Suggests kinetic sculpture as a way to provide meaningful experiences with new materials and concepts for high school art students. (GB)

Describes a set of experiments for an undergraduate laboratory which demonstrates the relationship between velocity, mass, and temperature in a gas. The experimental method involves time-of-flight measurements on atoms excited to metastable states by electron impact. Effects resulting from recoil in the electron-atom collision can also be…

Delineates between steady state and equilibrium assumptions, demonstrating the importance of making the equilibrium assumption at the appropriate step in the calculation. Indicates that, for an ozone system, concentrations predicted by these assumptions are different, and depending on the progress of each reaction, can be far from the exact…
