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…

Four computer programs written in FORTRAN and BASIC develop theoretical predictions and data reduction for a junior-senior level heat exchanger experiment. Programs may be used at the terminal in the laboratory to check progress of the experiment or may be used in the batch mode for interpretation of final information for a formal report. Several…

This booklet is one of the "Understanding the Atom" Series. Consisting of three sections, it is an account of the development of the first nuclear reactor by a team of scientists led by Enrico Farmi. The first section briefly reviews the early work on nuclear fission and neutron emission, the impact of Einstein's letter to President…

This text is the first volume used in the Intermediate Science Curriculum Study (ISCS) three year junior high school science program. The text is activity-oriented and consists of a series of experiments related to forces, work, energy, friction, electricity, heat, and other areas in physical science. The activities are designed for independent…

This paper describes an experiment designed to reveal the consequences of the development of a concentration boundary layer. The rate of a mass transfer limited electrochemical reaction is measured and used to obtain the dependence of average Sherwood number on Reynolds number and entrance length. (Author/BB)

A high school biology experiment is presented. The success of this experiment may be due to the inability to prove or disprove the hypothesis upon which it is based. (BB)

Discusses the potential use, by students in cell biology and plant physiology, of isolated chloroplasts for determining the Emerson enhancement effect. The experiment designed to measure spectrophotometrically the photoreduction of a dye by illuminating chloroplasts with short- and long-wavelength light is presented. (HM)

Presents a detailed discussion of the "Drinking Duck" toy and its use to illustrate scientific and technical issues in thermodynamics. Numerous illustrations and equations are included. (MA)

The "Getaway Special" is NASA's semiofficial program for low-budget researchers, who can arrange bookings for their own space experiments on regular flights of the space shuttle. Information about arranging for NASA to take individual experiment packages is presented. (LBH)

Science activities or experiments described are: (1) plant cloning, (2) determining the cost-effectiveness of gas and electric heating, and (3) a physics project competition. (MDR)

Proposes an alternative to the classical minimum-deviation method for determining the refractive index of a prism. This new "fixed angle of incidence method" may find applications in research. (Author/GA)

Presents some ideas and demonstrations in college chemistry. (HM)

Describes four cases for which simulation techniques can be used to analyze the kinetics of the chemical system. Included are series first-order and enzyme kinetics. (MA)
