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.

Exploring Tectonic Motions with GPS part of EarthScope ANGLE:Educational Materials:Activities
Learners study plate tectonic motions by analyzing Global Positioning System (GPS) data, represented as vectors on a map. By observing changes in vector lengths and directions, learners interpret whether regions are compressing, extending, or sliding past each other. To synthesize their findings, learners identify locations most likely to have earthquakes, and defend their choices by providing evidence based on the tectonic motions from the GPS vector and seismic hazards maps.

Volcano Monitoring with GPS: Westdahl Volcano Alaska part of EarthScope ANGLE:Educational Materials:Activities
Learners use graphs of GPS position data to determine how the shape of Westdahl Volcano, Alaska is changing. If the flanks of a volcano swell or recede, it is a potential indication of magma movement and changing ...

Base Isolation for Earthquake Resistance part of EarthScope ANGLE:Educational Materials:Activities
This document includes two activities related to earthquake base isolation. Learners explore earthquake hazards and damage to buildings by constructing model buildings and subjecting the buildings to ground vibration (shaking similar to earthquake vibrations) on a small shake table. Base isolation a powerful tool for earthquake engineering. It is meant to enable a building to survive a potentially devastating seismic impact through a proper initial design or subsequent modifications. The buildings are constructed by two- or three-person learner teams.

Building Shaking —Variations of the BOSS Model part of EarthScope ANGLE:Educational Materials:Activities
Building Oscillation Seismic Simulation, or BOSS, is an opportunity for learners to explore the phenomenon of resonance for different building heights while performing a scientific experiment that employs mathematical skills. They experience how structures behave dynamically during an earthquake.

Alaska GPS Analysis of Plate Tectonics and Earthquakes part of EarthScope ANGLE:Educational Materials:Activities
This activity introduces students to high precision GPS as it is used in geoscience research. Students build "gumdrop" GPS units and study data from three Alaska GPS stations from the Plate Boundary Observatory network. They learn how Alaska's south central region is "locked and loading" as the Pacific Plate pushes into North America and builds up energy that will be released in the future in other earthquakes such as the 1964 Alaska earthquake.

Earthquake Hazard Maps & Liquefaction: Alaska emphasis part of EarthScope ANGLE:Educational Materials:Activities
Ground shaking is the primary cause of earthquake damage to man-made structures. This exercise combines three related activities on the topic of shaking-induced ground instability: a ground shaking amplification demonstration, a seismic landslides demonstration, and a liquefaction experiment. The amplitude of ground shaking is affected by the type of near-surface rocks and soil. Earthquake ground shaking can cause even gently sloping areas to slide when those same areas would be stable under normal conditions. Liquefaction is a phenomenon where water-saturated sand and silt take on the characteristics of a dense liquid during the intense ground shaking of an earthquake and deform. Includes Alaska and San Francisco examples.

Seismic Slinky: Modeling P and S waves part of EarthScope ANGLE:Educational Materials:Activities
Students will produce P and S waves using a Slinky© to understand how seismic waves transfer energy as they travel through solids. All types of waves transmit energy, including beach waves, sound, light, and more. When an earthquake occurs it generates four different types of seismic waves. We will focus on two of these: Compressional-P (longitudinal) and shearing-S (transverse) "body waves." These travel through the Earth with distinct particle motion and predictable speed.

How Do We Know Where an Earthquake Originated? part of EarthScope ANGLE:Educational Materials:Activities
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.

World Map of Plate Boundaries part of EarthScope ANGLE:Educational Materials:Activities
The plate tectonics mapping activity allows students to easily begin to identify basic tectonic processes on a global scale. As students become aware of plate movements, they begin to identify patterns that set the stage for deeper understanding of a very complex topic. The activity uses a simple "Where's Waldo" approach to identify tectonic symbols on a laminated World Plate Tectonic map.

Fault Models for Teaching About Plate Tectonics part of EarthScope ANGLE:Educational Materials:Activities
This short interactive activity has learners to manipulate fault blocks to better understand different types of earthquake-generating faults in different tectonic settings--extensional, convergent, and strike-slip. Fault models aid in visualizing and understanding faulting and plate motions because the instructor and their students can manipulate a three-dimensional model for a true hands-on experience.
