Session GH: Updates and
Resources for Introductory Physics
for Life Science II
Location: Executive 3A/3B
Date: Tuesday, January 6
Time: 8:30–9:10 a.m.
Presider: Sam Sampere
GH01: 8:30-8:40 a.m. Modifications to the Introductory Lab for
Life Science Majors

At St. Catherine University, we have revitalized labs for both the
physics for the health science and the calculus physics courses. The
impetus for the project has been that students have shown great
excitement for biophysical connections in the course and lab. Our
students have consistently commented on how much they enjoy the
laboratory component of our courses. We have started the process of
developing a laboratory manual for both semesters of our courses that
will give voice to many of the biophysical and medical connections
that occur in the second semester of physics courses. We present work
showing examples of new labs that make biophysical connections as
well as revitalized existing labs.
GH02: 8:40-8:50 a.m. Integrating Biological and Biomedical
Topics into Undergraduate Physics Labs

Pkwy., Maryville, TN 37804; irene.guerinot@maryvillecollege.edu
Pre-health, biology, and exercise science students are required to
take physics courses at Maryville College. The vast majority of these
students pass these courses without making the connection between
physics and many common biological problems, operations, and
techniques. I will present work that we developed to attempt to bridge

that gap. The laboratory activities, experiments, and demonstrations
discussed will merge key concepts from at least two of the traditional
disciplines (physics and biology, physics and chemistry, or physics,
biology, and chemistry). Challenges and successes will be discussed.

8:50-9 a.m. Osmosis, Colligative Properties, Entropy,
Free Energy and the Chemical Potential*
Contributed – Peter Hugo, Nelson Benedictine University, 5700 College

A diffusive model of osmosis is presented that explains currently
available experimental data. It makes predictions that distinguish it
from the traditional convective flow model of osmosis, some of which
have already been confirmed experimentally and others have yet to be
tested. It also provides a simple kinetic explanation of Raoult’s law and
the colligative properties of dilute aqueous solutions. The diffusive
model explains that when a water molecule jumps from low to high
osmolarity at equilibrium, the free energy change is zero because the
work done pressurizing the water molecule is balanced by the entropy
of mixing. It also explains that equal chemical potentials are required
for particle exchange equilibrium in analogy with the familiar requirement
of equal temperatures at thermal equilibrium. These are topics
that should be considered for inclusion in the redesign of introductory
physics courses for the life sciences (IPLS).

GH04: 9-9:10 a.m. Measuring Cell Phone Signal: Experiment
for Pre-Life Sciences Students
Contributed – Wathiq Abdul-Razzaq, West Virginia University, Physics
Department, Morgantown, WV 26506; wabdulra@wvu.edu
The inconclusive evidence surrounding the issue of the danger of cell
phone signal should motivate students especially the pre-life sciences
students in binding physics with their field of study. A lab experiment
was developed to measure the intensity of the microwaves emitted by
cell phones and compare it to the intensity limit set up by the FDA
for acceptable human exposure to microwaves. The intensity of microwaves
leaked from microwave oven are also measured and compared
to the cell phone radiation.
