Description of the activity/assignment

This unit on Navigation begins with a brief history of navigation and maps, including building a simple compass as an introduction to the magnetic field of Earth. Division of Earth navigation units in Lat/Long and UTM are explored in detail. Topographic maps as an expression of Earth's surface are used to integrate all of the pervious topics.

Determining whether students have met the goals

There is a brief quiz at every stage of the unit (after each exercise).
