Unit 4: The Magic of Geophysical Inversion
Lee Slater, Rutgers University-Newark
This unit introduces the student to the concept of geophysical inversion, which is the process of estimating the geophysical properties of the subsurface from the geophysical observations. The basic mechanics of ...

Unit 2: Examining the Distribution of Mass Wasting Events
Bobak Karimi, Wilkes Community College; 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 ...

3D View from a Drone | Make a 3D Model From Your Photos
Shelley E Olds, EarthScope Consortium
Using cameras mounted to drones, students will design and construct an experiment to take enough photos to make a 3-dimensional image of an outcrop or landform in a process called structure from motion (SfM). This activity has both a hands-on component (collecting data with the drone) and a computer-based component (creating the 3-dimensional model).___________________Drones can take photos that can be analyzed later. By planning ahead to have enough overlap between photos, you take those individual photos and make a 3-dimensional image!In this activity, you guide the students to identify an outcrop or landform to study later or over repeat visits. They go through the process to plan, conduct, and analyze an investigation to help answer their science question.The Challenge: Design and conduct an experiment to take enough photos to make a 3-dimensional image of an outcrop or landform, then analyze the image and interpret the resulting 3-d image.For instance they might wish to study a hillside that has been changed from a previous forest fire. How is the hillside starting to shift after rainstorms or snows? Monitoring an area over many months can lead to discoveries about how the erosional processes happen and also provide homeowners, park rangers, planners, and others valuable information to take action to stabilize areas to prevent landslides.

Teleconnections
Kaitlin Farrell, University of Georgia; Cayelan Carey, Virginia Polytechnic Institute and State University
Ecosystems can be influenced by teleconnections, in which meteorological, societal, and/or ecological phenomenon link remote regions via cause and effect relationships. Because it is difficult to predict how ...

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, ...

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 ...

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 ...

Plate Tectonics: GPS Data, Boundary Zones, and Earthquake Hazards
Christopher Berg, Orange Coast College; Beth Pratt-Sitaula, EarthScope Consortium; Julie Elliott, Michigan State University
Students work with high precision GPS data to explore how motion near a plate boundary is distributed over a larger region than the boundary line on the map. This allows them to investigate how earthquake hazard ...

Macro-Scale Feedbacks
Cayelan Carey, Virginia Polytechnic Institute and State University; Kaitlin Farrell, University of Georgia
Environmental phenomena are often driven by multiple factors that interact across space and over time. In freshwater lakes and reservoirs worldwide, carbon cycling and subsequent carbon dioxide (CO2) and methane ...

Frequency of Large Earthquakes
Jennifer Pickering
Using the IRIS Earthquake Browser tool, students gather data to support a claim about how many large (Mw 8+) earthquakes will happen globally each year. This activity provides scaffolded experience downloading data and manipulating data within a spreadsheet.
