Reading Time Series Plots
Used this activity? Share your experiences and modifications
This activity provides a brief introduction to GPS and provides a student activity to practice creating and reading time series plots with simplified GPS data and with authentic GPS data from Iceland.
This activity is taught within a suite of activities on the application of GPS and Geodesy to study plate tectonics and other sciences. While I teach this to faculty of undergraduate and upper-secondary students, this activity has been taught in introductory geology.
Skills and concepts that students must have mastered
reading and creating a simple graph, concept of tectonic plates, basic algebraic skills,
How the activity is situated in the course
after tectonic plates, used as a technique to have students discover that the plates are moving
Content/concepts goals for this activity
- Explain the components of GPS data.
- Determine velocity vectors from GPS time series plots.
- Describe how GPS vectors relate to plate motion / deformation.
- Identify uses of GPS in applications in addition to driving and hiking.

Description of the activity/assignment
This activity 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. Students practice these skills by analyzing GPS time series from two GPS stations in Iceland.
Adaptations that allow this activity to be successful in an online
Need to really transform to an online environment. I did have one participant draw the vectors on an online map of Iceland - however, only one person gets to do this, so I'd like to figure out other techniques for this.

Determining whether students have met the goals
After practicing reading two component GPS data, students check their understanding with a series of graphs to determine direction of motion. The final section has the students plot vectors onto a map.
