Base Isolation for Earthquake Resistance
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.

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.

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.

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.

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.

Alaska Plate Tectonics & Geohazards Presentation
ANGLE Project
This lecture and associated animations give a basic introduction to plate tectonics and associated earthquakes and volcanoes, using Alaska as the case study site. A similar lecture featuring the USA's Pacific Northwest region is available from the Cascadia EarthScope Earthquake and Tsunami Education Program (CEETEP)

Earthquake Basics Presentation
Robert Butler (ANGLE Project)
This lecture and associated animations give a strong introduction to earthquakes--including earthquake waves, magnitude, intensity, USArray seismic data, and resulting hazards such as landslides, liquefaction, and building failure. It also includes some information on seismically resilient building design. It uses Alaska as the case study site. A similar lecture featuring the USA's Pacific Northwest region is available from the Cascadia EarthScope Earthquake and Tsunami Education Program (CEETEP)

Alaskan Volcanoes & Hazards Presentation
This lecture and associated animations give a basic introduction to Alaskan volcanoes, volcanic hazards, and volcano monitoring.

Building Shaking —Variations of the BOSS Model
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.
