The Physical and Theoretical Chemistry Laboratory: Oxford University: Chemical and Other Safety Info
Working with chemicals can be very dangerous if properties of the chemicals are not known. This site serves "as a source of general information about the potential hazards of chemicals," but it warns that the Material Safety Data Sheets (MSDS) should always be obtained from the manufacturer. Compiled by the Oxford University chemistry department, the resources given on this site complement MSDS sheets very well. For instance, a brief guide explains how to properly use and interpret them, and a m

Energy Intelligence Agency
An active way for students to find a few critical facts about how we use energy and how much energy we use. Each student has a “clue”, some of which are pertinent energy facts and others are silly statements that are clearly not related. The students ask each other for clues and mingle until they have collected all the facts they need. This provides a more interactive way to communicate energy statistics without a lecture and introduction with board work. The goal is to introduce students to

Micromechnical Biosensors and their Integration with Aptamer-based Receptor Molecules
This site is one of many on \\\\\\\"nanoHUB.org\\\\\\\" which highlights availability of on-line simulations. This particular one provides a video of a research seminar on the topic of micromechanical biosensors focusing on aptamer-based receptor molecules. The quality of the graphics in the video is not high - mainly, the smallness of the visuals makes it difficult to decipher the contents. However, the information content, as delivered and described verbally, is coherent and useful. The i

"Selfish wealth is never good": A Worker's Definition of Success
The ideology of success--the notion that anyone could make it with enough hard work--was widely promoted in Gilded Age America. One of its most famous proponents was the author Horatio Alger, whose novels showed how poor boys could move from "rags to respectability" through "pluck and luck." Between the late 1860s and his death in 1899, Alger published more than 100 of these formulaic stories about poor boys who made good more often because of fortunate accidents than because of hard work and de
