Describes experimental procedures to produce magnetic fields with a thermocouple. Provides diagrams showing the apparatus, tables of experiment data, and background information on the theory. (YP)

Describes ways to make use of lab activities and time for effective learning and student motivation. Provides information on the classification of lab activities, class data for measuring student power output, and a sample pre-lab "think sheet" activity. States the importance of relating activities to topics studied. (RT)

Provided are two experiments which deal with the formation of callus and embryos from tissue culture of carrot roots. Outlined are the purpose, materials, procedure, and results for each. (RT)

Introduces an experiment involving the observation of Brownian motion for college students. Describes the apparatus, experimental procedures, data analysis and results, and error analysis. Lists experimental techniques used in the experiment. Provides a circuit diagram, typical data, and graphs. (YP)

Although reports of academic cheating are abundant, there are relatively few papers in the literature that focus on cheating in the context of science courses and even fewer that address dishonest practices, such as "cooking" or fudging data, within the classroom laboratory. This paper briefly reviews the existing literature on academic dishonesty…

Practical classes on protein expression and purification were given to undergraduate biology students enrolled in the elective course "Introduction to Genetic Engineering." The heterologous expression of the green fluorescent protein (GFP)* of "Aequorea victoria" is an interesting system for didactic purposes because it can be viewed easily during…

Presents an investigative sequence of experiments addressed to the topic of photosynthesis. (BR)

This procedure, using polystyrene spheres of specified diameter, renders the Millikan oil drop experiment more accurate than the conventional procedure of the polystyrene spheres, eliminates size estimation error, and removes the guesswork involved in assigning proper index integers to the observed charges. (MLH)

Reported here is a convenient alternative for determining the enantiomeric purity of student resolved alpha-phenylethyl amine using a chiral lanthanide shift reagent. (BB)

This experiment graphically demonstrates a change in the sign of the P-C-H coupling constant between trivalent phosphorus and tetravalent phosphorus. (BB)

This reaction can form the basis of a laboratory experiment for students who have mastered basic spectroscopy. The structure of the product can be assigned from four reasonable possibilities on the basis of the nmr spectrum. (BB)
