This Where on Earth Am I? lesson plan also includes:
Almost every phone has GPS installed, but a large number of teens don't know how the technology works. An initial activity illustrates how GPS determines a location on Earth. Scholars then apply trilateration procedures to a two-dimensional representation of Earth so that they can convert the signal travel times into distances and graphically construct the position. A second activity improves the accuracy of the position by interpolating geographically.
- Research the Galileo satellite navigation system being built by Europe, which became operational at the end of 2016 and should be complete by 2020
- Discuss the limitations of the American, Russian, and Chinese GPS systems
- Each scholar needs a compass (drawing tool) and knowledge of how to properly use it
