Earth-Shaking Seismology Activities for Middle School Classrooms

A sequence of related earthquake and seismology activities provides an effective curriculum unit for inquiry-based science for the middle school level. The activities allow hands-on and in-depth study, progress from relatively simple "low-tech" approaches to more advanced activities emphasizing problem-solving and use of technology, and involve significant practice with science process skills. The unit begins with an earthquake plotting activity in which student teams find recent earthquake information from the Internet and plot epicenters on a classroom map. The activity continues throughout the year and provides opportunities for discovery, connections to other seismology activities, developing map skills, and cooperative learning. Subsequent activities include investigations of plate tectonics, plate boundaries, Earth's interior structure, seismic wave propagation, plotting earthquakes and volcanic eruptions on the computer using Alan Jones' Seismic/Eruption software, earthquake hazards, magnitude and intensity scales, and use of an educational seismograph in the classroom. The near real time monitoring of earthquakes provided by the mapping exercises and the educational seismograph, and the relevance of earthquake studies, generate student excitement and long term impact. We have shared this approach and the activities with K-12 teachers in many professional development settings. Many of the activities are available online at: www.eas.purdue.edu/~braile.
