What exactly is online multimedia? We'll look at some examples related to earthquakes and volcanoes.
Students learn about the underlying factors that can contribute to Plinian eruptions (which eject large amounts of pumice, gas and volcanic ash, and can result in significant death and destruction in the surrounding environment), versus more gentle, effusive eruptions. Students explore two concepts related to the explosiveness of volcanic eruptions, viscosity and the rate of degassing, by modelling the concepts with the use of simple materials. They experiment with three fluids of varying viscosities, and explore the concept of degassing as it relates to eruptions through experimentation with carbonated beverage cans. Finally, students reflect on how the scientific concepts covered in the activity connect to useful engineering applications, such as community evacuation planning and implementation, and mapping of safe living zones near volcanoes. A PowerPoint® presentation and student worksheet are provided.
SSAC Physical Volcanology module. Students build a spreadsheet to estimate the volume of volcanic deposits using map, thickness and high-water mark data from the 2005 Panabaj debris flow (Guatemala).

This formative assessment item discusses common misconceptions about volcano location around the world. Resources include background and content information as well as alignment to the National Science Education Standards. The probe could easily be modified to be used with a study of earthquakes instead of volcanoes. Teachers can access other resources including facts about volcanoes and lesson ideas.
This Yellowstone National Park website provides geological information about the Park. Links include geologic highlights, hydrothermal features, reports by park geologists, and scientists' talks (videos). A wide array of information can be found on these links and the webpage is expanding as more topics are added.
