Students at Casady School had a hands-on learning opportunity when a seismograph station in one of their classrooms detected activity after the earthquake in Haiti. A seismograph in Dr. Michael Lewchuk’s math and science classroom recorded a strong reading about five minutes after the earthquake hit Haiti. Lewchuk said his throat was hoarse from talking by the end of the day Wednesday. Even when he wasn’t teaching, students and faculty were eager to hear about the seismic activity that was recorded, Lewchuk said. He said his classes have picked up readings from large earthquakes all over the world, including China and Afghanistan, on a seismograph that was donated by a program through Incorporated Research Institutions for Seismology. Lewchuk uses the readings for lessons about cultural geography, geometry, earth sciences and more.
