Describes experiments on the properties of bile salts in teaching physical chemistry for biologists. (SL)

Describes an experiment using an analog computer which allows students to work with familiar problems, and to program the computers themselves. (SL)

Describes an experiment to distinguish aldehydes from ketones utilizing a recently introduced reagent. (SL)

Describes a three period project type laboratory experiment designed to maintain student interest. (SL)

Suggests ways in which hens' egg vitelline membranes can be used to demonstrate cell traction effects. Reviews procedures for using and culturing the membranes and identifies topic areas for student projects. (ML)

The goal of many colleges is to make the organic chemistry laboratory completely flameless by using electric heating equipment. Benefits of eliminating the Bunsen burner, electrical heating equipment and accessories, hazards remaining in flameless laboratories, and design standards related to laboratory liability are the major topic areas…

Describes a chemistry program in which experiments are performed for students in grades one to three. The experiments use only materials and apparatus found in the average home so they can be reported by teachers or parents. Students become involved in the program by asking questions and making predictions. (JN)

Describes an interdisciplinary chemistry course at the New Jersey Institute of Technology (NJIT) in which at least one quarter of the time is devoted to materials science. Includes information on course content, laboratory work, and assessment of student performance on chemistry and materials science topics. (JN)

Outlines a simple method which shows the relation between work done in accelerating a mass and the resulting velocity of the mass. Equipment used includes a rubber ball, ramp of lumber, graph-chart, stopwatch, and hand calculator. (DH)

Discusses modifications and special equipment needed by wheelchair-bound students for 33 common freshman physics experiments. Physical adjustments, individual needs, and personnel are addressed, with emphasis on building a rapport to learn what a student can and cannot do. A list of modifications for specific experiments (by topic) is included.…

Reviews three experiments which can be used to introduce microscale techniques. Highlights the benefits and advantages of having undergraduate students prepare and purify derivatives on the small scale. (ML)

Presents three demonstrations suitable for undergraduate chemistry classes. Focuses on experiments with calcium carbide, the induction by iron of the oxidation of iodide by dichromate, and the classical iodine clock reaction. (ML)

Presents a laboratory exercise that illustrates stoichiometry, limiting reagents, and proportionality. Highlights the safety and low cost factors of this exercise. Outlines procedures for the students. (ML)

Provides background information on the equipment and knowledge necessary to do an astronomy activity on the earth's rotation. Details an activity in which students can measure the rotation of the earth using a camera and the stars. (CW)

Describes how short-term laboratory projects were used to teach population and community ecology to undergraduate environmental science students. Directed students to formulate and implement their own hypotheses and experimental designs. Uses questionnaire results and written reports to assess the contribution of the course to student…
