Energy John W. Moore
Scientific Challenges in Sustainable Energy Technology, by Nathan S. Lewis of the California Institute of Technology, summarizes data on energy resources and analyses the implications for human society. Slides, text, and streaming audio/video are available at his Web site. There is much in this presentation that could (and should) be incorporated into chemistry pedagogy.

Job's Analysis of the Range of the "Dalton Syringe Rocket" Natalie Barto, Brandon Henrie, and Ed Vitz
An apparatus for safely igniting fuel gas/oxygen mixtures in a syringe and measuring the distance that the syringe is propelled is presented. The distance (range) is analyzed by the method of continuous variation (Job's Method) to determine the stoichiometry of the reaction.

Entropy, Disorder, and Freezing Brian B. Laird
It is argued that the usual view that entropy is a measure of "disorder" is problematic and that there exist systems at high density, for which packing considerations dominate, where a spatially ordered state has a higher entropy than a disordered one.

Shuffled Cards, Messy Desks, and Disorderly Dorm Rooms - Examples of Entropy Increase? Nonsense! Frank L. Lambert
Simply changing the location of everyday macro objects from an arrangement that we commonly judge as orderly to one that appears disorderly is a "zero change" in the thermodynamic entropy of the objects because the number of accessible energetic microstates in any of them has not been changed.

Why Don't Things Go Wrong More Often? Activation Energies: Maxwell's Angels, Obstacles to Murphy's Law Frank L. Lambert
The micro-complexity of fracturing utilitarian or beautiful objects prevents assigning a characteristic activation energy even to chemically identical artifacts. Nevertheless, a qualitative EACT SOLID can be developed. Its surmounting is correlated with the radical drop in human valuation of an object when it is broken.

The conversion of chemical energy: Part 1. Technological examples Wink, Donald J.
When a chemical reaction occurs, the energy of the chemical species may change and energy can be released or absorbed from the surroundings. This can involve the exchange of chemical energy with another kind of energy or with another chemical system.
