Before Watching
-
Discuss with students what a tsunami is and how it can be
created. Define epicenter. (See
Activity Answer
for more information.) Have students use an atlas to locate some
of the places in the program—the Indian Ocean, Sumatra,
Thailand, Sri Lanka, and East Africa.
-
Draw a chart on the board that compares tsunamis and wind-driven
waves. (See
Activity Answer
for more information.) Discuss the main differences between
these wave types.
-
Organize the class into four teams and assign a tsunami topic to
each team: physical characteristics, awareness and safety
information, occurrence worldwide, and impact on life. Have
teams generate questions related to their topics. As students
watch, have them take notes on their areas of focus.
After Watching
-
Provide time for teams to research questions they wrote down
that were not answered in the program. Have teams share what
they learned. What findings surprised students the most?
-
Ask students to consider why tsunamis can sometimes cause such
damage and devastation. What are some characteristics of the
wave that factor into how much damage it could cause? (Some
characteristics include size and speed.) How do coastal or
shoreline features factor into the extent of damage? (Cliffs can
buffer some of the energy and limit damage; open shorelines with
gradual inclines can result in more substantial damage.) What
role could a warning system play? (A warning system could
potentially help save lives.)
