An integrated accessible microscopy workstation was designed and developed to allow persons with mobility impairments to control all aspects of light microscopy with minimal human assistance. This system, named AccessScope, is capable of performing brightfield and fluorescence microscopy, image analysis, and tissue morphometry requisite for…

This experiment was designed to help students improve the critical thinking skills that are required to analyze and discuss the results of an organic chemistry experiment in an effective manner. The initial objective indicated in the prelab handout for this puzzle experiment was the synthesis of methyl 4-bromobenzoate using the Fischer…

An important learning goal of a molecular biology curriculum is the attainment of a certain competence level in experimental design. Currently, undergraduate students are confronted with experimental approaches in textbooks, lectures and laboratory courses. However, most students do not reach a satisfactory level of competence in the designing of…

A single-semester elective combines Mendelian and molecular genetics in a problem-solving format. Students encounter a genetic disease scenario, construct a family pedigree, and try to confirm their medical diagnoses through laboratory experiences. Encouraged to generate ideas as they test their hypotheses, students realize the importance of data…

The question of where the line is often arises as tutors attempt to confine their tutoring within ethical boundaries suggested by the line image. On the surface, some issues look easy. To the question of whether tutors should offer advice on take-home test writing assignments, most writing center personnel would probably respond with…

Describes the program, problems, politics, and exhibits which were encountered in a week long conference. Bibliographies include listings of available papers, curriculum materials, publishers, and equipment manufacturers available upon request. (CP)

A batch distillation apparatus has been designed and built for use in the undergraduate unit operations laboratory course. The column is fully automated and is accompanied by data acquisition and control software. A mixture of 1­-propanol and 2-­propanol is separated in the column, using either a constant distillate rate or constant composition…

Described are several organometallic experiments for the homogeneous hydrogenation of alkenes that could be used in schools. Procedures and expected results are detailed. (RH)

This article briefly discusses some of the dangers involved in the use of radioisotopes and includes a comprehensive list of precautions and laboratory rules for use during radiobiology experiments. (Author)

Eleven practical microbiology books intended or recommended for schools have been evaluated for safety. A number of the texts are unsatisfactory and suggest techniques and, or organisms which are potentially dangerous. (Author)

Describes how to construct a simple bimetallic element and pointer for an overhead projector. The device can be used to demonstrate operation of bimetallic elements. (RH)

The attempts of scientists to detect the existence of the medium of ether are traced. (DT)
