This lesson introduces GPS technology through a series of hands on activities. These activities are scaffolded by group discussions and a presentation. The first activity is a geo-caching exercise that requires a variety of navigation and problem solving skills. Each geo-cache presents a question or fact about GPS technology and its uses. The second activity uses Google Maps to reinforce the lessons learned in the geo-caching activity and to solidify the students understanding of the latitude-longitude coordinate system. The final activity requires students to physically model the relationship of GPS receivers and satellites in an attempt to answer the question of how many satellites a receiver must connect with to fix its 3D position.
