Detecting Cascadia's changing shape with GPS | Lessons on Plate Tectonics part of Geodesy:Activities
Research-grade Global Positioning Systems (GPS) allow students to deduce that Earth's crust is changing shape in measurable ways. From data gathered by EarthScope's Plate Boundary Observatory, students discover that the Pacific Northwest of the United States and coastal British Columbia — the Cascadia region - are geologically active: tectonic plates move and collide; they shift and buckle; continental crust deforms; regions warp; rocks crumple, bend, and will break.

Measuring Plate Motion with GPS: Iceland | Lessons on Plate Tectonics part of Geodesy: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 Geodesy: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.

Exploring California's Plate Motion and Deformation with GPS | Lessons on Plate Tectonics part of Geodesy: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.

Episodic tremor and slip: The Case of the Mystery Earthquakes | Lessons on Plate Tectonics part of Geodesy:Activities
Earthquakes in western Washington and Oregon are to be expected—the region lies in the Cascadia Subduction Zone. Offshore, the Juan de Fuca tectonic plate subducts under the North American plate, from northern California to British Columbia. The region, however, also experiences exotic seismicity— Episodic Tremor and Slip (ETS).In this lesson, your students study seismic and GPS data from the region to recognize a pattern in which unusual tremors--with no surface earthquakes--coincide with jumps of GPS stations. This is ETS. Students model ductile and brittle behavior of the crust with lasagna noodles to understand how properties of materials depend on physical conditions. Finally, they assemble their knowledge of the data and models into an understanding of ETS in subduction zones and its relevance to the millions of residents in Cascadia.

Tsunami Early Warning Demonstration part of Geodesy:Activities
This hands-on demonstration illustrates how instruments can be used to warn people of a tsunami. The same principles can be applied to earthquake early warning. With an older audience, this is a demonstration that can be used to start a conversation. With a younger audience, this activity is a game.

Pinpointing Location with GPS Demonstration: How GPS Works (Part 2) part of Geodesy:Activities
Using string, bubble gum, and a model of a GPS station, demonstrate how GPS work to pinpoint a location on Earth.Precisely knowing a location on Earth is useful because our Earth's surface is constantly changing from earthquakes, volcanic eruptions, tectonic plate motion, landslides, and more. Thus, scientists can use positions determined with GPS to study all these Earth processes.

Earthquake Early Warning Demonstration part of Geodesy:Activities
This hands-on demonstration illustrates how GPS instruments can be used in earthquake early warning systems to alert people of impending shaking. The same principles can be applied to other types of early warning systems (such as tsunami) or to early warning systems using a different type of geophysical sensor (such as a seismometer instead of a GPS).This demo is essentially a game that works best with a large audience (ideally over 30 people) in an auditorium. A few people are selected to be either surgeons, GPS stations, or a warning siren, with everyone else forming an earthquake "wave."

Science with Flubber: Glacial Isostasy part of Geodesy:Activities
Using two sets of flubber, one representing the Earth and one representing a glacier, demonstrate how the crust sinks and rebounds to the weight of a glacier, and how this motion can be measured using GPS.Flubber is a rubbery elastic substance, a non-Newtonian elasco-plastic fluid, that flows under gravity, but breaks when under high stress. Flubber is useful for demonstrating a wide range of Earth and glacier processes.

Introduction to Graphing GPS data | Lessons on Plate Tectonics part of Geodesy:Activities
This activity emphasizes making graphs—in order to make interpreting graphs easier. Students graph data measuring how GPS stations move north or south and east or west. They begin by graphing fictitious data and progress to graphing data from several stations in the western United States. Eventually they graph north-south vs. east-west motion of a station in order to see that another purpose of plotting data is to make maps. They also develop intuition about vectors.
