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 ...

Topographic differencing: Earthquake along the Wasatch fault
Chelsea Scott, Arizona State University Campus Immersion
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 ...

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) ...

Plate Tectonics: GPS Data, Boundary Zones, and Earthquake Hazards
Christopher Berg, Orange Coast College; Beth Pratt-Sitaula, EarthScope Consortium; Julie Elliott, Michigan State University
Students work with high precision GPS data to explore how motion near a plate boundary is distributed over a larger region than the boundary line on the map. This allows them to investigate how earthquake hazard ...

Detecting Cascadia's changing shape with GPS | Lessons on Plate Tectonics
Shelley E Olds, EarthScope Consortium; David Thesenga, Front Range Community College
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.

3D View from a Drone | Make a 3D Model From Your Photos
Shelley E Olds, EarthScope Consortium
Using cameras mounted to drones, students will design and construct an experiment to take enough photos to make a 3-dimensional image of an outcrop or landform in a process called structure from motion (SfM). This activity has both a hands-on component (collecting data with the drone) and a computer-based component (creating the 3-dimensional model).___________________Drones can take photos that can be analyzed later. By planning ahead to have enough overlap between photos, you take those individual photos and make a 3-dimensional image!In this activity, you guide the students to identify an outcrop or landform to study later or over repeat visits. They go through the process to plan, conduct, and analyze an investigation to help answer their science question.The Challenge: Design and conduct an experiment to take enough photos to make a 3-dimensional image of an outcrop or landform, then analyze the image and interpret the resulting 3-d image.For instance they might wish to study a hillside that has been changed from a previous forest fire. How is the hillside starting to shift after rainstorms or snows? Monitoring an area over many months can lead to discoveries about how the erosional processes happen and also provide homeowners, park rangers, planners, and others valuable information to take action to stabilize areas to prevent landslides.

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 1: Introduction to Flooding
Venkatesh Merwade, Purdue University-Main Campus
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 2: Examining the Distribution of Mass Wasting Events
Bobak Karimi, Wilkes Community College; Stephen Hughes, University of Puerto Rico-Mayaguez
What factors contribute to the distribution patterns of mass wasting events? In this unit, students will use a frequency-ratio method, one of the most common quantitative methods used in the statistical analysis of ...

Measuring Plate Motion with GPS: Iceland | Lessons on Plate Tectonics
Shelley E Olds, EarthScope Consortium; David Thesenga, Front Range Community College
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.
