A laboratory study is detailed utilizing the skills of hypothesizing, designing experiments, and controlling variables. (EB)

Described is the construction of a density gradient column and several density related experiments which can be performed with the device. (SL)

Discusses the development of single concept or skill laboratory investigations in an inservice summer workshop and their successful use in the classroom. Included are two examples, respectively, relating to operation of a triple beam balance and classification of phases of matter. (CC)

Describes the laboratory procedures for the measurement of thermal expansion and viscosity of liquids. These experiments require inexpensive equipment and are suitable for secondary school physical science classes. (JR)

Discusses the design of two experiments on the reactions of 1-Chloro-1, 2-diphenylethane and of C-5 halides with nucleophiles in an inservice teacher course. Indicates that the material can be applied in teaching chemistry at both secondary and college levels. (CC)

Presents a list of topics, research areas, references, and laboratory equipment which is prepared to facilitate general-science students' understanding of physics aspects in accelerated reference frames after their study of circular motion and Galilean relativity in mechanics. (CC)

Describes an experiment which yields low-volatility phenylacetylene, and suggests the use of the liquid product to examine alkyne chemical reactivity in organic chemistry courses. (CC)

Describes the conduct of a self-contained course designed for biology, chemistry, and physics majors, particularly liberal arts seniors, with introductory physics and biology or chemistry as its prerequisites. (CC)

Describes a variety of experiments that can be performed using the disposable syringe. Among others, these include the removal of oxygen during rusting, convection in a liquid and in air, gas collection in an electrolysis cell, small scale production of a fog, and hydrogen/oxygen extraction from a voltameter. (JR)

Describes a five-week introductory medical science course designed for both science and nonscience majors through integration of physiology, organic chemistry, anatomy, and biochemistry.
