Reference materials that include maps
“Using Latitude and Longitude” worksheet
Instructional Strategy: Explain to your students the concepts of latitude and longitude and how they are
important mathematical and scientific tools to use in navigation. Using maps and a globe are helpful. Have
students complete the “Using Latitude and Longitude” worksheet. Finally, discuss why knowing latitude and
longitude is a useful and important skill when traveling into an unknown region of the Earth. How might the
explorers have used these concepts while in Antarctica?
Use the latitude and longitude grid on the map below to pinpoint each
location specified in the questions:
1) U.S. Stations in Antarctica: What is the latitude and longitude of:
2) Between what two lines of latitude must you travel to get from the tip of
South America to Antarctica? ______________________________
3) What point of longitude passes through the Ross Ice Shelf?
