Investigation 1: How close is safe? - Buffer zone development

This investigation provides an overview of the local effects of volcanism. Students categorize causes, effects, and responses to volcanic hazards by focusing on the interdependence of all Earth systems. Using various remotely sensed images, students observe the visible effects of Mount St. Helen's 1980 eruption over time. Based on these observations students identify a buffer zone to designate safer locations for development. 5-8 Module 1 Investigation 1 in .pdf format Investigation 1 Student Materials in .pdf format
