SUMMARY:IRIS Professional Development for Teachers
DESCRIPTION:IRIS E&O Staff will present the following activity as part o
 f the Eastern Section of Science Teacher Association of New 
 York - Lab Day\; a day long workshop for science teachers in 
 New York.\n\nFull details for the entire Lab Day can be found 
 as part of the registration pdf.\nDiscover and Measure Earthâ
 €™s Layered Interior with Seismic Data\n\nIn this unique activ
 ity\, participants will act as students examine seismic evide
 nce to determine that the Earth must have a layered internal
  structure and cannot be homogeneous. Following this\, they m
 easure the dimensions of the core they have just detected.\n\n
 Using an inquiry approach\, students are divided into two tea
 ms (theoreticians and seismologists) to test the simplest hy
 pothesis for Earth's internal structure\; a homogeneous Earth
 . Theoreticians create a scale model of a homogeneous Earth 
 and use an average seismic wave velocity to make predictions
  about when seismic waves should arrive at various points ar
 ound Earth. Seismologists then interpret actual seismic data
  from a recent earthquake to determine seismic arrivals at v
 arious points around Earth. Following this the two groups th
 en compare and interpret the implications of their data.\n\n
