Discusses teaching of two project experiments to nonscience students who were asked to measure the acceleration of a system any way they could and investigate any phenomena that they thought might follow a Poisson distribution. Indicates that physics learning performed outside the physics building is the experiment highlight. (CC)

Describes a course at Michigan State University in which students carry out self-experiments in nutrition. Self-experiments help to impress students with importance of human nutrition and offer insights into problems associated with altered dietary patterns. A number of possible self-experiments in nutrition are listed. (JR)

Discusses the experience of a British exchange physics teacher with the physics instruction in the United States of America, including students' learning and extracurricular activities. Indicates that the state of physics in the United States is found to be less healthy than in Britain. (CC)

Discusses physical phenomena which can be demonstrated by using a coffee cup, involving the short-range field, alpha-particle scattering, standing waves, and Bohr's closed electron orbits. Indicates that observation of the physics of the classroom in everyday objects can attract student interest in physics learning. (CC)

Discusses the use of two television sets with UHF coverage and a window screen or aluminum foil reflector to conduct a take-home experiment in physics. (CC)

Summarizes the Darwin theory of x-ray diffraction in thin crystals or crystals with a mosaic texture and its modified application to crystals with three-dimensional electrostatic dipoles. Indicates that the dynamical theory is brought into its present relevance by the improvement of single crystal growth techniques. (CC)

Describes the basic features of the Keller plan or Personalized System of Instruction (PSI), and presents a review of evaluative research on this teaching method. The Keller plan is an individually paced, mastery-oriented teaching method that has had a significant impact on college-level science education in recent years. (JR)

Examines new directions in ecological research in which ecologists are analyzing systems with theoretical models and are using descriptive studies to confirm and extend their studies. The development of a model relating to species equilibriums on islands is now being applied to problems of conservation of wildlife in national parks. (JR)

Presents reasons for accepting alternative modes of education that might help students to escape perceptual traps and limitations to human potential and growth. (JR)

Describes the structure and content of a multidisciplinary environmental science course for non-science majors offered at Southern Illinois University. (JR)

Presents a review of genetic engineering, in which the genotypes of plants and animals (including human genotypes) may be manipulated for the benefit of the human species. Discusses associated problems and solutions and provides an extensive bibliography of literature relating to genetic engineering. (JR)
