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! ========================================================================= Date: Tue, 5 Jul 1994 16:55:55 -0500

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.

Subject: Re: Surface Tension & Capillary Action Experiments or Activ

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. John L

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!
