Objective: In this lesson you will plot the location of your ship on your map, determine what direction you are headed in and what city you will dock in (port-of-call).

Materials:

 

Instructions:
Part One: Determine direction in which you are headed.

  1. Using the latitude and longitude data you recorded, plot both the Current Position AND Previous Position #4 on your desk-size map.  Make sure to label each position (use "C" for current and "P4" for previous).
  2. What direction is the ship heading? (north, south, east, west, northwest, etc.) HINT: The ship moves FROM its Previous Position TO its Current Position. Record the direction on Handout #3 .
  3. Discuss with your class or group the observations you can make about how the ship is moving.

Part Two: Determine what city or port-of-call you are headed towards

  1. On your smaller desk-sized map draw a straight line, using your ruler, that starts at the Previous Position (marked "P4") and goes through the Current Position (marked "C").  Extend the line past the Current Position mark until the line intersects or hits land.
  2. Assuming that the ship will sail in a straight line the place where your line intersects the land is the port where your ship will dock or the port-of-call.  Circle this area on your map and label it "port-of-call".  Record the name of the country that your destination is located in on Handout #3.
  3. In many cases, the place where your line intersects the land will not correspond to a particular shipping port.  To determine exactly which port or city your ship is headed towards you will need to search a database of world shipping port.  Follow the link to the Port Focus.   At that site you can select the country that your ship will dock in.
  4. After selecting a country you will get a list of all of the major shipping ports that are located in that country.  Look at your map again and see if one of the cities near the area you circled is listed in the database list of results.  Select the port which is closest to the area you originally circled.  Record the name of this city on Handout #3 on the lined labeled port-of-call .
  5. OPTIONAL: You can click on the link to the port-of-call from the World Sea Port web site to learn more about your destination.
