Lake Ice Phenology Module
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 ...

Unit 2: Geophysical Properties of the Subsurface
Lee Slater, Rutgers University-Newark
Archie (1950) defined the term petrophysics to describe the study of the physics of rocks, particularly with respect to the fluids they contain. Although originally focused on geophysical exploration, petrophysics ...

Paleoclimate and Ocean Biogeochemistry
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 ...

Wind and Ocean Ecosystems
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 ...

Visualizing Relationships with Data: Exploring plate boundaries with Earthquakes, Volcanoes, and GPS Data in the Western U.S. & Alaska | Lessons on Plate Tectonics
Shelley E Olds, EarthScope Consortium; Becca Walker, Mt San Antonio College
Learners use the GPS Velocity Viewer, or the included map packet to visualize relationships between earthquakes, volcanoes, and plate boundaries as a jigsaw activity.

Climate Change Effects on Lake Temperatures
Cayelan Carey, Virginia Polytechnic Institute and State University; Kaitlin Farrell, University of Georgia; Mary Lofton, Virginia Polytechnic Institute and State University
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, ...

Lake Modeling Module
Cayelan Carey, Virginia Polytechnic Institute and State University
Lakes around the globe are experiencing the effects of climate change. In this module, students will learn how to use a lake model to explore the effects of altered weather on lakes, and then develop their own ...

Measuring Ground Motion with GPS: How GPS Works
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.

Unit 3: Field Geophysical Measurements
Lee Slater, Rutgers University-Newark
Near-surface geophysical measurements are performed by moving sensors across the earth's surface. Active geophysical sensors transmit a signal into the earth and record a returned signal that contains ...

Exploring California's Plate Motion and Deformation with GPS | Lessons on Plate Tectonics
Shelley E Olds, EarthScope Consortium; David Thesenga, Front Range Community College
Students analyze data to study the motion of the Pacific and North American tectonic plates. From GPS data, students detect relative motion between the plates in the San Andreas fault zone--with and without earthquakes. To get to that discovery, they use physical models to understand the architecture of GPS, from satellites to sensitive stations on the ground. They learn to interpret time series data collected by stations (in the spreading regime of Iceland), to cast data as horizontal north-south and east-west vectors, and to add those vectors head-to-tail.Students then apply their skills and understanding to data in the context of the strike-slip fault zone of a transform plate boundary. They interpret time series plots from an earthquake in Parkfield, CA to calculate the resulting slip on the fault and (optionally) the earthquake's magnitude.
