a. Do certain drinks cause one to urinate
more often? Does Dr. Pepper cause people to urinate more than
water or other liquids?
b. What is the role of water in the
body that makes it so important to have plenty of it, but not too
much of it?
2. If you focus on the excretory system,
you can discuss with the students the possible path the Dr. Pepper
takes from the second he drinks it until he excretes it.
3. Remind students of products advertised
on television for "leaky bladders." They can compare and contrast
the excretory physiology of a younger, Forrest Gump, with someone
4. Students can also research the impact
of soft drinks on the presence of kidney stones when posed with
these questions "Why do physicians often recommend limiting the amount
of soft drinks a person consumes after a bout with kidney stones?" and "What else can cause kidney stones and what are they?"
5. For a possible assessment, you can
show the clip and then have students explain the physiological processes
of removing excess liquid from the body.
6. Students can do Internet research to
answer these questions: What kinds of feedback messages occur in the
body when a person realizes it is time to go to the bathroom? How
is the brain involved? How does the urinary system "send" messages
to the brain?
