Frequency of Large Earthquakes part of EarthScope ANGLE:Educational Materials:Activities
Jennifer Pickering
Using the IRIS Earthquake Browser tool, students gather data to support a claim about how many large (Mw 8+) earthquakes will happen globally each year. This activity provides scaffolded experience downloading data and manipulating data within a spreadsheet.

Wind and Ocean Ecosystems part of Project EDDIE:Teaching Materials:Modules
Alanna Lecher, Lynn University; April Watson, Lynn University
Wind has a fundamental impact on ocean ecosystems. Wind drives physical processes, including current development and upwelling through Ekman transport. These physical processes, in turn, have cascading impacts on ...

Measuring Ground Motion with GPS: How GPS Works part of Geodesy:Activities
Shelley E Olds, EarthScope Consortium
With printouts of typical GPS velocity vectors found near different tectonic boundaries and models of a GPS station, demonstrate how GPS work to measure ground motion.GPS velocity vectors point in the direction that a GPS station moves as the ground it is anchored to moves. The length of a velocity vector corresponds to the rate of motion. GPS velocity vectors thus provide useful information for how Earth's crust deforms in different tectonic settings.

Measuring Plate Motion with GPS: Iceland | Lessons on Plate Tectonics part of Geodesy:Activities
Shelley E Olds, EarthScope Consortium; 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.

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.

Lake Mixing Module part of Project EDDIE:Teaching Materials:Modules
This module was initially developed by Carey, C.C., J.L. Klug, and R.L. Fuller. 1 August 2015. Project EDDIE: Dynamics of Lake Mixing. Project EDDIE Module 3, Version 1. cemast.illinoisstate.edu/data-for-students/modules/lake-mixing.shtml. Module development was supported by NSF DEB 1245707.
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 ...

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.

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 ...

Lake Ice Phenology Module part of Project EDDIE:Teaching Materials:Modules
This module was initially developed by Carey, C.C., J.L. Klug, and D.C. Richardson. 1 April 2015. Project EDDIE: Lake Ice Phenology. Project EDDIE Module 1, Version 1: cemast.illinoisstate.edu/data-for-students/modules/ice-phenology.shtml. Module development was supported by NSF DEB 1245707.
Lakes are changing worldwide due to altered climate. Many lakes that were historically frozen in the winter are now experiencing fewer days of ice cover and earlier ice-off dates. In this module, students will ...

Macro-Scale Feedbacks part of Project EDDIE:Teaching Materials:Modules
Cayelan Carey, Virginia Polytechnic Institute and State University; 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 ...
