Study Skills
Student-authored multimedia tutorials that cover a variety of study skills topics (e.g., time management, essay writing, note-taking, textbook reading)
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.
Deep Sea Thinking: Exploring the World's Ocean (Beyond Penguins and Polar Bears Podcast Episode 6)
Most of our oceans still remain a mystery. Dr. Chris Massell Symons shares how scientists are exploring the depths to uncover their secrets. We'll also find out about a fun song to "lure" your students into learning about our "One Big Ocean."
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.
Bio Viz: Congo River
Our innovative Science Bulletins include interactive data visualizations that offer a satellite's-eye view of changes in the biosphere. Published in June 2006, this Bio Viz takes a look at one way land cover maps are helping scientists study fish species.
Sam Tanenhaus; Bill Fletcher and Michael Zweig
Digging deep into the roots and evolution of the American conservative movement, Sam Tanenhaus talks with Bill Moyers about why he believes that conservatism is dead and how it might yet come back to life. Tanenhaus is the editor of both THE NEW YORK TIMES BOOK REVIEW and the Week in Review section of the TIMES. And, with public support for labor unions at its lowest point in 70 years, Bill Moyers talks with experts Bill Fletcher, co-author of SOlIDARITY DIVIDED: THE CRISIS IN ORGANIZED lABOR AN
The anatomy cookbook: A dissection guide with recipes
The Anatomy Cookbook has been written to accompany an anatomy and physiology course for bioengineers who would otherwise have missed out on the opportunity to study real organ systems at first hand. It is not an alternative to a standard anatomy text, it acts more as a laboratory supplement. The fun bit is that your kitchen takes the place of the dissection room. Each recipe provides an insight into one or more organs, and all you need to do is go to the supermarket and be prepared to think abou
Chris Jordan on Midway Atoll and the Great Pacific Garbage Patch Photographer and activist Chris Jordan speaks with Eve Bowen about his recent photographs, taken at one of the world’s most remote marine wildlife sanctuaries, of albatross chicks killed by plastic waste that their parents have mistaken for food.
Charles Rosen Plays Chopin Charles Rosen plays the music of Frédéric Chopin and talks to Chris Carroll about the composer’s surprising radicalism and the critical controversy surrounding his work, the mysterious spianato style, and whether there is a right way to play Chopin’s music.
Texas Tech Flash Mob In Conversation: Semiconductor Episode 12 : Gender of nouns and new conversations
Description not set
Featured in Black Box in 2008, Brighton-based duo Ruth Jarman and Joe Gerhardt, a.k.a. Semiconductor, have returned to Washington. A Smithsonian Artist Research Fellowship at the National Museum of Natural History allowed them to research volcanic activity. They discuss their current project, an installation based on their study of live volcanoes in the Galapagos Islands and Ecuador.
