This article reports the adoption of new policies to restrict experiments on animals in the elementary or secondary school classroom. The controversy involving animal welfare groups is discussed as it relates to animal abuse by students. (SA)

Data are presented from a Canadian study to show that the cost of laboratory testing is escalating and represents a sizable proportion of hospital costs. Policy interventions will require thorough analysis and will require sophisticated control programs at various levels in the laboratory inquiry system. (Author/MLW)

Describes method for locating images in simple and complex systems of thin lenses and spherical mirrors. The method helps students to understand differences between real and virtual images. It is helpful in discussing the human eye and the correction of imperfect vision by the use of glasses. (Author/SK)

Describes an exercise involving the use of kinematics to decide if one should stop or try and get through an intersection when the traffic light turns yellow. Gives students' experience in recording data, doing simple calculations and connecting classroom studies to real world experiences. (Author/SK)

Briefly describes some experiments which give indications that neutrinos may not be massless particles. (SK)

Describes the features of various computer chemistry programs. Utilization of computer graphics, color, digital imaging, and other innovations are discussed in programs including those which aid in the identification of unknowns, predict whether chemical reactions are feasible, and predict the biological activity of xenobiotic compounds. (CS)

Describes the use of a microcomputer in studying a model experiment (Brownian particles colliding with thermal particles). A flow chart and program for the experiment are provided. Suggests that this experiment may foster a deepened understanding through mutual dialog between the student and computer. (SK)

Presents the procedures involved in conducting a photochemical experiment intended to provide undergraduates with exposure to the synthetic advantages of organic photochemistry. (Author/SA)

Describes the process dynamics and control program developed by the chemical engineering department at the University of California, Santa Barbara. Undergraduate and graduate control courses and real-time computing courses are included. (HM)

Presents seven selected biology notes which could be used in the school biology courses. Each includes the name of the author and a description of activities suggested. (HM)

Describes a technique for the laboratory culture of Eucyclops agilis using Euglena. Details of the life cycle are given, and suggestions for its use in laboratory practicals, and in investigations with sixth-form (16 to 18 year-olds) and college students in the United Kingdom. (Author/HM)

Describes a laboratory demonstration in chemical equilibrium using ferric chloride and ammonium thiocyanate that would serve as a useful basis for an inquiry investigation. (BT)

Describes a programed, independent study, college level, general chemistry course designed to develop good technical laboratory skills with no attempt made to relate laboratory experiments and classroom topics. A list of experiments used and a sample laboratory examination are included. (BT)

Described is a base-friction modeling technique for studying the development of collapse structures in jointed rocks. A moving belt beneath weak material is designed to simulate gravity. A description is given of the model frame construction. (Author/SA)

An experiment for senior college undergraduate physics students is described. Amorphous tungsten trioxide films are suggested for use since they have a unique electrochromic system. (Author/SA)
