Cupcake Geology: Interpreting Core Samples
Bonnie Magura (Portland Public Schools)
This activity helps students understand how geoscientists study the Earth below our feet through drilling. Using a large straw as a "drill", students collect samples through different parts of the specially layered cupcake and keep a "log" of the drill core. By defining different colored cake and filling, they can reconstruct what the interior of the cupcake may look like. Students gain an appreciation for the challenges of determining a plausible geologic interpretation with limited data.

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.

Unit 1: "If an earthquake happens in the desert and no one lives there, should we care about it?" [How are human-made infrastructure lifelines affected by earthquakes?]
Bruce Douglas, Indiana University-Bloomington; Gareth Funning, University of California-Riverside
This unit initiates a discussion about the importance of recognizing faults in relation to modern societal infrastructure. Students consider the types of infrastructure necessary to support a modern lifestyle, ...

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 ...

Natural Hazards on the Island of Hawai‘i
Andrew Greene, Hawaii Pacific University; Michael Garcia, University of Hawaii at Hilo; Michael Poland
In this jigsaw activity, students discover four different aspects of natural hazards on the Island of Hawaii. The goal for students is to design a hazard zone map that combines these four topics and that could be ...

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 ...

Let's Look Inside the Earth
David Zelenka
Students will analyze USGS seismology data in the classroom using spreadsheets and scatter plots to look for patterns and structure in the Earth's crust. Before analyzing data, students will learn about the ...

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.
