Discussed is a science-appreciation course based on goals and performance objectives such as having the student appreciate the concepts of science and the men who put these concepts into readable and understandable terms. (DF)

Describes experiments demonstrating that root pressure in plants is probably controlled by a circadian rhythm (biological clock). Root pressure phenomenon plays significant part in water transport in contradiction with prevalent belief. (PS)

Discusses the development of a course designed to interest the average high school student. It is socially oriented in its approach to science and has been employed, in both the United States and Israel, for nonscience students. (DF)

Discusses briefly some features of the Australian Science Education Project, ASEP, and experiences of teachers and students with these materials. Implications of this program are identified in terms of cost, time, classroom management, teacher education, and evaluation. (PS)

One of a series on different topics designed to guide college physicists to some of the literature and teaching aids that may help them improve course content. (DF)

Describes how bottle collecting can be used for serious studies. The emphasis in the activity is on systematic exploration for bottles and identifying the period when the bottles were used. Bottles, one hundred or more years old, can be found in many junk yards. (PS)

Describes individualized and motivational features of a high school chemistry program. The students are given the list of activities with the approximate time for completing them. Tests are given when a student is ready. Advantages and disadvantages of this program are listed. (PS)

Six beginning science teachers describe some of their most difficult problems in their first or second year of teaching. (AL)

Short notes on a variety of science topics provide information derived from space sciences that can be used to add interest and up-to-date data to science lessons. Topics are arranged alphabetically from Alpha particles to X-rays, and include some from each of the physical, earth, and biological sciences. (AL)

Consideration of the force of gravity in some simple accelerated systems. Ambiguity about the use of up'' and down'' arises in coordinate systems not at rest with respect to the surface of the earth. (DF)

Questionnaires were sent to 107 earth science teachers to determine pupil attitude, teacher attitude, teacher preparation, materials used, methods used, and a rationale for continued growth of earth science. (DF)

Discusses the basis of the theory of preformation used in teaching heredity and development. English translation of the original document written by Hartsoeker is included that reveals the theory was an imagined one without concrete evidence. (PS)
