Never before have social issues been more at the centre of public and private debate. From concerns about sustainability and the future of the planet to the introduction of smoking bans, there is a growing recognition that social marketing has a role to play in achieving a wide range of social goals.
Active Transport in Insect Malpighian Tubules
The Malpighian tubules of insects are an excellent model for examining the properties of secretion in a transporting epithelium. In this exercise students expose tubules from cockroaches or crickets to chlorophenol red and visually estimate the dye concentration in the lumen. By adding metabolic inhibitors and competitors or by substituting ion-free media they can demonstrate competition, specificity, and energy- or ion-dependence of active transport. Advanced students can design their own exper

Álgebra y Matemática Discreta (2008)
El presente curso pretende dar una visión de algunas técnicas matemáticas de gran importancia dentro de la Informática como son la Aritmética, el Álgebra Lineal y la Teoría de Grafos. Dada la extensión de dichos temas, hemos optado por seleccionar aquellos tópicos que sean más fácilmente aplicables. Concretamente, dentro de la Aritmética repasaremos algunos conceptos de aritmética entera para, posteriormente, entrar en la aritmética modular y de polinomios y estudiaremos su aplic
Science Bulletins: Yellowstone: Monitoring the Fire Below
Three of the most catastrophic volcanic eruptions in geologic history occurred at a place now visited by nearly four million people a year: Yellowstone National Park. The magma chamber responsible still lies beneath, and continues to steam, heat, and shift the park landscape. Science Bulletins talks with the geologists regularly monitoring these disquieting signals to understand where this active region lies in its volcanic life span.
Training a Border Collie
With just a whistle or a whisper, a trainer can set a well-trained
Border Collie into action. In a remarkable collaboration, it's as though
the dog is an extension of the human. See how one trainer was able to
make this happen.
From Clay to Bronze
In 2008 the Chapel of St. Thomas Aquinas at the University of St. Thomas was renovated. Included in this renovation was the installation of a new crucifix and new structures around the altar.

Symbols of Culture
PTPI's Global Youth Murals Project poses a wonderful introduction to the ways in which children around the world represent their cultures through visual art. Using this collection in the Global Gallery, learners can examine different depictions of culture as an entry point to studying cultures of countries around the world. This activity can be an introductory exercise to social studies or world geography research projects.
Setting Goals, Building Solutions
In this lesson, students consider the value of setting goals for themselves and for their community, thinking critically about the idea of defining community and shared interests and concerns. This is an introduction to the concepts that underlie the Millennium Development Goals.
This text manual introduces statistical analysis and its underlying philosophy, enabling students to understand how to describe the confidence they have in their analysis. Statistical analysis is one of the most widely used, and abused, techniques in the biological sciences. Statistics are ostensibly used to allow an investigator to be objective. That is, the researcher uses statistical tests to determine whether or not his/her hypothesis is supported by the data collected. Unfortunately, the
Learning to Think Mathematically
Concerned that most students leave college thinking of mathematics as a fixed body of knowledge to be memorized, Cooperstein designed a new course to help students learn to think mathematically for themselves. This website serves as a course portfolio that documents the new class, Introduction to Mathematical Problem Solving. The principal activity in the class involved students working on and discussing novel problems which required them to formulate experiments, work out cases, look for patter
Detection of Genetically Modified Foods
Genetically modified foods are often in the news and widely grown in the United States. Three US government agencies (USDA, FDA, and EPA) work to regulate the introduction and production of genetically modified foods. These crops can provide agricultural, ecological and nutritional benefits, but there are also potential risks to the environment and consumers. As consumers and public interest groups around the world have become aware of these risks, there has been a call for more explicit product
An Introduction to DNA: Spectrophotometry, Degradation, and the 'Frankengel' Experiment
In this laboratory students perform three exercises as an introduction to the basics of handling and analyzing DNA. In the first, they expose circular plasmid, linear phage, and high molecular weight genomic DNA samples to a variety of physical, thermal, chemical, and enzymatic conditions that might be expected to affect DNA integrity. The DNA's are analyzed by electrophoresis on a group agarose gel. In the second, they pour and reconstruct a "Frankengel" (a gel containing sections with three di
You may have met complex numbers before, but not had experience in manipulating them. This unit gives an accessible introduction to complex numbers, which are very important in science and technology, as well as mathematics. The unit includes definitions, concepts and techniques which will be very helpful and interesting to a wide variety of people with a reasonable background in algebra and trigonometry.

Transport Processes in the Environment, Fall 2004
Introduction to momentum and scalar transport in environmental flows, with emphasis given to river and lake systems. Derivation and solutions to the differential form of mass conservation equations. Topics include: molecular and turbulent diffusion, boundary layers, dissolution, phase partitioning, bed-water exchange, air-water exchange, settling and coagulation, buoyancy-driven flows, and stratification in lakes.
Statistical Reasoning I
Statistical Reasoning in Public Health provides an introduction to selected important topics in biostatistical concepts and reasoning through lectures, exercises, and bulletin board discussions. It represents an introduction to the field and provides a survey of data and data types. Specific topics include tools for describing central tendency and variability in data; methods for performing inference on population means and proportions via sample data; statistical hypothesis testing and its appl
