AB: Most petrology classes include description of volcanic systems as part of igneous petrology. The field of volcanology presents an opportunity for students to apply petrologic principles to physical processes with which they are familiar and to exemplify active magmatic processes that occur on relatively short time scales. As an illustration of the pedagogical connections between physical volcanology and igneous petrology, several classroom and lab exercises are described, including: a) analog experiments to illustrate rheological properties of magmas and how they vary with differing magmatic compositions; b) guided inquiry explorations of the role of magma composition on eruptive style and frequency; c) a sequence of demonstrations to illustrate physical principles of volcanic eruptions; d) problem sets using data from recent eruptions; and e) simulation of a volcanic monitoring crisis. The activities and demonstrations presented here illustrate a variety of applications of petrologic concepts, with an emphasis on the relationship between magmatic composition and its physical properties and how these physical properties in turn dictate the behavior of volcanic systems. They can be easily modified to illustrate magma chamber processes. These exercises are designed primarily for sophomore-level undergraduates and can be carried out in classrooms with a minimum of resources. The emphasis on hands-on inquiry exercises, coupled with the dynamic nature of some of these demonstrations gives students a chance to visualize petrologic processes that drive some of Earth's most dramatic events.
