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.)
