Indiana River Meanders Mapping Exercise part of Teach the Earth:Teaching Activities
In Indiana, major rivers and their tributaries cross much of the state. These rivers can produce significant hazards related to flooding and erosion, which threaten nearby residents and infrastructure. Rivers are ...

Using Carbon Isotopes in Astrobiology: Origin of Life and beyond part of Teach the Earth:Teaching Activities
Carbon isotopes are used in many different ways by scientists to reconstruct Earth's past. For example, we can use carbon isotopes to determine when life first evolved on Earth, and to learn more about what ...

Student perspectives on climate discussions from the UN Conference of Parties (COP) via audio narrative part of Teach the Earth:Teaching Activities
This assignment provides students a storytelling structure that allows for their own voice and creativity to be applied. This is accomplished through the selection of an audience for a recorded voicemail and the ...

OGGM-Edu Glaciology Lab 1: What Makes a Glacier? part of Teach the Earth:Teaching Activities
This is a three-part class or lab activity that challenges students to define what a glacier is, how it differs from other parts of the cryosphere (such as sea ice), and what kinds of glaciers there are in the ...

Episodic tremor and slip: The Case of the Mystery Earthquakes | Lessons on Plate Tectonics part of Geodesy:Activities
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.

Visualizing Relationships with Data: Exploring plate boundaries with Earthquakes, Volcanoes, and GPS Data in the Western U.S. & Alaska | Lessons on Plate Tectonics part of Geodesy:Activities
Learners use the UNAVCO GPS Velocity Viewer, or the included map packet to visualize relationships between earthquakes, volcanoes, and plate boundaries as a jigsaw activity.

3D View from a Drone | Make a 3D Model From Your Photos part of Geodesy:Activities
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.

Detecting Cascadia's changing shape with GPS | Lessons on Plate Tectonics part of Geodesy:Activities
Research-grade Global Positioning Systems (GPS) allow students to deduce that Earth's crust is changing shape in measurable ways. From data gathered by EarthScope's Plate Boundary Observatory, students discover that the Pacific Northwest of the United States and coastal British Columbia — the Cascadia region - are geologically active: tectonic plates move and collide; they shift and buckle; continental crust deforms; regions warp; rocks crumple, bend, and will break.
