A course to provide a common introductory experience for both majors and non-majors is described. The topics and concepts taught in the quantum mechanics segment of the course are discussed. (DT)

Eight laboratory exercises are described which involve the protein properties of hemoglobin, and six experiments are outlined which involve hemoglobin as a metalloprotein. (DT)

Procedures and discussion of an experiment to be used in an undergraduate course in spectroscopy are presented. The experiment involves the measurement of the absorption spectrum of sodium vapor. (DT)

The role of spectral color slides in laboratory situations is discussed, then experiments for secondary school students concerning color and wave length, evidence of quantization, and the ionization energy of the hydrogen atom are outlined. Teaching guidelines for creating a set of spectrograms and photographic specifications are provided. (DT)

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)

By concentrating radioactivity contained on luminous dials, a teacher can make a high reading source for classroom experiments on radiation. The preparation of the source and its uses are described. (DT)
