Uses a vortex device as a model to study low-pressure systems and other related investigations. (LS)

Describes a general chemistry level kinetics experiment requiring three 3-hour laboratory periods. Data analyses can be accomplished with graphical techniques or a non-linear least squares computer program. (MLH)

Describes a computer simulation experiment in which physical chemistry students can determine all of the kinetic parameters of a reaction, such as order of the reaction with respect to each reagent, forward and reverse rate constants for the overall reaction, and forward and reverse activation energies. (MLH)

Describes an experiment in which general and physical chemistry students can determine the heat of vaporization of a volatile substance from experimental laboratory data using timesharing techniques. (MLH)

Illustrates a safe and easy way of igniting a hydrogen-oxygen mixture and lists the equipment used. (BR)

Describes how you can lead students to erroneous inferences and conclusions by using demonstrations which point out to students the importance of carefully distinguishing between observations and inferences. (BR)

Describes the inexpensive construction of an uptake volume potometer uptake and loss potometer, and experiments on plants that can be conducted with the equipment. (BR)

Describes a science program for the mentally retarded institutionalized adult. Raises questions concerning the practicality of science exposure in lieu of or in addition to vocational training. (BR)

A reaction kinetics experiment for the chemical engineering undergraduate laboratory course was developed in which in-situ Fourier Transfer Infrared spectroscopy was used to measure reactant and product concentrations. The kinetics of the hydrolysis of acetic anhydride was determined by experiments carried out in a batch reactor. The results…

The demonstration of a simple viscosity experiment for high school classes was conducted and assessed. The purpose of the demonstration was to elicit the interest of high school juniors and seniors in the field of chemical engineering. The demonstration consisted of a discussion on both engineering and the concept of viscosity as well as a…

This paper describes the way in which the University of Lowell Instructional Network is being used to provide local schools with access to the university's facilities and faculty. The STAR (Science Teachers Accessing Resources) program is described in detail from its inception, through the planning stages, culminating in two-way television…

The history of the National Aeronautics and Space Administration Skylab program is provided in this three-part book. Part I (chapters 1 to 5) traces the origins of the Skylab concept from its emergence in the period 1962-65 through its evolution into final form in 1969. Part II (chapters 6 to 13) focuses on the period from 1969-73, considering the…

Nine lessons which involve the use of marine organisms in the classroom are presented in this seventh-grade biology unit. The unit offers instructors alternative ways of meeting common life science goals. It is not meant to be an extra curriculum added to the normal course load, but was developed to consolidate a group of activities designed for…

This 2-3 week high school chemistry unit is designed to provide students with an awareness of Gasohol as an energy alternative. Gasohol is a blend of 10 percent pure ethanol and 90 percent unleaded gasoline. The unit consists of nine activities (five laboratory experiments, three informational readings, and a sample problem activity). The five…

Investigations in Natural Science is a program in secondary school biology, chemistry, and physics based upon the description of science as a quest for knowledge, not the knowledge itself. This teaching guide is designed for use with the 19 chemistry investigations found in the student manual. These investigations focus on concepts related to:…
