Describes a set of biochemistry laboratory experiments in which tetrameric hemoglobin is separated into its subunits then formed again by recombination of the subunits. (MLH)

Explains the techniques of experimenting with the protozoan Colpoda cucullus to learn about its habitats, dispersal and adaptations. (LS)

Describes an experiment that gives useful insight into ideas of solvation and polarity of solvents. (GS)

Experience in using a user-friendly software, Mathcad, in the undergraduate chemical reaction engineering course is discussed. Example problems considered for illustration deal with simultaneous solution of linear algebraic equations (kinetic parameter estimation), nonlinear algebraic equations (equilibrium calculations for multiple reactions and…

Describes teaching schemes and apparatus designed to give the teacher and the student a range of reliable, workable experiments to explore the world of small static charges. (GS)

The design of a freshman chemistry laboratory program involving nontraditional qualitative investigations of metal ion properties is explained. Experiments are discussed which focus on synthesis of a metal salt, properties of metal ions and their separations, and oxidation states of metals. (DT)
