Exploring California's Plate Motion and Deformation with GPS | Lessons on Plate Tectonics part of Activities
Students analyze data to study the motion of the Pacific and North American tectonic plates. From GPS data, students detect relative motion between the plates in the San Andreas fault zone--with and without earthquakes. To get to that discovery, they use physical models to understand the architecture of GPS, from satellites to sensitive stations on the ground. They learn to interpret time series data collected by stations (in the spreading regime of Iceland), to cast data as horizontal north-south and east-west vectors, and to add those vectors head-to-tail.Students then apply their skills and understanding to data in the context of the strike-slip fault zone of a transform plate boundary. They interpret time series plots from an earthquake in Parkfield, CA to calculate the resulting slip on the fault and (optionally) the earthquake's magnitude.

Volcano Monitoring with GPS: Westdahl Volcano Alaska part of EarthScope ANGLE:Educational Materials:Activities
Learners use graphs of GPS position data to determine how the shape of Westdahl Volcano, Alaska is changing. If the flanks of a volcano swell or recede, it is a potential indication of magma movement and changing ...

Alaska GPS Analysis of Plate Tectonics and Earthquakes part of EarthScope ANGLE:Educational Materials:Activities
This activity introduces students to high precision GPS as it is used in geoscience research. Students build "gumdrop" GPS units and study data from three Alaska GPS stations from the Plate Boundary Observatory network. They learn how Alaska's south central region is "locked and loading" as the Pacific Plate pushes into North America and builds up energy that will be released in the future in other earthquakes such as the 1964 Alaska earthquake.

Exploring Tectonic Motions with GPS part of EarthScope ANGLE:Educational Materials:Activities
Using a map showing the horizontal velocities of GPS stations in the Plate Boundary Observatory and other GPS networks in Alaska and Western United States, students are able to describe the motions in different regions by interpreting the vectors resulting from long-term high-precision Global Positioning System (GPS) data.

Measuring Plate Motion with GPS: Iceland | Lessons on Plate Tectonics part of Activities
This lesson teaches middle and high school students to understand the architecture of GPS—from satellites to research quality stations on the ground. This is done with physical models and a presentation. Then students learn to interpret data for the station's position through time ("time series plots"). Students represent time series data as velocity vectors and add the vectors to create a total horizontal velocity vector. They apply their skills to discover that the Mid-Atlantic Ridge is rifting Iceland. They cement and expand their understanding of GPS data with an abstraction using cars and maps. Finally, they explore GPS vectors in the context of global plate tectonics.

Measuring Ground Motion with GPS: How GPS Works part of Activities
With printouts of typical GPS velocity vectors found near different tectonic boundaries and models of a GPS station, demonstrate how GPS work to measure ground motion.GPS velocity vectors point in the direction that a GPS station moves as the ground it is anchored to moves. The length of a velocity vector corresponds to the rate of motion. GPS velocity vectors thus provide useful information for how Earth's crust deforms in different tectonic settings.
