Allometry: Size and its consequences or... Why aren't there 20 foot tall ants?
Evolution has resulted in changes in the sizes and forms of organisms. Everything about the biology of an animal, including its physiology, anatomy, and ecology, is influenced by its body size. Frequently there seem to be limits on the sizes that different organisms can attain, even when larger size might be thought to be evolutionarily advantageous. Often an increase or decrease in size is correlated with a change in proportions. Understanding the significance of a particular morphology or inte
Comparison of Approaches to a Multimedia Presentation
Two computer-based multimedia lecture presentations were developed using the same software but using two different approaches. Similar lecture material was used for both lecture presentations. Students found that there were considerable differences between the two lecture presentations. One lecture presentation was found to be very dynamic and interesting compared to the other. However, when videos showing applications of theory were supplied with the less interesting lecture presentation, stude
An Introduction to Plant Vascular Systems
As a laboratory exercise that uses scientific techniques to add an investigative component to study the vascular system of plants.
Developing Customized Instructional Software
Costs to faculty in time and costs for the purchase of software help inhibit widespread instructional computing. mpAuthor is an expensive program for DOS/IBM microcomputers; anyone able to use a word processor producing ASCII files can create menu-driven exercises. Several examples of its use are presented, including some to improve thinking and problem- solving skills. Strengths of the program include: minimal computer skills required (have students create exercises instead of a term paper or a
Control of Surface Exudation by Slugs
This experiment is meant to study water regulation in mollusks by observing the reaction of slugs, which are closely related to mollusks, to excess water.
Impact of Computer Aided Learning on Children with Specific Learning Disabilities
The Technology Initiatives Division of Azim Premji Foundation has launched programmes for use of computers in rural schooling. One such programme is Computer Aided Leaning (CAL) that envisages deployment of computers as a media to impact learning competencies and to create an attractive environment in the schools. The state government provides the computers in schools and the Foundation has developed required software content designed to aid classroom learning process in specific areas such as m
ATP deficit in bipopulation tumour cord growth
Simulation of tumor cord growth where conversion of the tumor to glycolytic (anaerobic) metabolism takes place under hypoxia. This video shows evolution of the region where the aerobic cells suffer from hypoxia (ATP deficit) as well as the limit where the glycolytic cells start suffering too. This video reflects work in progress and may be different from the final results.
Crystalluria and its possible significance. A patient-control study.
The significance of crystalluria in the diagnosis and prognosis of urolithiasis remains a controversial subject in the current urological literature. In this study, in addition to the standard urolithiasis clinical and biochemical work-up,routine urine microscopy was performed to study crystals in 1 fresh and 2 stored morning urine samples from 140 urinary stone patients and 42 controls. Crystalluria was more frequently detected in patients (9.3% of the fresh samples)than in controls (2%). Stori

Approaching plays
Do you want to get more out of drama? This unit is designed to develop the analytical skills you need for a more in-depth study of literary plays. You will learn about dialogue, stage directions, blank verse, dramatic structure and conventions and aspects of performance.
Alternative Marcoeconomics
The is the study of how scarce resources are allocated to satisfy unlimited wants in a cultural context. Microeconomics is often defined as the study of individual agents' [persons, organizations, firms, markets] choices about the allocation of scarce goods and how these individual choices relate to the society made up of those individuals. The focus here is the use of technology and social interaction to coordinate individual action.
Human Genome Education
Anyone with a computer and an Internet connection can now explore the draft sequence of the human genome. How can molecular biologists capitalize on these data riches, and what are the advantages of using the assembled draft sequence? This website aims to jump-start those who want make use of this information, but are not sure where or how to start.
Defying Genocide
This collection of activities and resources is a companion guide for the 15-minute film Defying genocide. The history of the Holocaust and the 1994 Rwandan genocide illustrate the entire spectrum of human behavior, from unimaginable evil to extraordinary goodness.
Through a study of the Holocaust, Rwanda, and genocide, students learn that genocide occurs because individuals, organizations, and governments make choices to participate, resist, or turn away.
Students can also see that at the same
Computer Science
Computer science is the study of computational systems and their use in representing important problems in science and society. Major topics include computational science, software systems, network systems, theory of computation, machine learning, and human-computer interaction.
Design and Construction of an Eco-House
This interdisciplinary course is a real-world collaborative multi-year project that connects various departments, courses, and independent study projects on a college campus. Using the client/consultant model, students from several departments and a wide range of environmental backgrounds come together to explore the design of an efficient future student house on campus. Over a couple of years, students research and test building designs, energy for heating and power, natural flows of available
Calibrated Peer Review: Introduction - Why Study Geology?
In this activity, students read an article entitled "Why Study Geology?", then write an essay addressing points listed in the Writing Prompt. After this, students are introduced to the process of Calibrated Peer Review and evaluate their papers. On this Starting Point page, users can access information about the exercise's learning goals, context for use, teaching notes and tips, teaching materials, assessment ideas, references and topics covered.
Digital Durham
For many years scholars have recognized that late nineteenth-century Durham, North Carolina makes an ideal case study for examining emancipation, industrialization, immigration, and urbanization in the context of the New South. "With its tobacco factories, textile mills, black entrepreneurs, and new college," the historian Syd Nathans observes, "Durham was a hub of enterprise and hope." By the early twentieth century, Durham became renowned for its vibrant entrepreneurial spirit. Both W.E.B. Du
How language works - The cognitive science of linguistics
Students studying linguistics and other language sciences for the first time often have misconceptions about what they are about and what they can offer them. They may think that linguists are authorities on what is correct and what is incorrect in a given language. But linguistics is the science of language; it treats language and the ways people use it as phenomena to be studied much as a geologist treats the earth. Linguists want to figure out how language works. They are no more in the busin
Bad blood - A case study of the Tuskegee syphilis project
Syphilis is a venereal disease spread during sexual intercourse. It can also be passed from mother to child during pregnancy. It is caused by a corkscrew-shaped bacterium called a spirochete, Treponema pallidum. This microscopic organism resides in many organs of the body but causes sores or ulcers (called chancres) to appear on the skin of the penis, vagina, mouth, and occasionally in the rectum, or on the tongue, lips, or breast. During sex the bacteria leave the sores of one person and enter
Reading for Philosophical Inquiry
In this introduction to philosophical thinking, we will read some essays specially chosen from four main areas of interest: (1) the philosophy of life, (2) the philosophy of religion, (3) ethics, and (4) metaphysics and theory of knowledge. Although our approach is not comprehensive, it is reasonably representative of some of the more significant areas of philosophical inquiry. The readings are intended to illustrate the interrelations between these subject areas of philosophy and, as well, to p
