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.

Activity 10: Feedback Loops Applied part of Teaching Activities
Cameron Weiner, Middlebury College
Students apply the vocabulary and concepts from the Activity 9: Feedback Loop Introduction to assess and create earth science feedback loops with the LOOPY online modeling program. (Optional) The students then ...

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 ...

Lesson 1: Water Resources and Water Footprints (Middle School) part of Teaching Activities
Kai Olson-Sawyer, GRACE Communications Foundation
This lesson helps students understand why Earth is considered the "water planet." Students analyze how much of Earth's water is available for humans to use for life-sustaining purposes, and they ...

Engaging With Earthquake Hazard and Risk part of EarthScope ANGLE:Educational Materials:Activities
Jennifer Pickering
This introductory activity engages learners in the study of earthquake hazards and the risk these hazards pose to humans in the communities in which we live. Learners will compare three maps of Anchorage, AK, depicting spatial information related to seismic hazards to generate questions about the factors that influence shaking intensity and damage to the built environment during earthquakes.

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.

Visualizing Relationships with Data: Exploring plate boundaries with Earthquakes, Volcanoes, and GPS Data in the Western U.S. & Alaska | Lessons on Plate Tectonics part of Geodesy:Activities
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.

Lesson 3: The Value of a Water Footprint (Middle School) part of Teaching Activities
Kai Olson-Sawyer, GRACE Communications Foundation
Session 1 of this lesson begins with a quick activity to get students thinking about their direct and virtual water use. It introduces a few new ideas for virtual water use that may surprise students, including the ...

Exploring California's Plate Motion and Deformation with GPS | Lessons on Plate Tectonics part of Geodesy:Activities
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.
