Plate Tectonics: GPS Data, Boundary Zones, and Earthquake Hazards part of Project EDDIE:Teaching Materials:Modules
Christopher Berg, Orange Coast College; Julie Elliott, Michigan State University; Beth Pratt-Sitaula, EarthScope
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 ...

Measuring Plate Motion with GPS: Iceland | Lessons on Plate Tectonics part of Geodesy:Activities
Roger Groom, Mt. Tabor Middle School; Cate Fox-Lent, UNAVCO; Shelley E Olds, EarthScope Consortium; Nancy West, Quarter Dome Consulting; David Thesenga, Front Range Community College
This lesson teaches middle and high school students to understand the architecture of GPS—from satellites to research quality stations on the ground. This is done with physical models and a presentation. Then students learn to interpret data for the station's position through time ("time series plots"). Students represent time series data as velocity vectors and add the vectors to create a total horizontal velocity vector. They apply their skills to discover that the Mid-Atlantic Ridge is rifting Iceland. They cement and expand their understanding of GPS data with an abstraction using cars and maps. Finally, they explore GPS vectors in the context of global plate tectonics.

3D View from a Drone | Make a 3D Model From Your Photos part of Geodesy:Activities
Shelley E Olds, EarthScope Consortium; Randy Russel, UCAR Science Education Center; David Thesanga, Alexander Dawson School
Using cameras mounted to drones, students will design and construct an experiment to take enough photos to make a 3-dimensional image of an outcrop or landform in a process called structure from motion (SfM). This activity has both a hands-on component (collecting data with the drone) and a computer-based component (creating the 3-dimensional model).___________________Drones can take photos that can be analyzed later. By planning ahead to have enough overlap between photos, you take those individual photos and make a 3-dimensional image!In this activity, you guide the students to identify an outcrop or landform to study later or over repeat visits. They go through the process to plan, conduct, and analyze an investigation to help answer their science question.The Challenge: Design and conduct an experiment to take enough photos to make a 3-dimensional image of an outcrop or landform, then analyze the image and interpret the resulting 3-d image.For instance they might wish to study a hillside that has been changed from a previous forest fire. How is the hillside starting to shift after rainstorms or snows? Monitoring an area over many months can lead to discoveries about how the erosional processes happen and also provide homeowners, park rangers, planners, and others valuable information to take action to stabilize areas to prevent landslides.

Lake Mixing Module part of Project EDDIE:Teaching Materials:Modules
C.C. Carey; J.L. Klug; R.L. Fuller
Stratified lakes exhibit vertical gradients in organisms, nutrients, and oxygen, which have important implications for ecosystem structure and functioning. Mixing disrupts these gradients by redistributing these ...

Paleoclimate and Ocean Biogeochemistry part of Project EDDIE:Teaching Materials:Modules
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 part of Project EDDIE:Teaching Materials:Modules
Farrell, K.J.; Cayelan Carey, Virginia Polytechnic Institute and State University; Kaitlin Farrell, University of Georgia
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 ...

Nutrient Loading Module part of Project EDDIE:Teaching Materials:Modules
Castendyk, D.N.; T. Meixner; C.A. Gibson
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.

Cross-Scale Interactions part of Project EDDIE:Teaching Materials:Modules
Carey, C.C.; Kaitlin Farrell, University of Georgia; Cayelan Carey, Virginia Polytechnic Institute and State University
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 ...

Converging Tectonic Plates Demonstration part of Geodesy:Activities
Shelley E Olds, EarthScope Consortium; Daniel Zietlow, UNAVCO; David Thesenga, Alexander Dawson School
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.

Macro-Scale Feedbacks part of Project EDDIE:Teaching Materials:Modules
Cayelan Carey, Virginia Polytechnic Institute and State University; Kaitlin Farrell, University of Georgia; A.G. Hounshell; Carey, C.C.
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 ...
