Introduction to Reading GPS Time Series Plots
This lesson provides a brief introduction to GPS and provides a student activity to practice creating and reading time series plots with simplified GPS data. Students graph how a tectonic plate (and the GPS unit attached to it) has moved over a five year time period by moving a GPS model across a North-East coordinate graph.
The following files are needed to complete this activity:
- Introduction to Reading GPS Time Series Plots (v. Jun 2010) [ppt]
- Student Worksheet Reading Time Series Plots (v. Jul 2010) [pdf] [doc] ; in Spanish v. 2008 [pdf] [doc]
- Tenths of a Year to Months of a Year Scale
- Reading Time Series Plots Reference Key [pdf] ; in Spanish [pdf]
After this activity, students explore authentic GPS data; see:
