Getting started with Structure from Motion (SfM) photogrammetry
Beth Pratt-Sitaula, EarthScope
Structure from Motion (SfM) photogrammetry method uses overlapping images to create a 3D point cloud of an object or landscape. It can be applied to everything from fault scarps to landslides to topography. This ...

Unit 1: Introduction to Flooding
Venkatesh Merwade, Purdue University (vmerwade@purdue.edu) James McNamara, Boise State University (jmcnamar@boisestate.edu)
Do geoscientists understand the meaning of floods and their role within the broader context of ecological and societal impacts? In this unit, students are introduced to the concept of flooding and the mechanisms ...

Unit 3: Global Sea-Level Response to Ice Mass Loss: GRACE and InSAR data
Bruce Douglas, Indiana University-Bloomington; Susan Kaspari, Central Washington University
What is the contribution of melting ice sheets compared to other sources of sea-level rise? How much is the sea level projected to increase during the twenty-first century? In this unit, students will use Gravity ...

Episodic tremor and slip: The Case of the Mystery Earthquakes | Lessons on Plate Tectonics
Shelley E Olds, EarthScope Consortium
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.

Unit 5: Societal Implications of Climate Change: Stakeholder Report
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 ...

Unit 1: Exploring the Reservoirs and Pathways and Methods to Measure the Hydrologic Cycle
Jon Harvey (Fort Lewis College) and Becca Walker (Mt. San Antonio College)
How does water move throughout the Earth system? How do scientists measure the amount of water that moves through these pathways? This unit provides an alternative way for students to learn the major components of ...

Unit 3: What's in YOUR watershed?
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 Ground Motion with GPS: How GPS Works
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.

Unit 2: Kilauea Hawai'i - Monday Morning Meeting at the USGS Hawai'i Volcano Observatory
Kaatje van der Hoeven Kraft, Whatcom Community College and Rachel Teasdale, California State University-Chico
How do volcanologists at the Hawaiian Volcano Observatory monitor volcanoes? In a jigsaw format, students first work in teams to learn one of the four volcano monitoring data sets (GPS, Tilt, Seismic and InSAR) and ...

Unit 2: Monitoring surface and groundwater supply in central and western US
Jonathan Harvey (Fort Lewis College) and Becca Walker (Mt San Antonio College)
In Unit 2, students learn how the techniques for water budgeting (covered in Unit 1) can be used to monitor both groundwater (High Plains Aquifer) and surface water (western mountain watershed) systems. Students ...
