Presents the following chemistry lecture demonstrations and experiments: (1) a versatile kinetic demonstration; (2) the Bakelite Demonstration; (3) applying Beer's law; and (4) entropy calculations. (HM)

Presents a formulations laboratory project in which secondary school students attempt to prepare a common household product from laboratory chemicals. (HM)

Video cassette demonstrations are useful in teaching experimental techniques and instrumentation. This article describes how the recorded demonstrations save instructor and student time, how they can be integrated into a multimedia teaching format, and how recordings support student independence. (Author/BB)

Presents sixteen project notes developed by pupils of Chipping Norton School and Bristol Grammar School, in the United Kingdom. These Projects include eight biology A-level projects and eight Chemistry A-level projects. (HM)

Describes activities that demonstrate the effects of factors such as wind velocity, water temperature, convection currents, intensity of light, rate of photosynthesis, atmospheric pressure, humidity, numbers of decomposers, presence of oxidizable ions, and respiration by plants and animals on the dissolved oxygen concentration in water. (MA)

Reports a study of 99 twelfth graders to determine the nature and extent of misconceptions in chemical equilibirum and its relationship to achievement on tasks involving concrete and formal thought. Results indicate assessment of the student's cognitive level of development should be attempted prior to introducing formal level chemical…

Describes an introductory chemistry course presented at the University of Illinois, Urbana-Champaign, in which students meet four times a week in classes of 25 each with a teaching assistant to view lectures via videocassette. (SL)

Describes the College Entrance Examination Board (CEEB) Advanced Placement Program (AP) which allows secondary level students to pursue college-level studies in high school. (SL)

Describes an electroplating experiment which utilizes photovoltaic (solar) cells to drive the chemical reaction. (SL)

Reports on a screen projectable model of atomic orbitals useful in developing a student's understanding of molecular structure. (SL)

Provides a general history of the Doctor of Arts Program with particular emphasis on chemistry education. (CP)

Reviews the use of hand held calculators as an alternative to computer assisted instruction at the secondary level in chemistry classes. (SL)

Three demonstrations are described: paramagnetic properties of Fe(11) and Fe(111), the preparation of polyurethane foam: a lecture demonstration and the electrolysis of water-fuel cell reactions. A small discussion of the concepts demonstrated is included in each demonstration's description. (MR)

An experiment in rapid scanning polargraphy using the Health Polargraph System is described. The experiment was designed to be used in an undergraduate course on instrument analysis. The theory, instruments, and results of the experiment are also discussed. (MR)

Describes science-related competitive events in which 10th and 11th grade students participated. The organization and operation of the olympiad is detailed. (CP)
