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.

Lesson 3: The Value of a Water Footprint (High School)
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 ...

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.

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.

Lake Modeling Module
This page was initially developed by Carey, C.C., S. Aditya, K. Subratie, and R. Figueiredo. 1 May 2016. Project EDDIE: Modeling Climate Change Effects on Lakes Using Distributed Computing. Project EDDIE Module 4, Version 1. Module development was supported by NSF DEB 1245707 and ACI 1234983. Note: An updated version of this module is available as part of the Macrosystems EDDIE project. Please visit the Climate Change Effects on Lake Temperatures module to view and download module files. We recommend using the updated Macrosystems EDDIE version of the module, as the Lake Modeling module materials have not been maintained with R code and software updates.
Lakes around the globe are experiencing the effects of climate change. In this module, students will learn how to use a lake model to explore the effects of altered weather on lakes, and then develop their own ...

Sustainability Metrics
Natalie Hunt, University of Minnesota-Twin Cities
Sustainability is a complex term applied to many different contexts in a variety of ways. As a result, it can be challenging to determine how sustainable something really is. In this module, students will use an ...

Tracking Sea Level and Paleoenvironments with Fossils
Pete Berquist, Virginia Peninsula Community College
Students use the Paleobiology Database Navigator to examine changes in sea level in southeastern North America throughout the Cretaceous, Paleogene, and Neogene Periods. They will plot the change in distribution of ...

Cross-Scale Interactions
Cayelan Carey, Virginia Polytechnic Institute and State Univ; Kaitlin Farrell, University of Georgia
Environmental phenomena are often driven by multiple factors that interact across different spatial and temporal scales. In freshwater lakes and reservoirs worldwide, phytoplankton blooms are increasing in ...

Paleoclimate and Ocean Biogeochemistry
Allison Jacobel, Middlebury College
This module guides students through an examination of how surface ocean productivity relates to global climate on glacial-interglacial timescales and how the availability of ocean nutrients can be correlated with ...

Teleconnections
Kaitlin Farrell, University of Georgia; Cayelan Carey, Virginia Polytechnic Institute and State Univ
Ecosystems can be influenced by teleconnections, in which meteorological, societal, and/or ecological phenomenon link remote regions via cause and effect relationships. Because it is difficult to predict how ...
