This paper attempts to promote an understanding of physics through its history and replication of the oscillation experiments of Isaac Newton and Daniel Bernoulli from the 17th and 18th centuries. The experiments described can be treated at a level of sophistication to suit the interests and capabilities of the student. Reproductions in the…

These units developed for teacher use consist primarily of a collection of typical experiments or research activities developed by staff and participants of a National Defense Education Act Institute. The institute was designed to broaden the viewpoint of 25 industrial arts teachers with regard to some of the newer scientific and/or engineering…

Presents an experiment for determining the pH of shampoo. (SL)

Describes an experiment to introduce students to qualitative and quantitative aspects of neutron activation analysis. (SL)

Suggests a laboratory introduction to solid-solid phase transitions, thermochromism, and color changes associated with changes in ligand coordination suitable for undergraduate students in physical and general chemistry. Describes the preparation and analysis of the experiment. (CW)

Describes an apparatus that can be used to measure low gas pressures over a range of temperature in the undergraduate teaching laboratory. Discusses an experimental procedure and theory for pressure temperature measurements with this apparatus. (CW)

To improve the testing of students' skills in performing laboratory experiments, 92 Israeli high school physics teachers participated in the development of a list of weighted laboratory skills. Sensory-motor coordination was found to be a significant measured factor. Factors affecting reliability were also noted. (GDC)

Cites reasons why Penicillium claviforme is an exceptionally good species for ultraviolet induced mutation experiments. Provides a set of laboratory instructions for teachers and students. Includes a discussion section. (ML)

Presents a laboratory experiment which determines critical temperature and density of carbon dioxide. Discusses critical point and provides equations to estimate liquid volume fraction. Analyzes experimental results in terms of variables. (JM)

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)

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)

Described is a procedure for the study of condensation polymerisation. The objectives of this study are to help students understand concepts that are somewhat abstract in nature (i.e., polymerisation) through derivation of equations that help to describe and predict the particular phenomena. (CS)

Presents an experiment involving photochemical legand displacement on a metal carbonyl, separation of the product mixture by chromotography, and identification of the components by use of infrared spectroscopy and group theory. The chromatography and spectroscopy are combined as complementary tools in this experiment. (Author/JN)

Describes a laboratory experiment which demonstrates manipulation of highly reactive chemicals, use of a gas trap, and simple and reduced pressure distillation. Student must characterize starting material and product with nuclear magnetic resonance and infrared spectroscopy. (Author/SA)

Presents information intended to encourage students to become thoughtful consumers. Discusses the role of pepsin in splitting off amino acids from stomach proteins and the nature of the protein substrate in determining the ph at which pepsin operates. Directions for an experiment are included. (Author/SA)
