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)

Discusses the use of thin-layer chromatography (TLC) in the chemical laboratory as a quantitative method for determining the molecular weights of organic compounds. Describes a simple method which provides an illustration of the importance of polarity on solubility and demonstrates the effectiveness of TLC as a quantitative tool. (TW)

Describes a simple undergraduate experiment in chemistry dealing with the "solvent effects" in nuclear magnetic resonance (NMR) spectroscopy. Stresses the importance of having students learn NMR spectroscopy as a tool in analytical chemistry. (TW)

Describes three situations in which computer software was used in a chemistry laboratory. Discusses interfacing voltage output instruments with Apple II computers and using spreadsheet programs to simulate gas chromatography and analysis of kinetic data. Includes information concerning procedures, hardware, and software used in each situation. (CW)

Presents a laboratory exercise suitable for advanced placement biology or chemistry classes. Discusses the theoretical approach, preparation and standardization of reagents, and results. Emphasizes standard analytical procedure and chelometric titration. (CW)

Describes an experiment designed to use the ability of duckweed to convert the secondary hydroxyl moieties into ketone groups. Discusses the preparation of plant material, materials, procedures, and results for this biotransformation experiment for undergraduate students. (CW)
