Using Predictive Demos in an Oceanography 100 Online Course
Al Trujillo, Palomar College
Physical demonstrations of physical processes are a key component of most geoscience courses and serve to help deepen student understanding of complex processes. How does one do this for online courses? I filmed ...

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.

Reasons for the Seasons
Declan De Paor, Old Dominion University; Steve Whitmeyer, James Madison University
Reasons for the seasons (RFTS for short) is an interactive learning resource that leverages the popular Google Earth virtual globe. It is designed to help students and members of the public visualize and understand ...

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.

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
Learners use the GPS Velocity Viewer, or the included map packet to visualize relationships between earthquakes, volcanoes, and plate boundaries as a jigsaw activity.

Lecture Tutorials for Introductory Physical Geology
Eileen Herrstrom, University of Illinois at Urbana-Champaign
These activities take place in a lecture setting and require ~5-10 minutes to complete. Students apply lecture topics directly to answer questions, interpret maps and photographs, perform calculations, and plot ...

Exploring Marine Sediments Using Google Earth
Kristen St. John, James Madison University
This exercise uses empirical data and Google Earth to explore the surficial distribution of marine sediments in the modern ocean. Over 2500 sites are plotted with access to original data. We recommend first ...

Melting ice cubes
Mirjam Glessmer, University of Bergen
Explore how melting of ice cubes floating in water is influenced by the salinity of the water. Important oceanographic concepts like density and density driven currents are visualized and can be discussed on the ...

Tracking Sea Level and Paleoenvironments with Fossils
Pete Berquist, Virginia Peninsula Community College
Students use the Paleobiology Database Navigator to examine changes in sea level in southeastern North America throughout the Cretaceous, Paleogene, and Neogene Periods. They will plot the change in distribution of ...

Measuring Plate Motion with GPS: Iceland | Lessons on Plate Tectonics
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.
