## 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.
