Unit 4: Groundwater, GPS, and Water Resources part of Measuring the Earth with GPS
Karen M. Kortz (Community College of Rhode Island) Jessica J. Smay (San Jose City College)
GPS data can measure ground elevation change in response to the changing amount of groundwater in valleys and snow cover in mountains. In this module, students will learn how to read GPS data to interpret how the ...

Topographic differencing: Earthquake along the Wasatch fault part of Teaching Activities
Chelsea Scott, Arizona State University at the Tempe Campus
After a big earthquake happens people ask, 'Where did the earthquake occur? How big was it? What type of fault was activated?' We designed an undergraduate laboratory exercise in which students learn how ...

Unit 3: What's in YOUR watershed? part of Eyes on the Hydrosphere: Tracking Water Resources
Jonathan Harvey, Fort Lewis College, and Becca Walker, Mt. San Antonio College
In this unit, students investigate water resources of their own area or another area of personal interest, which typically gets them very excited. They apply their knowledge from Units 1 and 2 to identify the water ...

Measuring Plate Motion with GPS: Iceland | Lessons on Plate Tectonics part of Geodesy:Activities
Shelley E Olds, EarthScope Consortium
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.

Unit 1: Monitoring Volcanic Activity at Mount St. Helens part of Monitoring Volcanoes and Communicating Risks
Rachel Teasdale (California State University-Chico) and Kaatje van der Hoeven Kraft (Whatcom Community College)
How can data from an impending volcanic dome-building event be used to forecast the hazard to a surrounding community? In this activity, students will examine geodetic data (GPS and lidar) and seismic data in a ...

Unit 5: Societal Implications of Climate Change: Stakeholder Report part of Understanding Our Changing Climate
Bruce Douglas, Indiana University-Bloomington; Susan Kaspari, Central Washington University
Sea-level rise due to the melting of glaciers and ice sheets and ocean thermal expansion has significant societal and economic consequences. In this final unit, students prepare a summary of the impacts of sea ...

Converging Tectonic Plates Demonstration part of Geodesy:Activities
Shelley E Olds, EarthScope Consortium
During this demo, participants use springs and a map of the Pacific Northwest with GPS vectors to investigate the stresses and surface expression of subduction zones, specifically the Juan de Fuca plate diving beneath the North American plate.

Unit 2: Earthquakes, GPS, and Plate Movement part of Measuring the Earth with GPS
Karen M. Kortz (Community College of Rhode Island) Jessica J. Smay (San Jose City College)
GPS data can measure bedrock motion in response to deformation of the ground near plate boundaries because of plate tectonics. In this module, students will learn how to read GPS data to interpret how the bedrock ...

Unit 2: Global Sea-Level Response to Temperature Changes: Temperature and Altimetry Data part of Understanding Our Changing Climate
Bruce Douglas, Indiana University-Bloomington; Susan Kaspari, Central Washington University
What is the contribution of seawater thermal expansion to recent sea-level rise? In this unit, students create time-series graphs of global averaged sea surface temperature anomaly (SSTA) data spanning 1880–2017 ...

Measuring Ground Motion with GPS: How GPS Works part of Geodesy:Activities
Shelley E Olds, EarthScope Consortium
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.
