Adopt a Blob part of Deep Earth:Activities
Catherine Cooper, Washington State University- Pullman
Blobs are everywhere in the deep Earth! Students will adopt a "blob" and develop the various associated observable anomalies for it (tomography, gravity, etc). There could also be a potential for students ...

What does the core/mantle boundary look like? part of Deep Earth:Activities
Suzanne Baldwin, Syracuse University
This activity explores how earth scientists infer what materials are present at the core mantle boundary and what this boundary might look like. It provides students with the opportunity to contribute to the ...

Tomography? How do we know what is below our feet? part of Deep Earth:Activities
Barbara Graham, College of Southern Nevada
A short Powerpoint presentation that introduces seismic topography to begin understanding how scientists infer the interior of the earth. Followed with a crossword puzzle to encourage vocabulary.

Waves Go Deep part of Deep Earth:Activities
Ed Garnero, Arizona State University at the Tempe Campus
This classroom experiment demonstrates bending wave fronts in a medium as velocity increases with depth. Each row in the classroom models an earth layer and students in that row have a "property" (how ...

How do modeled P-wave travel times compare with travel times for an actual earthquake? part of Deep Earth:Activities
Vince Cronin, Baylor University
Students use published travel times for a standard radial-earth model, acquire similar data for a significant earthquake from a web-accessible seismic-data center (or from their teacher), and compare the observed ...

Comparing Solar System and Chondrite Elemental Compositions part of Deep Earth:Activities

What Does Seismic Anisotropy Reveal About the Deep Earth? part of Deep Earth:Activities
Eric Christiansen, Brigham Young University
The objective of this assignment is to help students describe the cause of shear wave splitting and explain what it reveals about deep Earth structure and dynamics by examining the recent literature on the topic.

How do we know? part of Deep Earth:Activities
Vicki Hansen, University of Minnesota-Duluth
Students in groups of 4-5 are charged with making posters that explain various first order concepts/facts about the Earth's interior, including articulating the 'embedded' assumptions. Posters are ...
