This booklet is one of a set of five booklets which comprise the basic curriculum for "Mathematics Laboratories for Disadvantaged Students," a nationally validated Title III ESEA project. This publication provides evaluation materials and student materials related to number theory. Topics included in this booklet are prime and composite…

A collection of materials to aid cosmetology teachers in organizing and managing laboratory/classrooms is presented in the document. The materials may be adapted for use in a variety of situations and have been compiled by a group of cosmetology instructors. Materials are presented in two ways, with the first providing a discussion of topics which…

As part of an experiment, a three quarter sequence in organic chemistry was designed to be accompanied by laboratory experiments that reinforce the lecture material and encourage independent investigation by minimizing cookbook-style procedures. By having laboratory techniques explained in detail on video casettes, students were exposed to uniform…

Students of advanced life science courses at Beverly Hills High School, California, are able to approximate a wide variety of life process experiments through use of computer simulations. Students are taught to use the BASIC language and to execute programs on the Hewlett-Packard 2000 Access series. Computer programs are used to enhance…

Outlines five simple and inexpensive methods for students to use in identifying unknown substances. Provides a table of general solubility data for ions, a suggested list of unknown substances that can be tested using the methods described, and some prelaboratory information. (TW)

Focuses on the development of a pilot unit for use in an advanced separations process laboratory in an effort to develop experiments on such processes as reverse osmosis, ultrafiltration, adsorption, and chromatography. Discusses reverse osmosis principles, the experimental system design, and some experimental studies. (TW)

Discusses some interesting kitchen chemistry experiments. Describes the use of baking aerators and baking powders in an inexpensive experiment. Outlines several demonstrations to follow up the experiment and to illustrate other chemical principles. (TW)

Describes two demonstrations for use in chemistry instruction. The first illustrates the preparation of a less common oxide of iron, showing why this oxide is rare. The second is an explosion reaction of hydrogen and oxygen that is recommended for use as an attention-getting device. (TW)

Presents 31 science activities for use with high school or college science classes. Topics included are: chromatography, ecology, invertebrates, enzymes, genetics, botany, creep, crystals, diffusion, computer interfaces, acid rain, teaching techniques, chemical reactions, waves, electric fields, rainbows, electricity, magnetic fields, and a Pitot…

Gives a review of four software packages including "Science Toolkit: Module 3--Body Lab" for measuring heart rate, lung capacity, and response time; "Project Zoo: Adventures with Charts and Graphs" for developing process skills; "The Body Electric" for explaining electrical activity in the body; and "M-ss-ng…

This article gives a brief description of the process of the removal of corrosion and millscale from the surfaces of ferrous metals by acid pickling. It suggests an experiment to illustrate this process including the procedure and a discussion of the results. (CW)

Describes an experiment that provides a fundamental understanding of the kinetics of the enzyme papain. Discusses background, materials, procedures and results. Mentions analogous experiments that can be conducted with enzymatic contact-lens cleaning solutions. (CW)

Described is a microcomputer with two detection systems to enable three variables of the puck's motion to be recorded simultaneously: speed, radius of the orbit, and the ongoing time of measurement. Presented are the experimental setup, a discussion of the computer program, and results. (YP)

Describes how to make a superconducting pellet for classroom use. Details two tests that can use the pellet to demonstrate superconductivity. Discusses some of the mechanics and chemistry of superconductivity. Lists materiads and equipment necessary for these activities. (CW)

Announces the incorporation of a laboratory information management system (LIMS) into the academic environment. Describes the applications of a computer-automated laboratory system at one university. Stresses the benefits to students of the use of such a system in terms of entry into the industrial environment and to professors in grading. (CW)
