Discusses the difficulty of explaining the concept of entropy, and provides exercises, experiments, and discussions concerning entropy. (MLH)

Describes a series of tests that can be carried out to assess air pollution and gives background information about the composition of air and polluting contaminants. (BR)

Describes a variety of experiments and activities such as refractive index by an interference method, Young's third slit, a microscope problem, uses of a hand stroboscope, an acceleration game, an aluminum thermometer, why milk boils over, and others. (BR)

Describes how astrophysics can be a do-it-yourself project within a school boy's budget and background, by giving detailed instruction on equipment construction. In addition, this article describes many experiments to undertake, with the equipment, such as determining color temperature, star spectra, chemical composition and others. (BR)

An approach to teaching biology to mixed ability groups which primarily relies on individualized instruction is described. (BR)
