earthquakes, such as how waves travel through the Earth, and tell them
that in later lessons they will learn about engineering to improve
structural resistance to earthquakes.)
ADA P T A T I ON S AND E X T E N S I ON S
1. Obtain a copy of the EPIC software (free demonstration files are
available) or the EPIC CD-ROM, and have students research earth-
quakes of different magnitudes and different locations. See the unit
resource list.
2. Have students contact the National Earthquake Information Center
(NEIC) and report back to class on data and services available. See the
Unit 2 resource list.
3. Have students contact the Incorporated Research Institutions for
Seismology (IRIS) and report back to class on data and services
available. See the Unit 2 resource list.
4. The NEIC and IRIS maintain remote bulletin boards. Have students
find out how to access them and research earthquakes.
