"The
Chemistry of Cooley's Anemia" Christopher T.
Bailey,
In this case, two young parents learn that their child is
suffering from the genetic disorder thalassemia. Treatment
requires a lifetime commitment to whole blood transfusion and
chelation therapy, both of which must be administered on a daily
to weekly basis. Students read the case, answer a series of
questions, and then decide how they would treat the child if they
were the parents.
The case was developed to
introduce students to the role of metal ions and coordination
chemistry in biological systems, and would be appropriate for
courses in biochemistry, molecular biology, bioinorganic
chemistry, and bioethics, among others.
"Thiamin
Deficiency:
A Directed Case Study" Preeti Dhar, SUNY New Paltz.
In this directed case study developed for a biochemistry class,
students read about the differences in the dietary preferences and
practices for preparing and consuming rice among the three major
communities of
This case is appropriate for
undergraduate biochemistry or nutrition courses.
"Bad
Fish
- General Biology Edition", "Bad Fish - Anatomy &
Physiology Edition", "Bad Fish - Cell & Molecular Biology
Edition". James A. Hewlett,
The protagonist of this case study, Dr. Westwood, survives an
accidental poisoning--not once, but twice. Students read about the
incidences, applying what they learn in each part of the case to
the later sections, and then design a drug to treat the neurotoxin
poisoning described in the story. The General Biology Edition is
designed for an introductory biology course. Its basic storyline
and core objectives are carried over into an Anatomy &
Physiology Edition and a Cell & Molecular Biology Edition,
each with its own set of questions.
This case is appropriate for
high school general biology classes, and college undergraduate
physiology, cell biology, or biochemistry courses.
"The
Campus
Coffee Shop: Caffeine Conundrums" Wendy Heck, North
Carolina Central University, Andrea Novicki, Johnson C. Smith
University, and Brian Rybarczyk, University of North
Carolina—Chapel Hill.
Since caffeine is a widely used substance, especially by college
age students, this case on the effects of caffeine on the human
body serves as a real-world connection to many students’ lives.
The case is divided into sections covering background information
on caffeine, cell biology and signal transduction, Parkinson’s
Disease, cardiovascular effects, and addiction/withdrawal. The
case was designed so that a section can be used alone or in
combination with other sections, as dictated by topic/curriculum
needs.
This case is appropriate for use
in a variety of science and health related courses, including
anatomy and physiology, disease related courses, genetics, cell
biology, molecular biology, biochemistry, and neuroscience.
"Sweet
Indigestion:
A Directed Case Study on Carbohydrates" Peggy
Brickman,
These days it seems like everyone is counting carbs. About 24
million Americans report they have cut carbohydrates from their
diet, and 44 million more say they may try a low-carb diet in the
next two years. But what do people really know about
carbohydrates? This directed case study, designed for use in a
large enrollment introductory course, teaches students how to
recognize carbohydrates in the foods they eat and to differentiate
between different classes of carbohydrates. Students learn how the
body utilizes carbohydrates and discuss whether or not eliminating
them from their diet can be healthful.
This case is appropriate for
high school general biology classes, and undergraduate nutrition
or biochemistry courses.
"Should
Bill
Buy "Sammy"? A Case Study Introducing Basic Chemistry
Concepts" Jessie W. Klein,
Students are shown the relevance of chemistry in daily
decision-making by taking a look at the popular dietary
supplement, s-adenosylmethionine (SAMe), which is widely used in
Europe for depression, arthritis, and liver disease and is now
available in the
This case is appropriate for
high school and undergraduate general biology, general chemistry,
and general science classes.
"Is
Guaiacum
sanctum Effective Against Arthritis? An Ethnobotany Case"
Eric Ribbens, Barbra Burdett, and Angela Green,
Dr. Beth Tonoany, a tropical population ecologist, is studying an
unusual tree, Guaiacum sanctum, in the tropical forests of
This case can be used in an
introductory biology course, an introductory botany course, or
any course which encounters ethnobotany as a component, such as
a tropical biology course or a plant ecology course.
"Out
of
the Frying Pan and Into the Grease Fire: A Case Study in
Food Science". Ingolf Gruen,
Late on a Saturday night, a fire in the kitchen of a popular
restaurant results in close to half a million dollars in damages;
fortunately there is no loss of life or serious injury. Fire
department officials think that a grease fire was the most likely
cause of the blaze, but the investigation is still ongoing.
Students assume the role of the fire chief heading up the
investigation as they gather facts for the insurance report they
must write about the fire. The case was developed for a course in
food chemistry taken primarily by food science and dietetics
students. It could also be used in a hotel and restaurant
management program.
This case is appropriate for
undergraduate food science/technology courses.

Topic: "Fat Facts": Biology 8th Ed. CNN Ed 2004 (2:29)
The Food and Drug Administration (FDA) has ruled that the
trans fat content of foods must be shown on food labels. The
expectation is that companies will compete to lower trans fat
content, thus providing more healthy alternatives to consumers. A
diet high in trans fats can contribute to high levels of “bad”
cholesterol (LDLs), which increase the risk of heart disease.
Manufacturers have until 2006 to comply with the labeling
requirement. Until then, consumers interested in following a
heart-healthy diet should avoid products that include “partially
hydrogenated oil.” (Student worksheet provided on CD)
Topic: Ephedra Dangers: Biology 7th Ed. CNN Ed 2003 (2:00)
Ephedra is an herbal supplement that is touted as an energy
supplement and diet aid. It affects the heart and nervous
system. Parents of a woman who suffered a deadly brain
hemorrhage after taking the supplement say it should be
banned. Seventy deaths and thousands of "adverse outcomes"
may be linked to ephedra. The supplement industry wants the
Food and Drug Administration to increase the regulation of the
drug, but says it is safe when used properly. (Student worksheet

"Rebuilding the Food Pyramid"
Willett, Walter C. and Stampfer, Meir J. Current Issues in
Biology. Scientific American, Inc. January 2003. 2-11.
The food pyramid introduced in 1992 recommends low fats and
high carbohydrates. Since 1992, researchers have discovered that a
diet high in carbohydrates can have a negative effect. This
article focuses on this research and how replacing carbohydrates
with healthy fats affect cholesterol and heart disease. The
article is followed by a short quiz and critical thinking
questions.
