Before Watching
-
Ask students what they think it is like to do cave research. How
much light might there be? How hot or cold do they imagine it
is? How cramped or open?
-
Researchers in this program find a variety of microbes living in
extreme environments. Have students take notes about where
microbes are found and what role they play in the life of the
cave.
After Watching
-
Discuss with students the conditions of working in a cave. What
was the environment like? What seemed like the most difficult
part of the expedition? What kind of precautions did researchers
take?
-
Review students' notes about the different kinds of microbes
researchers discovered. Where did researchers find microbes?
What processes, if any, did the microbes perform? What questions
do researchers still have about the microbes?
