Describes experiments, demonstrations, activities and ideas relating to various fields of chemistry to be used in chemistry courses of secondary schools. Three experiments concerning differential thermal analysis are among these notes presented. (HM)

Describes an instructional unit on heating and lighting in the home. Discusses the location, production, distribution and use of fossil fuels as well as the production and distribution of electricity. (GA)

Explains some of the ways in which dried yeast has been used in sixth-form work to illustrate some points and principles relevant to a high school biology course. (Author/GA)

Provides a reading list of articles and journals for high school biology on a wide range of topics. A few short articles and experiments on biology related topics are also given. (GA)

Discusses attitudes of secondary school students towards science as a career choice and their perception of science as a professional activity. Concludes that many students hold unfavorable attitudes towards science and scientists. This may contribute to the poor social status of professional scientists in contemporary British society. (GA)

Describes how a thermosyphoning solar water heater capable of heating 110 kilogram of water to 80 degree Celsius and maintaining this temperature for 24 hours was constructed by four students in the fifth form of Sekolah Date Abdul Razak, Seremban, Malaysia in 1976. (HM)

Provides examples from advanced secondary school science which are amenable to the use of a programmable calculator. Compares the use of the calculator to a computer terminal. (CP)

Two analytical methods were used to measure the comparability of a CSE physics examination which contained a practical test and a theory paper. The two measures appeared to be evaluating essentially the same property. (CP)

Includes procedures for demonstrating anaerobic respiration in peas, isolating virgin Drosophila females, solving mortality problems in young gerbils, measuring dissolved oxygen, constructing models for transpiration and DNA molecules, freezing chick embryos, mixing nutrient media, illustrating Darwinian ecological principles, and detecting…

Reported are methods employed for measuring consistency in teacher assessment of practical notebooks in A-level biology. Use of criterion referenced scales is discussed. (CS)

Contains contributed suggestions for laboratory equipment, chemistry activities, and explanations of chemical reactions. (CP)

Provides the syllabus for a course which examines the role of creative thinking with the scientific method and the interrelationship of science and society. (CP)

Discussed are causes of fires that occur in school science laboratories and ways of preventing them. (RH)

Describes a chemistry "trail" (similar to a nature trail) which focuses on chemical phenomena in the environment. The trail includes 20 stops in and around a local school. Types of phenomena examined include building materials, air pollution, corrosion of metals, swimming pools, and others. Additional activities are also suggested. (DH)

Provides background information for teachers on the mathematical and biological theories of death and aging, focusing primarily on higher animals and humans. Areas of the curriculum into which such topics could be introduced are outlined. (JN)
