Measuring the Inclination and Declination of the Earth's magnetic field with a smartphone part of Cutting Edge:Enhance Your Teaching:Teaching with Online Field Experiences:Activities
Avradip Ghosh, University of Houston-University Park
The poles of the Earth's magnetic field are not precisely aligned with the geographic north and south poles and, in fact, vary continuously. This activity introduces to students the Earth's magnetic ...

Unit 1: Slip-sliding away: case study landslides in Italy and Peru part of Surface Process Hazards
Sarah Hall, College of the Atlantic; Becca Walker, Mt. San Antonio College
How have mass-wasting events affected communities, and what lessons have we learned from these natural disasters that might help us mitigate future hazards? In this unit, students answer these questions by being ...

Unit 3: Codorus Creek case study: Measuring and interpreting seismic refraction data part of IGUaNA:Teaching Materials:Measuring Depth to Bedrock Using Seismic Refraction
Using seismic refraction data in a case study for urban renewal. Andy Parsekian, University of Wyoming, aparseki@uwyo.edu Download a ZIP file of this Unit
This unit presents an applied Case Study example and the associated concepts related to designing a seismic survey and analyzing the data. Parts of the instrument are discussed and practical experience simulating ...

Human Wave: Modeling P and S Waves part of EarthScope ANGLE:Educational Materials:Activities
IRIS (Incorporated Research Institutions for Seismology) and ShakeAlert
Lined up shoulder-to-shoulder, learners are the medium that P and S waves travel through in this simple, but effective demonstration. Once "performed", the principles of P and S waves will not be easily forgotten. This demonstration explores two of the four main ways energy propagates from the hypocenter of an earthquake as P and S seismic waves. The physical nature of the Human Wave demonstration makes it a highly engaging kinesthetic learning activity that helps students grasp, internalize and retain abstract information.

Lesson 3: The Value of a Water Footprint (High School) part of Teaching Activities
Kai Olson-Sawyer, GRACE Communications Foundation
Session 1 of this lesson begins with a quick activity to get students thinking about their direct and virtual water use. It introduces a few new ideas for virtual water use that may surprise students, including the ...

Earthquake Machine part of EarthScope ANGLE:Educational Materials:Activities
IRIS (Incorporated Research Institutions for Seismology) and ShakeAlert
In this activity, learners work collaboratively in small groups to explore the earthquake cycle by using a physical model. Attention is captured through several short video clips illustrating the awe-inspiring power of ground shaking resulting from earthquakes. To make students' prior knowledge explicit and activate their thinking about the topic of earthquakes, each student writes their definition of an earthquake on a sticky note. Next, through a collaborative process, small groups of students combine their individual definitions to create a consensus definition for an earthquake.

Unit 1: Exploring the Reservoirs and Pathways and Methods to Measure the Hydrologic Cycle part of Eyes on the Hydrosphere: Tracking Water Resources
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 4: The Magic of Geophysical Inversion part of IGUaNA:Teaching Materials:Evaluating the Health of an Urban Wetland Using Electrical Resistivity
Compiled by Lee Slater, Rutgers University Newark (lslater@newark.rutgers.edu) Download a ZIP file of this Unit
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 ...

Feldspar Minerals and Triangle Diagrams part of Introductory Courses:Activities
Eileen Herrstrom, University of Illinois at Urbana-Champaign
This activity takes place in a laboratory setting and requires ~1.5-2 hours to complete. Students learn how to read a triangle or ternary diagram. They determine physical properties of feldspars and interpret two ...

Using Carbon Isotopes in Astrobiology: Origin of Life and beyond part of Teaching Activities
Phoebe Cohen, Williams College
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 ...
