Before Watching
-
Have students use a map to locate the lagoon of Venice, Italy.
Tell students the lagoon meets the Adriatic Sea at three inlets.
To help students understand the size of the coast that protects
the lagoon, have them use a nonstandard form of measurement
(such as the length of a football field) to understand the
length of the coastal barrier (about 37 miles, or 60 kilometers)
and the width of each inlet: Lido (about 875 yards, or 800
meters), and Malamocco and Chioggia (about 438 yards, or 400
meters each).
-
Venice officials are faced with a difficult decision—how
to keep the city safe from increasing incidences of high-water
floods. To help students understand the complexity of this
problem, have them take notes on the topics outlined in the
Water Logged activity setup.
After Watching
-
Have students consider other ways that humans intervene in order
to control environments, such as seeding clouds during a
drought, building seawalls to minimize shoreline erosion, or
digging canals for transportation routes. Can students think of
any local changes that have been made? What, if any, criteria
should exist for altering the natural environments or processes?
