Step by Step Krebs cycle
These pages show the steps of the metabolic pathway called the Tricarboxylic Acid (TCA) cycle. Otherwise known as the citric acid cycle and the Krebs cycle. Data sheets, reaction diagrams and animations are provided for each step. Krebs cycle or the citric acid cycle or tricarboxylic acid cycle,occurs in mitochondria, is the common pathway to completely oxidize fuel molecules which mostly is acetyl CoA ,the product from the oxidative decarboxylation of pyruvate. It enters the cycle and passes
The monosaccharide browser allows you to view space filling Fischer projections of monosaccharides. You can edit the structure and discover the correct name or you can select names from the classified index to discover the structure. The structure can be edited by choosing between aldose/ketose, number of carbon atoms between 3 and 6 and by clicking on carbon atoms to alter chirality. The Monosaccharide Browser can be used as a study aid in various ways. •Make a random monosaccharide by clic
Bat Cave: Underground
ROM Video Producer, Elaisha Stokes, visits Jamaica's St. Clair Cave. A Toronto team from went to Jamaica in January 2010 to gather footage of the inhabitants of the underground structure in preparation of the opening of the new bat cave.
A Beginners Guide to the Study of Plant Structure
This resource contains detailed protocols and instructional information used to conduct an undergraduate laboratory exercise in introductory botany and plant structure. It includes student outlines and instructors notes.
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
Symba: a Framework to Support Collective Activities in an Educational Context
Symba is a Web-based framework designed to support collective activities in a learning context. It has been constructed with a double objective, (1) make students explicitly work out their organization and (2) provide tailorability features to allow the students to decide about the tools and resources they want to be accessible in order to achieve the tasks they have defined. Symba dissociates an organizational level and an activity level. The organization level allows students to organi
New Media and Open and Distance Learning: New challenges for Education in a Knowledge Society
The "digital society" provides not only with new technology, but also with new concepts. Information plays a central role and becomes a valuable good, but knowledge cannot be reduced to information, and one aim for educators is to contribute in a "knowledge society", not only an "information society". A knowledge society is structured in networks, enriching the traditional hierarchies; a knowledge society promotes a kind of "collective intelligence". In such a society, open and distance learning
Historic Pittsburgh, an extensive digital resource created at the University of Pittsburgh, offers both an entry point and substantive classroom resources for teachers of American History at various grade and university levels. This Web site enables access to historic material held by the University of Pittsburgh's University Library System, the Library & Archives at the Heinz History Center, Carnegie Museum of Art, Chatham College Archives, Pittsburgh History & Landmarks Foundation, and Point

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.
Commemoration: Visual texts
This unit explores the commemoration of war through treating two war memorials – the Sandham Memorial Chapel and the Royal Artillery Memorial – as 'visual texts'. By helping you to respond to visual cues the unit aims for you to develop your understanding of these memorials, not only as memorials, but as artefacts or 'made objects'. It does this through consideration of such factors as the location of the monument; its function and purpose; its symbolism or realism; use of materials and over

Using Insects in the Classroom
Insects are an excellent resource for science education. Many insects are easily maintained in the classroom and can happily thrive despite being handled and kept in captivity. The remarkable diversity in form and function of commonly found insects promotes interest and enthusiasm in observing the natural world. Insects can also be used to model a variety of scientific principles. The objectives of this page are to give educators basic information about insects and ideas on how to use insect
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

LSE Literary Festival - How to write a novel- an introduction for beginners with Justine Mann
Does the task of writing a novel both excite and daunt you? Using the political novel as an example, this workshop will examine how to progress from initial ideas to a successful draft. Participants should emerge with an understanding of the task that lies ahead and a greater sense of what is required in terms of structure, characterisation and plot.
