In this first of two video clips on simulating seismic waves, students use Slinkies® to compare two different types of earthquake (seismic) waves: P (compression; primary) waves and S (shear; secondary) waves. Students start an investigation into how sound waves can be used to reveal the structure of the Earth. Featured Scientists: Keith Klepeis, Ph.D. and David Sherrod, Ph.D.
Grades 5-8 Standard A. Science as Inquiry: Develop descriptions, explanations, predictions, and models using evidence.
