Exemplary Teaching Activities
Beginning in 2011, On the Cutting Edge began a process to review the extensive collection of activities submitted by workshop participants and members of the geoscience community. With the transition of the On the Cutting Edge program into NAGT the review process is now being used to broadly review online teaching activities relevant to NAGT's community of Earth educators. Through this review processes activities are scored on 5 elements: scientific veracity; alignment of goals, activity, and assessment; pedagogical effectiveness; robustness; and completeness of the description. The activities that score very highly in these areas become part of the Cutting Edge Exemplary Collection and are featured below.

Topographic differencing: Earthquake along the Wasatch fault part of Teaching Activities
Chelsea Scott, Arizona State University at the Tempe Campus
After a big earthquake happens people ask, 'Where did the earthquake occur? How big was it? What type of fault was activated?' We designed an undergraduate laboratory exercise in which students learn how ...

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

Unit 2: Earthquakes, GPS, and Plate Movement part of Measuring the Earth with GPS
Karen M. Kortz (Community College of Rhode Island)
Jessica J. Smay (San Jose City College)
GPS data can measure bedrock motion in response to deformation of the ground near plate boundaries because of plate tectonics. In this module, students will learn how to read GPS data to interpret how the bedrock ...

Lesson 1: Water Resources and Water Footprints (Middle School) part of Teaching Activities
Kai Olson-Sawyer, GRACE Communications Foundation
This lesson helps students understand why Earth is considered the "water planet." Students analyze how much of Earth's water is available for humans to use for life-sustaining purposes, and they ...

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.

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.
