Acid-base titration concepts and experiments are ubiquitous, yet challenging, aspects of the general chemistry curriculum. Most general chemistry courses include at least one acid-base titration laboratory experiment, though the focus is often on determining the concentration, pK[subscript a], or molar mass of an analyte rather than on the details…

A practical focusing on the synthesis, isolation, and hydrolysis of ammonia borane (AB), H[subscript 3]N·BH[subscript 3], was developed for first-year undergraduate students. By requiring students to propose their own experimental setup to measure the amount of gas produced upon hydrolysis, experimental design skills were introduced and developed…

The design and implementation of an advanced guided-inquiry experiment for the organic laboratory is described. Grubbs's second-generation catalyst is used to effect the ring-closing metathesis of diethyl diallylmalonate. The reaction is carried out under an inert atmosphere at room temperature and monitored by argentic TLC. The crude reaction is…

Reports on Westfield State College's Animal Behavior course which requires students to design their own research projects, write a scientific research proposal, conduct experiments, and present results in the form of a scientific paper. (Author/MM)

The National Science Foundation and others have made compelling arguments that research be incorporated into the learning of undergraduates. In response to these arguments, a two-hybrid research project was incorporated into a molecular biology course that contained both a lecture section and a laboratory section. The course was designed around…
