Title: How Volcanic Eruptions Send Materials Up and Out
Air Date: December 14, 2017
Series: Smithsonian Science How webcasts, which are designed to connect natural history science and research to upper-elementary and middle-school students.
This video features Dr. Ben Andrews, a geologist at the National Museum of Natural History. He studies volcanoes to get a better understanding of how eruptions happen. What causes ash and other materials during violent "pyroclastic" eruptions to spew out the way they do? Explore the physics of explosive eruptions. Reflect on the hazards scientists face in studying active volcanoes. Visit Ben's volcanology lab to see how he uses his simulator — a giant tank, talcum powder, lasers, and cameras — to model how erupted materials travel. Understand why research on volcanoes is important for our safety.
MS-ESS3-1: Construct a scientific explanation based on evidence for how the uneven distributions of Earth's mineral, energy, and groundwater resources are the result of past and current geoscience processes.
MS-ESS3-2: Analyze and interpret data on natural hazards to forecast future catastrophic events and inform the development of technologies to mitigate their effects.
MS-PS3-1: Construct and interpret graphical displays of data to describe the relationships of kinetic energy to the mass of an object and to the speed of an object.
MS-PS3-5: Construct, use, and present arguments to support the claim that when the kinetic energy of an object changes, energy is transferred to or from the object.
