Karst Hydrogeology: A virtual field introduction using Google Earth and GIS
Rachel Bosch, Northern Kentucky University
Students will have the opportunity to select and virtually explore the hydrogeology and geomorphology of a karst landscape using Google Earth, lidar data-sourced DEM(s) and geologic maps, and GIS software (QGIS) ...

Getting started with Structure from Motion (SfM) photogrammetry
Beth Pratt-Sitaula, EarthScope Consortium
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 ...

Indiana River Meanders Mapping Exercise
Emily Zawacki, Arizona State University at the Tempe Campus
In Indiana, major rivers and their tributaries cross much of the state. These rivers can produce significant hazards related to flooding and erosion, which threaten nearby residents and infrastructure. Rivers are ...

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 1: Climate Change and Sea Level: Who Are the Stakeholders?
Bruce Douglas, Indiana University-Bloomington; Susan Kaspari, Central Washington University
How are rising sea levels already influencing different regions? This unit offers case study examples for a coastal developing country (Bangladesh), a major coastal urban area (southern California), and an island ...

Converging Tectonic Plates Demonstration
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 4: Measuring Ice Mass Changes: Vertical Bedrock GPS
Bruce Douglas, Indiana University-Bloomington; Susan Kaspari, Central Washington University
This unit shows how GPS records of bedrock surface elevation may be used to monitor snow and ice loading/unloading on decadal and annual time scales. Students calculate secular trends in the GPS time series and ...

Visualizing Relationships with Data: Exploring plate boundaries with Earthquakes, Volcanoes, and GPS Data in the Western U.S. & Alaska | Lessons on Plate Tectonics
Shelley E Olds, EarthScope Consortium
Learners use the GPS Velocity Viewer, or the included map packet to visualize relationships between earthquakes, volcanoes, and plate boundaries as a jigsaw activity.

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

Exploring California's Plate Motion and Deformation with GPS | Lessons on Plate Tectonics
Shelley E Olds, EarthScope Consortium
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.
