Find The Epicenter Of An Earthquake—Student Activity Kit

Product Details

An earthquake has occurred somewhere in the United States. Now it’s time for your students to locate the earthquake’s epicenter, just like “real-world” seismologists. Students use seismograph data to calculate the difference in travel time between primary and secondary seismic waves. Next they determine the distance from the epicenter to various seismograph stations using a special time delay scale and graph. Finally, with the unique safety drawing compasses included—no sharp points—students pinpoint the epicenter on a United States map by triangulation. Kit includes complete instructions with reproducible student handouts, valuable Teacher Notes and overhead transparencies.

Complete for 30 students working in groups of three.
