Describes the components of the writing course at York College of the City University of New York, focusing particularly on the writing laboratory with its self-instructional methods and its 13 modules on grammatical features. (RL)

A classroom technique for projecting microorganisms on a TV screen is described. Instructions are given with a step-by-step approach and effective subject matter is suggested. (SA)

Describes a convenient, inexpensive experiment in enzyme kinetics developed for the undergraduate biochemistry laboratory at the University of Virginia. Required are a single beam visible spectrophotometer with output to a recorder, a constant temperature, a commercially available enzyme, substrates, and buffers. (BT)

Describes the five language programs at a Toronto high school. (RL)

Describes a physical chemistry experiment that allows students to test the effect of ionic strength on the rates of a reaction between ions. The reduction of hexacyanoferrate III by ascorbic acid is detailed. Comparisons with the iodine clock reaction are made. (CS)

The synthesis of 1,4-diphenylbutadiene by means of the Wittig reaction is presented as suitable for organic chemistry students at the end of a basic laboratory program to apply laboratory skills and display understanding of the use of phase transfer catalysis and its application in syntheses. (CS)

Comments from the Environmental Protection Agency (EPA) concerning three recommendations (in an article in a previous issue of this journal about inspecting schools for asbestos-containing materials) that are in direct conflict with those offered by EPA. (MLF)

Presents guidelines for the preparation of language teachers planning to use a language laboratory. (AM)

Land between the Lakes, the nation's only federal demonstration area in outdoor education, environmental education, and resource management, provides both recreational facilities for the public and outdoor educational training for college students. Article describes programs, facilities, and objectives of the 170,000 acre "university of the…

An experiment is described in which undergraduate students can optimize the relative yield of sec-butylbenzene by varying molar ratio and temperature. (Author/SA)

Included is information regarding: student construction of Newton's Discs to demonstrate color and of paper helicopters to encourage inquiry; improvising an apparatus demonstrating pressure between two bubbles; animal behavior experiments involving woodlice; two experiments using electronics freezer spray; chromatography of dyes; leaf keys; an…

Presents Part II of a description of a computer-oriented course on process control which has been offered at the University of Wisconsin for undergraduate students. Lecture topics and laboratory experiments are also included. (HM)

Describes briefly three experiments, which are presented by three physics teachers to share their ideas with other teachers and readers. These experiments are: (1) a simple hazemeter for window pollution assessment; (2) the speed of light; and (3) the ball-bearing electric motor. (HM)

This experiment is designed to acquaint the student with a macromolecular synthesis of a crown ether type compound. The starting materials are readily available and the product, a cyclic polyether, belongs to a class of compounds that has aroused the interest of chemist and biologist alike. (Author/BB)

This undergraduate experiment shows that the inclusion of an appropriate additive can have a very marked effect on the physical properties of a polymer. The polymer used is polypropylene and the additives are 2-hydroxy-4-octyloxy-benzophenone and benzophenone. (BB)
