’s surface

• format– 1:1,000,000 OR 1/1,000,000
