Discusses the general design and operation of a quantitative analysis laboratory which is relevant to the student's career objectives and provides reliable and objective criteria for judging student performance. Included are a list of core experiments and a description of student responses. (CC)

Presents a series of activities which focus on the study of the physical characteristics of water, including temperatures, opacity, pH-values, oxygen concentrations, reagents, and free CO2 concentrations. Indicates that ponds can provide the students with opportunities to learn chemistry, geology, biology, botany, and the effects of weather. (CC)

This booklet of experiments was compiled from various teachers' guides in response to the many requests from students for help in preparing smoking demonstrations and exhibits. The booklet is divided into three sections. Part 1 illustrates a number of experiments, most of which require some laboratory equipment. Part 2 includes a number of…

Describes an experiment in which rat adipose tissue samples are exposed to labeled glucose; insulin is added to one sample. Subsequent scintillation counting demonstrates the ability of insulin to facilitate the entry of glucose into the tissue. (MLH)

In this simple experiment for an undergraduate laboratory a laser beam is passed through the mixing zone of two liquids with different refractive indices. The spatial variation of the refractive index, at different times during the mixing, can be determined from the observed deflection of the beam. (Author)

Describes four synthesis experiments, adapted for the general chemistry laboratory, in which compounds in unusual oxidation are prepared. The abnormal oxidation states involved in the synthesis products are: silver (II), chromium (II), lead (IV), and bromine (I). (MLH)

Describes two experiments, one involving the electrolysis of potassium iodide and the other involving a diffusion process in solid copper. (GS)

Describes an open-ended experiment involving a bioinorganic system that provides the student a direct link between thermodynamics and kinetics. It utilizes a rapid reaction technique and requires one to clearly understand the relationship of experimental observable (absorbance) to a mechanism. (GS)

Presents an experiment in which a programmable calculator is employed as a data generating system for simulated laboratory experiments. The example used as an illustration is a simulated conductimetric titration of an aqueous solution of HC1 with an aqueous solution of NaOH. (Author/EB)

Describes the construction of a calorimeter to be used in an experiment which consists of measuring the rate at which ground level solar radiation raises the temperature of the metal in the calorimeter. (GS)

Explains two approaches for stimulating the intellectual development of the student from the concrete to formal operations level. One method involves experimentation and critique during which the student deduces the principle. The second involves a lecture approach that utilizes the creation of the discrepant event. (GS)
