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)

The materials needed and the procedures for construction of the apparatus are detailed. Two experiments that use this equipment are suggested. Criteria for operation are listed. (CW)

Proposed is a more didactic version of the electronic periodic table than is being used. The background and use of the numeric system is detailed and illustrated. (CW)

Reviewed are 15 methods for fast slide production. Methods are classified as in-hand methods and farmed-out methods of slide production. Slides are compared to transparencies as another fast presentation aid. (CW)

The advantages of microchemistry in terms of economics and safety are discussed. A list of six companies known to supply apparatus and reagents for microscale experimentation is provided. (CW)

The materials needed and the procedures used in three microscale chemical laboratory experiments are detailed. Included are a microscale organic synthesis, a two-step synthetic sequence for the microscale organic laboratory, and a small-scale equilibrium experiment. (CW)

Described is a microscale organic chemistry experiment which demonstrates one feasible route in preparing ortho-substituted benzoic acids and provides an example of nucleophilic aromatic substitution chemistry. Experimental procedures and instructor notes for this activity are provided. (CW)

Described is an experiment which is designed to investigate the reaction of the protein ferrimyoglobin with fluoride. The activity uses readily available apparatus and the technique of optical absorbance for measurement of concentrations. Experimental design, procedures, and treatment of the equilibrium data are detailed. (CW)
