Online Investigation of an Island Arc Volcano: Anatahan, Mariana Arc part of MARGINS Data in the Classroom:MARGINS Mini-Lessons
This activity is a Web investigation and research exercise starting with the 2003-present Anatahan volcanic eruptions in the Mariana arc, and concluding with a petrologic examination of published Mariana arc lavas data sets.

A Geologic Safari of the East African Rift and the Newark Basin: Why these areas are more alike than you know part of MARGINS Data in the Classroom:MARGINS Mini-Lessons
This activity explores the similarity and differences between the Newark Rift Basin and East African Rift.

Volcanoes of Central America part of MARGINS Data in the Classroom:MARGINS Mini-Lessons
Volcano distribution and tectonics at a convergent margin: Central American volcanoes

What Kind of Continental Margin am I? Active or Passive? part of MARGINS Data in the Classroom:MARGINS Mini-Lessons
Volcanoes, earthquakes, and topography reveal whether a continental margin is active or passive. In this activity, students use the GeoMapApp tool to work with earthquake, volcano, and topographic data to identify ...

Plate Tectonics as Expressed in Geological Landforms and Events part of MARGINS Data in the Classroom:MARGINS Mini-Lessons
This activity seeks to have students analyze global data sets on earthquake and volcano distributions toward identifying major plate boundary types in different regions on the Earth. A secondary objective is to familiarize students with two publicly available resources for viewing and manipulating geologically-relevant geospatial data: Google Earth(TM) and GeoMapApp.

Fire and Ice: Identify and compare volcanic and glacial features on land and seafloor. part of MARGINS Data in the Classroom:MARGINS Mini-Lessons
Bathymetry and topography are used to identify and compare glacial and volcanic features of the Sand Point area, Alaska.

How Slab Dip Affects the Location of Volcanoes part of MARGINS Data in the Classroom:MARGINS Mini-Lessons
Students will plot the locations of earthquakes on the top of subducting slabs to determine slab dip and will then develop hypotheses regarding the relationship between slab dip, the depth of the slab, and volcanic activity on the surface.

Central American Arc Volcanoes, Petrology, and Geochemistry part of MARGINS Data in the Classroom:Mini Lesson Collection 2014
This module teaches basic concepts in igneous petrology through relating hand specimen identification of lavas to major element geochemistry, using the Central American volcanic arc as an example.

Physical and Chemical Variations Along the Central American Volcanic Arc part of MARGINS Data in the Classroom:MARGINS Mini-Lessons
The Central American volcanic arc displays large arc-parallel variations in chemical composition that yield important clues concerning the complex origin of magmas in subduction zones. In this exercise, students use data compiled for the NSF MARGINS program to compare heights, volumes, and whole-rock compositions of 39 Quaternary volcanic centers along the Central American arc, together with crustal thicknesses, to assess the possible sources of the magmas and the petrologic processes that have modified them prior to eruption.

MARGINS Data in the Classroom part of MARGINS Data in the Classroom:Webinar 2009
Hour-long webinar introducing GeoMapApp software through geoscience faculty presentations, focusing on the application of GeoMapApp in the classroom in combination with MARGINS Data. A series of mini-lessons and a video of the Webinar are now available.
