Presents ideas from readers on techniques and equipment that might be useful in teaching secondary school science. Suggests how to construct cheap wall charts, modify a vacuum cleaner into a blower, construct a stereo microscope lamp holder, and outlines simple physics laboratory experiments. (JR)

Discusses the radioactive waste management in Belgium, Canada, France, Germany, India, Italy, Japan, the United Kingdom, the United States, and the USSR. Indicates that scientists and statesmen should look beyond their own lifetimes into future centuries and millennia to conduct long-range plans essential to protection of future generations. (CC)

At Harvard, physics courses are divided into units that the students can master at their own pace and that offer more student-teacher contact and personal attention. (PG)

Discusses three possible methods of thinking about the implications of the definitions of the Avogadro constant and number. Indicates that there is only one way to arrive at a simple and standard conclusion. (CC)

Develops a simplified electrostatic model of the heart with conduction within the torso neglected to relate electrocardiogram patterns to the charge distribution within the myocardium. Suggests its application to explanation of Coulomb's law in general physics. (CC)

Describes an experiment suitable for high school physics classes in which students determine the wavelength of electromagnetic radiation of u.h.f. television transmissions. Elaborate equipment is not required, and details are given for the construction of a dipole. (JR)

Discusses the development of a model for implementing Project Physics without the use of physics teachers. Indicates that students can study Unit 3, independently, with the aid of the supplementary materials produced in this project and achieve as well as the average student in a teacher-taught class. (CC)

Summarizes major findings of the Harvard Project Physics research and evaluation activity, including data gathering techniques, descriptions of teacher characteristics, information about student responses and learning environments, and final evaluation year results. Indicates that the evaluation program is characterized by considerable research on…

A laboratory experiment is described which presents some molecular parameters of iodine molecule by studying iodine spectrum. Points out this experiment can be conducted by sixth form students in high school laboratories. (PS)

A short description of the Physics Computer Development Project at the University of California, Irvine, concerned with effective ways of using computers in the teaching environment. (Author)
