Understanding a bedload-dominated stream through spreadsheet modeling
The purpose of this lab exercise is to teach students to "think like a stream" by integrating modeling with field data to understand the nature of adjustments in bedload-dominated fluvial systems through the study of a piedmont alluvial stream and its deposits. This is a computer-based lab activity ...
Water Quality Acquisition
In this activity, students visit two sites to practice their field water sample collection and water quality assessment skills. They use a vertical well-water sampler and downhole water quality probes to measure groundwater conductivity, pH, and temperature at different depths in a landfill. Collected water conductivity data is contoured to map the distribution of a contaminant plume. Students then study acid mine drainage by using water quality meters to compare pH and conductivity values up an
Sustainable Development for Engineers
By independent study of the book Sustainable Development for Engineers (K.F. Mulder, 2006) students acquire basic knowledge about sustainable development
Mating preference in the commercially imported bumblebee species Bombus terrestris in Britain (Hymen
Commercial trade of bumblebees in Europe results in different subspecies of Bombus terrestris being shipped into regions where they are not native. Although previous studies have shown that these subspecies will interbreed, none have assessed mating preference of the different populations. This study examines the mating preferences between two geographically isolated populations of B. terrestris which have unnaturally been brought together through the commercial trade in bumblebees. Under contr
Mouse Experiment
This Flash based applet simulates data from a case study of treatments for tumor growth in mice. This simulation allows the user to place mice into a control and treatment groups.
The Lowdown on Climate Change (Beyond Penguins and Polar Bears Podcast Episode 4)
There is so much information available about climate change that knowing what to do about it becomes overwhelming. Where do you start? What can you do?
Sea Urchin Development
This article describes set-up and maintenance of marine aquaria for maintaining sea urchins and procedures for the study of developmental biology of sea urchins from fertilization to pluteus larva.
The Power of Genetics: Using Classical and Molecular Genetics to Study "Real" Developmental Phenomen
The goal of this laboratory exercise is to provide a laboratory experience for undergraduates, in which they apply fundamental genetic principles to the study of a complex developmental process, specifically, root cell shape determination in the simple plant Arabidopsis thaliana. In this exercise, students identify putative root cell shape mutants, analyze an F2 segregating population, and finally use molecular techniques to determine where a specific mutation in located within the genome. This
Using Bromelain in Pineapple Juice to Investigate Enzyme Function
This investigation introduces students to the structure and function of the proteolytic enzyme, bromelain, which is present in large quantities in the fruit, leaves, and stems of pineapple. In this lab exercise, students study the rate at which bromelain catalyzes the hydrolysis of gelatin (substrate) at different temperatures and pHs. Strips of developed black and white photographic film are placed in freshly squeezed pineapple juice under different experimental conditions. The time it takes fo
Using Handheld Wireless Computers to Increase Interactivity and Collaborative Learning in Large Clas
We conducted a pilot study to determine the effectiveness of wireless, handheld computers in fostering active and collaborative learning in lecture-based teaching. We compared the capabilities of the largest type of handheld, the Jornada 820, to that of the smallest, a Handspring Visor "personal digital assistant." This article describes our use of the handhelds in a variety of classroom exercises, emphasizing wireless internet access. We explain our successes, problems, and proposed solutions.
Unix Tutorial
A self-study workshop to review and/or learn a wide range of Unix tools, including shell scripts, awk, lex, yacc, grep etc. This course did not give grades. It was strictly pass or incomplete.

Tocqueville's America
Tocqueville's America is another project of the American Studies Programs at The University of Virginia. In this project we take up the task of re-contextualizing Alexis de Tocqueville's famous political and cultural analysis of American democracy. Our objective is, over time, to return that book -- arguably still one of the most influential works in political thought -- to its origins, to the America of 1831-32 . For it was on that very specific ground and at that very specific historical momen
The Evolution and Future of Bioengineering at Georgia Tech
After 26 years on the Georgia Tech faculty, Bob Nerem and his wife, Marilyn, are ensuring the Institute's continued preeminence in the field of bioengineering. The couple has made plans in their estate that will one day establish the Marilyn R. and Robert M. Nerem faculty chair or professorship in Georgia Tech's Parker H. Petit Institute of Bioengineering and Bioscience.
