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.

Pinpointing Location with GPS Demonstration: How GPS Works (Part 2) part of Geodesy:Activities
Shelley E Olds, EarthScope Consortium
Using string, bubble gum, and a model of a GPS station, demonstrate how GPS work to pinpoint a location on Earth.Precisely knowing a location on Earth is useful because our Earth's surface is constantly changing from earthquakes, volcanic eruptions, tectonic plate motion, landslides, and more. Thus, scientists can use positions determined with GPS to study all these Earth processes.

Nutrient Loading Module part of Project EDDIE:Teaching Materials:Modules
This module was initially developed by Castendyk, D.N., T. Meixner, and C.A. Gibson. 6 June 2015. Project EDDIE: Nutrient Loading. Project EDDIE Module 7, Version 1. Module development was supported by NSF DEB 1245707.
Estimating nutrient loads is a critical concept for students studying water quality in a variety of environmental settings. Many STEM/Environmental science students will be asked to assess the impacts of a proposed anthropogenic activities on human water resources and/or ecosystems as part of their future careers. This module engages students in exploring factors contributing to the actual loads of nitrogen that are transmitted down streams. Nitrogen is a key water quality contaminant contributing to surface water quality issues in fresh, salt, and estuarine environments. Students will utilize real-time nitrate data from the US Geological Survey to calculate nitrate loads for several locations and investigate the interplay of concentration and discharge that contributes to calculated loads.

Sustainability Metrics part of Project EDDIE:Teaching Materials:Modules
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 ...

Macro-Scale Feedbacks part of Project EDDIE:Teaching Materials:Modules
Cayelan Carey, Virginia Polytechnic Institute and State Univ; Kaitlin Farrell, University of Georgia
Environmental phenomena are often driven by multiple factors that interact across space and over time. In freshwater lakes and reservoirs worldwide, carbon cycling and subsequent carbon dioxide (CO2) and methane ...

Teleconnections part of Project EDDIE:Teaching Materials:Modules
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 ...

Climate Change Module part of Project EDDIE:Teaching Materials:Modules
This module was initially developed by O'Reilly, C.M., D.C. Richardson, and R.D. Gougis. 15 March 2017. Project EDDIE: Climate Change. Project EDDIE Module 8, Version 1.
Scientists agree that the climate is changing and that human activities are a primary cause for this change through increased emissions of CO2 and other greenhouse gases to the atmosphere. There have been times in ...

Climate Change Effects on Lake Temperatures part of Project EDDIE:Teaching Materials:Modules
Cayelan Carey, Virginia Polytechnic Institute and State Univ; Kaitlin Farrell, University of Georgia
Climate change is modifying the thermal structure of lakes around the globe. Because it is difficult to predict how lakes will respond to the many different aspects of climate change (e.g., altered temperature, ...

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.
