An applied science course with a variety of activities and independent studies for unmotivated high school students is described. (SA)

Describes a type of individual laboratory-activity examination developed for use in an undergraduate general physics class whose enrollment was more than 100 persons. Test preparation, procedure, evaluation, and outcomes are discussed. (BT)

Presents two demonstrations which are intended for chemistry college students. These demonstrations are: (1) enhancement of concentration quenching by micelles; and (2) the thermite lecture demonstration. (HM)

Describes the collection, care, and maintenance of protozoa by elementary school students. Techniques for collecting and observing them are given. (SA)

An inorganic chemistry course at the Free University of Amsterdam is part of an integrated program involving practical work and theoretical study for chemistry students. Twelve experiments are required and 11 are performed by students in groups of fours. (Author/SA)

Describes the use of cassette tape recordings in preparing freshman chemistry students for experiments in laboratories. The tapes are said to have decreased student anxiety in the laboratory and increased laboratory skills. (SA)

Describes how to measure Brewster's angle using Polaroid sunglasses and the reflection of the ceiling light on a polished floor. (GA)

In this experiment, the student duplicates the experiment reported by Wohler in 1828. (BB)

In this experiment, benzylic hydrogen reactivity is used to prepare dimers of a variety of alkyl benzenes, and the benzylic hydrogen reactivity of these compounds are compared. (BB)

This simple two-phase procedure for the oxidation of secondary alcohols to ketones is applicable to a wide variety of substrates and is also ideally suited for the undergraduate laboratory. (BB)

Describes a titration procedure done in glacial acetic acid. (BB)

Describes a college level introductory oceanography course that incorporates a hands-on laboratory component. The activities include the determination of density and buoyancy, light transmission in sea water, and wave refraction. (MA)

Diagrams and explains construction of an actograph which quantitatively records daily movements of animals for a 24-hour period. Combines use of a kymograph and the teetering box of Palmer. Biorhythm activities with fiddler crabs, cockroaches, and hamsters are suggested. (CS)

A mathematics laboratory approach used with hearing-impaired junior high youngsters is described and discussed. (DT)

Preliminary evaluations of the University of Florida's pharmacy practicum-internship program cover: (1) the interns' subjective evaluations of their experiences; (2) the preceptor's subjective evaluation of interns' performance over two years; and (3) objective measurements of student competencies.
