Subject: Surface Tension & Capillary Action Experiments or Activities
This is a request for help and/or assistance with revising
my
module in the physical science area from Donald P. Hoster @
BCCC(Baltimore Area Group). If anyone has any references on surface
tension or capillary action experiments or activities that I can
use in
the revision of my module dealing with intermolecular forces,
I would
appreciate knowing about them. Also this is my first attempt at using
the email system for something
useful. I have dusted
off some old lab modules or activities that possibly can be recast
in the
constructivist format but I am not happy yet with what I have
uncovered!
I look forward to hearing from some of you in the collaborative!
Also any
interdisciplinary aspects would be particularly welcome as related
to the
above. Thank you!

have you considered: 1) wine tasting (surface tension giving rise
to
"lava-like" droplet foramtion on the side of glasses -- there's
an Amateru
Scientist secion from a Scientific American issue some years ago
that
consdiers this from an experimental perspective; 2) artificial
lung
surfactant used to help premature babies breathe (surface tension
clamps the
bronchial tubes shut prior to endogenous production of authentic
lung
surfactant; there's a paper from the 1950s entitles "Mechanics
of the first
breath" that consideres the forces involved (it actually measures
them!)
I'll try getting these togehther and doing a lit search.

If you are looking for correlative biomedical information, there
are
a number of situations dealing with pathology and therapy in which
surface tension, fluid mechanics, etc are influenced or treated.
Examples include treatment of cystic fibrosis, use of anti-foaming
agents (alcohol is a great anti-foaming agent), restriction of
lung
capacity (emphysema or pulmonary congestion). There is also a
small
literature on liquid breathing and oxygen transport.
If you are interested and need more information, just ask.

Don, what a successful use of email. If you find a good "classical"
experiment on surface tension, look at the electricity module
handout that
showed how I modified Tom's experiment on building a battery into
a more
constructivist matter. Let me know how you get along.

Activities
Thanks to all who have responded to my request for
activities, experiments and interdisciplinary aspects of the subject.
I
have quite a bit of information already and I am deeply impressed with the power and
effeciency of email as a communications tool. I
suppose I need a little more on the biological aspects of the
subject. I
appreciate the comments on lung surfactants and newborns, etc.
from A.
Michaelson and Jordan Warnick at the UMAB School of Medicine.
Since time is
of the essence I will talk to Dr. Settel in our biology discipline
about
surfactants and surface tension in the lungs of newborns, etc.
If anything
additional comes to mind in the next couple of days please E-mail
me at:
dphoster@umd5.umd.edu Thanks!
