Traces the evolution of a self-paced organic chemistry course over a three-year period by outlining the reasons behind the important changes that were made and assessing their effects. (MLH)

Describes a one-quarter course in analytical chemistry in which the student performs a variety of analytical methods on the same soil sample. (MLH)

Describes the construction of a versatile signal generator suitable for use in cyclic voltammetric experiments, which can also be adapted to a conventional dc polarograph by replacing its ramp source. (MLH)

Discusses a special topics biochemistry course that uses membrance phenomena to illustrate the interplay of many physical chemistry principles. (MLH)

Discusses the thermodynamics and kinetics of cycloamylose complexation and the use of cycloamyloses to illustrate enzyme active site and spectroscopic studies. (MLH)

Discusses Bohr's atomic theory from a chemical, rather than a physical, standpoint. (MLH)

Discusses Alfred Stock's boron hydride research and his role in the development of organometallic chemistry. (MLH)

Discusses the reasons why molecules for which two or more canonical structures can be drawn are more stable than those for which only one structure can be drawn. (MLH)

Discusses the Donnan Effect by considering three possible cases of membrane equilibrium. (MLH)

Presents graphs that can be used to illustrate the concepts of buffer capacity and acid-base titrations. (MLH)

Describes a chemistry course for electrical engineers that uses oral assessment as a terminal assessment method. (MLH)

Presents a graphical method for evaluating complex equilibrium equations representing the solubility of protolyzable salts. (MLH)

Describes a laboratory experiment that uses a programmable calculator and the concepts of activity and activity coefficients to examine the effect of ionic strength on equilibrium constants. (LH)

Describes demonstrations of the ring strain inherent in cyclopropanes and cyclobutanes and their resultant high reactivity, and selective solubility principles. (MLH)

Describes plastic, skeletal molecular models that are color-coded and can illustrate both the conformation and overall shape of small molecules. They can also be converted to space-filling counterparts by the additions of color-coded polystyrene spheres. (MLH)
