Episodic tremor and slip: The Case of the Mystery Earthquakes | Lessons on Plate Tectonics
Shelley E Olds, EarthScope Consortium
Earthquakes in western Washington and Oregon are to be expected—the region lies in the Cascadia Subduction Zone. Offshore, the Juan de Fuca tectonic plate subducts under the North American plate, from northern California to British Columbia. The region, however, also experiences exotic seismicity— Episodic Tremor and Slip (ETS).In this lesson, your students study seismic and GPS data from the region to recognize a pattern in which unusual tremors--with no surface earthquakes--coincide with jumps of GPS stations. This is ETS. Students model ductile and brittle behavior of the crust with lasagna noodles to understand how properties of materials depend on physical conditions. Finally, they assemble their knowledge of the data and models into an understanding of ETS in subduction zones and its relevance to the millions of residents in Cascadia.

Physics: Permafrost
Penny Rowe, NorthWest Research Associates
Students learn what permafrost is, the implications of permafrost thawing due to climate change, and how to calculate heat diffusion through permafrost. Student activities include watching a video about permafrost, ...

Quantum mechanics: Polar spectra
Penny Rowe, NorthWest Research Associates
Students learn about the greenhouse effect by examining a "forbidden" rovibrational band in the infrared emission spectra of Earth's atmosphere, recorded from the surface at South Pole Station. By ...

Unit 1: Exploring the Reservoirs and Pathways and Methods to Measure the Hydrologic Cycle
Jon Harvey (Fort Lewis College) and Becca Walker (Mt. San Antonio College)
How does water move throughout the Earth system? How do scientists measure the amount of water that moves through these pathways? This unit provides an alternative way for students to learn the major components of ...

Unit 2: Kilauea Hawai'i - Monday Morning Meeting at the USGS Hawai'i Volcano Observatory
Kaatje van der Hoeven Kraft, Whatcom Community College and Rachel Teasdale, California State University-Chico
How do volcanologists at the Hawaiian Volcano Observatory monitor volcanoes? In a jigsaw format, students first work in teams to learn one of the four volcano monitoring data sets (GPS, Tilt, Seismic and InSAR) and ...

Pinpointing Location with GPS Demonstration: How GPS Works (Part 2)
Shelley E Olds, EarthScope Consortium
Using string, bubble gum, and a model of a GPS station, demonstrate how GPS work to pinpoint a location on Earth.Precisely knowing a location on Earth is useful because our Earth's surface is constantly changing from earthquakes, volcanic eruptions, tectonic plate motion, landslides, and more. Thus, scientists can use positions determined with GPS to study all these Earth processes.

Unit 1: Collecting GPS Data
Karen M. Kortz (Community College of Rhode Island) Jessica J. Smay (San Jose City College)
GPS data can measure vertical and horizontal bedrock motion caused by a variety of geologic processes, such as plate movement and the changing amount of water and ice on Earth's surface. In this unit, students ...

Unit 2: Examining the Distribution of Mass Wasting Events
Bobak Karimi (Wilkes University) Stephen Hughes (University of Puerto Rico–Mayaguez)
What factors contribute to the distribution patterns of mass wasting events? In this unit, students will use a frequency-ratio method, one of the most common quantitative methods used in the statistical analysis of ...

Unit 2: Earthquakes, GPS, and Plate Movement
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 ...

Converging Tectonic Plates Demonstration
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.
