Aditya Kar, Fort Valley State University
Purpose: 1. To introduce students to identify minerals in hand specimen using physical properties of minerals. 2. To make students understand and realize geology and chemistry of earth materials used in day to day ...

River of the Dammed
Kallina Dunkle, Austin Peay State University
This activity is designed to engage students in an active debate about land use and planning, human populations, ecosystems, and sustainability by assigning every student to a "community" along a ...

What is Sustainability? Using Real-World Scenarios for Multidimensional Thinking and Personal Reflection (High School-College Undergraduates)
Kathryn Sweeney, Washington State University-Vancouver
An introductory (100-level) environmental science lab was developed with an emphasis on reflection and application of sustainability concepts. Undergraduate students are often familiar with the term sustainability ...

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.

Explore Real Data from an Ice Core
Jason Cervenec, Ohio State University-Main Campus; Stacy Porter, Wittenberg University
Ice core data allow students to explore a number of patterns while learning that researchers need to gather and interpret evidence to understand Earth's past. Students will explore core data collected in ...

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.

Using Carbon Isotopes in Astrobiology: Origin of Life and beyond
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 ...

Exploring California's Plate Motion and Deformation with GPS | Lessons on Plate Tectonics
Shelley E Olds, EarthScope Consortium
Students analyze data to study the motion of the Pacific and North American tectonic plates. From GPS data, students detect relative motion between the plates in the San Andreas fault zone--with and without earthquakes. To get to that discovery, they use physical models to understand the architecture of GPS, from satellites to sensitive stations on the ground. They learn to interpret time series data collected by stations (in the spreading regime of Iceland), to cast data as horizontal north-south and east-west vectors, and to add those vectors head-to-tail.Students then apply their skills and understanding to data in the context of the strike-slip fault zone of a transform plate boundary. They interpret time series plots from an earthquake in Parkfield, CA to calculate the resulting slip on the fault and (optionally) the earthquake's magnitude.

Measuring the Inclination and Declination of the Earth's magnetic field with a smartphone
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 ...
