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.

Detecting Cascadia's changing shape with GPS | Lessons on Plate Tectonics part of Geodesy:Activities
Shelley E Olds, EarthScope Consortium
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.

Let's Look Inside the Earth part of Teaching Activities
David Zelenka
Students will analyze USGS seismology data in the classroom using spreadsheets and scatter plots to look for patterns and structure in the Earth's crust. Before analyzing data, students will learn about the ...

Seafloor Spreading: Bathymetry, Anomalies, and Sediments part of Introductory Courses:Activities
Eileen Herrstrom, University of Illinois at Urbana-Champaign
This activity takes place in a laboratory setting and requires ~1.5-2 hours to complete. Students study the bathymetry of the South Atlantic, use magnetic reversals to interpret marine magnetic anomalies, and ...

Reconnaissance stratigraphy and mapping of the Frying Pan Gulch, MT part of Cutting Edge:Enhance Your Teaching:Teaching with Online Field Experiences:Activities
Sinan Akciz, California State University-Fullerton
Students are required to create a reconnaissance geologic map and report for a small area (approximately 0.5 sq. mile) Frying Pan Gulch just NW of Dillon, Montana. This project is designed to make students familiar ...

Virtual Geological Mapping Field Trip - Glens of Tekoa, New Zealand part of Teaching Activities
Travis Horton, University of Canterbury; Katherine Pedley
Geological mapping involves the observation, recording, presentation and interpretation of field data, all fundamental skills required by practicing geologists. This virtual geological mapping exercise enables ...

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.

Episodic tremor and slip: The Case of the Mystery Earthquakes | Lessons on Plate Tectonics part of Geodesy:Activities
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.

Plate Tectonics: GPS Data, Boundary Zones, and Earthquake Hazards part of Project EDDIE:Teaching Materials:Modules
Christopher Berg, Orange Coast College; Beth Pratt-Sitaula, EarthScope; 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 ...

Lecture Tutorials for Introductory Physical Geology part of Introductory Courses:Activities
Eileen Herrstrom, University of Illinois at Urbana-Champaign
These activities take place in a lecture setting and require ~5-10 minutes to complete. Students apply lecture topics directly to answer questions, interpret maps and photographs, perform calculations, and plot ...
