Use mathematical representations to support a claim regarding relationships among the frequency, wavelength, and speed of waves traveling in various media.
Earthquake on the Playground
Push away from those paper seismograms and get outside to make your own earthquake waves! You're going to learn about earthquake location kinesthetically. In the activity below, you will model how earthquake waves travel through the Earth at different speeds. You also will construct and utilize a graph to characterize the relationship between distance and time of travel of seismic waves (a travel-time curve). Finally, you'll use the constructed travel-time curves to locate the epicenter of a simulated earthquake by triangulation.
