Describes two experiments for a sophomore level organic chemistry utilizing commercially available borane-methyl sulfide (BMS). (SL)

Presented is an exercise in the ability to navigate by the stars. It applies difficult concepts of positional astronomy concerning coordinate systems and time. Stereographic projection is utilized because it allows rapid completion of calculations and measurements and keeps the concepts clear to the students. (MA)

Presents basic theory of silicon solar cells and discusses their use in experiments in undergraduate teaching laboratories. (SL)

Describes experiments in the measurement of resonances in a nuclear reaction and the measurement of elastic scattering cross section. (SL)

Presents a quantum mechanical model of the ionic solid, lithium hydride. (SL)

Reviews the SDS-polyacrylamide gel electrophoresis technique for the separation of proteins and determination of their molecular weights. (SL)

Presents a systematic approach to reviewing carbon-carbon reactions in an advanced organic chemistry course. (SL)

Presents the outline of an organic polymer chemistry short course, 3-4 weeks. (SL)

Presents a laboratory project in which students analyze quantitatively organic and inorganic industrial waste. (SL)

Presents a biochemistry laboratory experiment in enzymology using polyphenoloxidase or tyrosinase. (SL)

Using a very simple computer program written in BASIC, a very large number of random-generated DNA or RNA sequences are obtained. Students use these sequences to predict complementary sequences and translational products, evaluate base compositions, determine frequencies of particular triplet codons, and suggest possible secondary structures.…

Illustrates that a view of the nature of science is dependent upon underlying assumptions concerning scientific proof. Compares the inductive view of science with the non-inductive viewpoint of Karl Popper. (CP)

Discusses what evaluation is and presents a theoretical framework for planning and conducting educational evaluation. Also includes an extensive annotated bibliography. (SL)

Describes a technique for illustrating basic chemical engineering skills in reactor design and process analysis. (SL)

Reports on adverse side effects in an organic chemistry course taught by the Personalized System of Instruction (PSI). (SL)
