Plate Tectonics: GPS Data, Boundary Zones, and Earthquake Hazards
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 ...

Exploring Tectonic Motions with GPS
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.

Learners use graphs of GPS position data to determine how the shape of Westdahl Volcano, Alaska is changing. If the flanks of a volcano swell or recede, it is a potential indication of magma movement and changing ...

Earthquake Hazard Maps & Liquefaction: Alaska emphasis
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.

How Do We Know Where an Earthquake Originated?
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
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.

Seismic Slinky: Modeling P and S waves
IRIS (Incorporated Research Institutions for Seismology)
Students will produce P and S waves using a Slinky© to understand how seismic waves transfer energy as they travel through solids. All types of waves transmit energy, including beach waves, sound, light, and more. When an earthquake occurs it generates four different types of seismic waves. We will focus on two of these: Compressional-P (longitudinal) and shearing-S (transverse) "body waves." These travel through the Earth with distinct particle motion and predictable speed.

Fault Models for Teaching About Plate Tectonics
Modified from an activity by Larry Braile (Purdue University) by TOTLE (Teachers on the Leading Edge) Project and further improved by ShakeAlert.
This short interactive activity has learners to manipulate fault blocks to better understand different types of earthquake-generating faults in different tectonic settings--extensional, convergent, and strike-slip. Fault models aid in visualizing and understanding faulting and plate motions because the instructor and their students can manipulate a three-dimensional model for a true hands-on experience.

Earthquake Machine
IRIS (Incorporated Research Institutions for Seismology) and ShakeAlert
In this activity, learners work collaboratively in small groups to explore the earthquake cycle by using a physical model. Attention is captured through several short video clips illustrating the awe-inspiring power of ground shaking resulting from earthquakes. To make students' prior knowledge explicit and activate their thinking about the topic of earthquakes, each student writes their definition of an earthquake on a sticky note. Next, through a collaborative process, small groups of students combine their individual definitions to create a consensus definition for an earthquake.

Rocks are Elastic!! Seeing is Believing
IRIS (Incorporated Research Institutions for Seismology)
This activity helps learners see the elastic properties of rocks by actually bending marble. How rocks respond to stress is a fundamental concept, critical to forming explanatory models in the geosciences (e.g., elastic rebound theory). Whereas learners are likely to have lots of experience with rocks, few will have directly experienced them behaving elastically. As a result of this "missed experience", most learners conceptualize rocks as rigid solids; a concept which generally serves students well in everyday life but impedes learning about particular geologic concepts.

World Map of Plate Boundaries
Bonnie Magura (Portland Public Schools) and Chris Hedeen (Oregon City High School)
The plate tectonics mapping activity allows students to easily begin to identify basic tectonic processes on a global scale. As students become aware of plate movements, they begin to identify patterns that set the stage for deeper understanding of a very complex topic. The activity uses a simple "Where's Waldo" approach to identify tectonic symbols on a laminated World Plate Tectonic map.

Human Wave: Modeling P and S Waves
IRIS (Incorporated Research Institutions for Seismology) and ShakeAlert
Lined up shoulder-to-shoulder, learners are the medium that P and S waves travel through in this simple, but effective demonstration. Once "performed", the principles of P and S waves will not be easily forgotten. This demonstration explores two of the four main ways energy propagates from the hypocenter of an earthquake as P and S seismic waves. The physical nature of the Human Wave demonstration makes it a highly engaging kinesthetic learning activity that helps students grasp, internalize and retain abstract information.
