An approach which may be useful for teaching electrochemistry in freshman college chemistry courses is presented. Discussed are the potential problems with teaching this subject and solutions provided by this approach. (CW)

This paper suggests a nontraditional pedagogic approach to the subject of redox reactions and electrode potentials suitable for freshman chemistry. Presented is a method for the representation of galvanic cells without the introduction of the symbology and notation of conventional cell diagrams. (CW)

Described are demonstrations designed to reveal the important "nonsolvent" properties of water through its interaction with a toy called "Magic Sand" and other synthetic silica derivatives, especially those bonded with organic moities. The procedures for seven demonstrations along with a discussion of the effects are presented. (CW)

Described is a 35mm projector demonstration which combines the advantages a highly magnified view of the sample zone as it undergoes dispersion and the ability to show more than a single-line flow injection analysis manifold. Manufacture and use of the slide for demonstration are discussed. (CW)
