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 ...

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.

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.

Exploring Tectonic Motions with GPS part of EarthScope ANGLE:Educational Materials:Activities
Shelley E Olds, EarthScope Consortium
Learners study plate tectonic motions by analyzing Global Positioning System (GPS) data, represented as vectors on a map. By observing changes in vector lengths and directions, learners interpret whether regions are compressing, extending, or sliding past each other. To synthesize their findings, learners identify locations most likely to have earthquakes, and defend their choices by providing evidence based on the tectonic motions from the GPS vector and seismic hazards maps.

Base Isolation for Earthquake Resistance part of EarthScope ANGLE:Educational Materials:Activities
Larry Braile (Purdue University) and TOTLE (Teachers on the Leading Edge) Project
This document includes two activities related to earthquake base isolation. Learners explore earthquake hazards and damage to buildings by constructing model buildings and subjecting the buildings to ground vibration (shaking similar to earthquake vibrations) on a small shake table. Base isolation a powerful tool for earthquake engineering. It is meant to enable a building to survive a potentially devastating seismic impact through a proper initial design or subsequent modifications. The buildings are constructed by two- or three-person learner teams.

Earthquake Hazard Maps & Liquefaction: Alaska emphasis part of EarthScope ANGLE:Educational Materials:Activities
TOTLE (Teachers on the Leading Edge), CEETEP (Cascadia EarthScope Earthquake and Tsunami Education Program), EarthScope ANGLE, and ShakeAlert projects
Ground shaking is the primary cause of earthquake damage to man-made structures. This exercise combines three related activities on the topic of shaking-induced ground instability: a ground shaking amplification demonstration, a seismic landslides demonstration, and a liquefaction experiment. The amplitude of ground shaking is affected by the type of near-surface rocks and soil. Earthquake ground shaking can cause even gently sloping areas to slide when those same areas would be stable under normal conditions. Liquefaction is a phenomenon where water-saturated sand and silt take on the characteristics of a dense liquid during the intense ground shaking of an earthquake and deform. Includes Alaska and San Francisco examples.

Building Shaking —Variations of the BOSS Model part of EarthScope ANGLE:Educational Materials:Activities
IRIS (Incorporated Research Institutions for Seismology), FEMA (Federal Emergency Management Administration), ShakeAlert, Chris Hedeen (Oregon City High School), and ANGLE Project
Building Oscillation Seismic Simulation, or BOSS, is an opportunity for learners to explore the phenomenon of resonance for different building heights while performing a scientific experiment that employs mathematical skills. They experience how structures behave dynamically during an earthquake.

How Do We Know Where an Earthquake Originated? part of EarthScope ANGLE:Educational Materials:Activities
Jeffrey Barker (Binghamton University) & Michael Hubenthal (IRIS)
Students use real seismograms to determine the arrival times for P and S waves and use these times to determine the distance of the seismic station from the earthquake. Seismograms from three stations are provided to determine the epicenter using the S – P (S minus P) method. Because real seismograms contain some "noise" with resultant uncertainty in locating arrival times of P and S waves, this activity promotes appreciation for uncertainties in interpretation of real scientific data.

Alaska GPS Analysis of Plate Tectonics and Earthquakes part of EarthScope ANGLE:Educational Materials:Activities
Beth Pratt-Sitaula, EarthScope
This activity introduces students to high precision GPS as it is used in geoscience research. Students build "gumdrop" GPS units and study data from three Alaska GPS stations from the Plate Boundary Observatory network. They learn how Alaska's south central region is "locked and loading" as the Pacific Plate pushes into North America and builds up energy that will be released in the future in other earthquakes such as the 1964 Alaska earthquake.
