Students will learn how to perform basic skills using a Garmin GPS unit; mark waypoints, navigate to a waypoint, use the compass and 'go to' functions to estimate distance to a pre-programmed point, change GPS data to find hidden locations. Students will work in teams and help each other as they learn new GPS skills and gain a working understanding of georeferenced data, using clues and team work to solve problems, and how objects are oriented in space.
