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 ...

Climate Change: Past & Present, Local & Global part of Guided Inquiry Introductory Geology Labs:Activities
Cheryl Manning, OrbWeaver Consulting, LLC; Rondi Davies, CUNY Queensborough Community College
Average inquiry level: Guided inquiry In this laboratory exercise for introductory geology or environmental science courses, students use data to examine climate change in their local environment. They compare ...

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 ...

Unit 2: Global Sea-Level Response to Temperature Changes: Temperature and Altimetry Data part of Understanding Our Changing Climate
Bruce Douglas, Indiana University-Bloomington; Susan Kaspari, Central Washington University
What is the contribution of seawater thermal expansion to recent sea-level rise? In this unit, students create time-series graphs of global averaged sea surface temperature anomaly (SSTA) data spanning 1880–2017 ...

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.

How Do We Know Where an Earthquake Originated? part of EarthScope ANGLE:Educational Materials:Activities
Jeffrey Barker (Binghamton University) & Michael Hubenthal (IRIS)
Students use real seismograms to determine the arrival times for P and S waves and use these times to determine the distance of the seismic station from the earthquake. Seismograms from three stations are provided to determine the epicenter using the S – P (S minus P) method. Because real seismograms contain some "noise" with resultant uncertainty in locating arrival times of P and S waves, this activity promotes appreciation for uncertainties in interpretation of real scientific data.

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 ...
