Students collected and organized data concerning noise levels of various school activities. They reported that the activities were interesting and relevant. (SD)

This freshman chemistry lab relates stoichiometric problems to real situations. It requires students to measure the Fe impurity in reagent grade calcium chloride. (BB)

This experiment provides an excellent practical application of computer-controlled spectrometers. (BB)

Investigates the effectiveness of guided inquiry laboratories for the first semester general chemistry course for science majors at the University of Oklahoma, Norman, Oklahoma. The focus is on three skills: data interpretation, hypothesis formation and the experimental testing of hypotheses. (HM)

In this experiment, the observation that, for meta- and para-substituted styrene derivatives, the magnitude of the C-13 shielding value for the beta-carbon is linearly related to sigma for the ring substituent is used to determine sigma. (BB)

In one option for this project, the rotation-vibration infrared spectra of a number of gaseous diatomic molecules were recorded, from which the fundamental vibrational wavenumber, the force constant, the rotation-vibration interaction constant, the equilibrium rotational constant, and the equilibrium internuclear distance were determined.…

Presents the following chemistry lecture demonstrations and experiments: (1) a versatile kinetic demonstration; (2) the Bakelite Demonstration; (3) applying Beer's law; and (4) entropy calculations. (HM)

Presents a formulations laboratory project in which secondary school students attempt to prepare a common household product from laboratory chemicals. (HM)

Video cassette demonstrations are useful in teaching experimental techniques and instrumentation. This article describes how the recorded demonstrations save instructor and student time, how they can be integrated into a multimedia teaching format, and how recordings support student independence. (Author/BB)

A detailed and up-to-date description of how the Harbor Hill Elementary School mathematics laboratory operates is given along with a list of materials that are available in the laboratory. (MN)

A consumer science course at Rumford (Maine) Junior High School uses resources and facilities of the home economics and science departments to take low-ability students through a variety of practical learning experiences combining chemistry, biology, and home economics. Rotation of classrooms and teachers helps to keep the students interested. (MF)

Describes four science laboratory, consumer oriented activities including: milk, fireproofing clothing, acetic acid, and paints. (SL)

A home economics classroom designed to conserve energy and encourage students to practice a simpler life-style is described, and a check list of forty-five suggestions for developing the home economics laboratory as an environmental model is presented. (BM)

Describes an experiment which demonstrates the association of particular metabolic biochemical changes and muscular fatigue. Highlights applications related to cellular energy metabolism, metabolic regulation, and muscle energetics. (ML)

Aspects of laboratory preparation necessary for undergraduate or graduate optometric training in the use of therapeutic drugs are discussed, including glaucoma therapy, anterior segment techniques, posterior segment, and systemic procedures. (MSE)
