Absolute Location Using GPS Technology By: Kevin A. Tholin  LaSalle High School,  South Bend, Indiana USA  June 14, 2002  Classroom sessions/estimated time: two 55-minute class sessions (1 lecture/worksheets, 1 GPS activity)  Grade level(s):  9th Grade  Purpose/rationale: Students need to be aware of the grid system and GPS technology to function successfully in today’s information-based economy.  Indiana Social Studies Academic Standard addressed:  WG 1.1: Explain the Earth’s grid system, and be able to locate places using degrees of latitude and longitude.  WG 1.3: Use locational technology in order to establish spatial relationships.  Objectives:  Students should be able to:  1. understand the difference between absolute and relative location. 2. use the standard grid system coordinate system. 3. use Global Positioning Systems in order to establish spatial relationships. Background:  Students should be aware of directions.  Materials Required:   World Geography textbook  PowerPoint presentation  Worksheets  GPS unit  Prizes for GPS activity Procedure:  Day 1: Opening Activity  As they enter the classroom, students will be given a coordinates card (e.g. A-7, D-3) for their seat location.  After all of the students are seated, explain the grid system they used to find their seat is similar to the grid system used for locating places on the globe.  PowerPoint Presentation  Teacher will lecture with the aid of a PowerPoint presentation.  Guided Practice  Teacher will use a page in the book explaining how the global grid system works.  Students will answer the questions that appear at the end of the section.  Independent Practice  Geography skilld activity worksheets  Day 2:  GPS field activity  Students will be introduced a standard, inexpensive GPS unit.  Students will be split into pairs, given one GPS unit, and a set of coordinates.  The teacher demonstrates how data is entered into the GPS unit.  Each pair of students follows the directions of the GPS unit to find the prize.  Assessment: verbal feedback, participation, worksheets, GPS activity  Adaptations/Extensions: UTM system  Interested students will be introduced to the Universal Transverse Mercator grid system.
