Instructions are given for constructing two models, one to illustrate the general principles of symmetry in T=1, T=3, and T=4 viruses, and the other to illustrate the disposition of protein subunits in the T=3 plant viruses and the picornaviruses. (Author/CW)

Described is a workstation equipped with a personal computer and a research-quality data-acquisition interface for instrumental data acquisition and analysis for chemistry and physics courses. Hardware, software, and functions of the apparatus are discussed. (CW)

Described is the development of a course for future science teachers through the collaboration of middle school teachers, mathematicians, scientists, and science educators. The experience of the team approach and a field test of the resulting activities are discussed. (CW)

Described is a survey of two-year chemical technology programs in the United States. The results of the survey are presented, and a set of recommendations for the improvement of chemical technology programs is presented. (CW)

Presented is an activity designed to raise energy awareness, teach electricity conservation, and show students how to carry out a science project. Included are objectives, a list of materials, procedures, student information sheets on meter reading, sample charts and graphs, and a sample awards certificate. (CW)

Described is a one-semester interdisciplinary course for upper division undergraduate students. Discussed are keynote speakers, course content, reading materials, evaluation of students, and course modifications. An advertisement for the course and a copy of the course outline are included. (CW)

Described is a skit to be performed in an elementary school classroom about the water cycle. Included are a list of materials, procedures, and suggestions for role cards for the players. (CW)

Provides instructions and diagrams for making a life-sized morpho butterfly to wear on the finger and a paper bromeliad. Includes a pattern for copying. (RT)

Uses a discrepant event to teach students about volume and area. Outlines directions for class demonstration, needed materials, questions, a story problem, and related activities to perform this assignment. (Author/RT)

Describes a program in which second-year biology students use plasmid isolation to remove DNA from Escherichia coli bacteria and subsequently ligate and transform it into other E. coli bacteria. Cites ways teachers can get involved in current research that allows student participation. (RT)

Describes an activity in which students graph changes in tides and ocean levels over a period in order to obtain a visual representation of the changes taking place and their effects upon the Earth. Provides questions for students to answer after construction of the graphs. (RT)

Discusses the presentations of chemical demonstrations, hands-on experiments, and magic shows. Presents 12 guidelines to follow when presenting chemical demonstrations. Points out the obligations of the presenters for the safety concerns of the general public. Notes information available from the American Chemical Society. (MVL)

Describes a method for making a simple, inexpensive apparatus which can be used to determine Planck's constant. Provides illustrations of a circuit diagram using one or more light-emitting diodes and a BASIC computer program for simplifying calculations. (RT)

Presented are two chemistry demonstrations: (1) an alternative method for the demonstration of the properties of alkali metals, water is added to small amounts of metal; (2) an exploration of the properties of hydrogen, helium, propane, and carbon dioxide using an open trough and candle. (MVL)

Described is an activity for grades kindergarten through three called "Let's Slide Down the Slope." Shows how to apply mathematics and scientific skills to the sliding demonstration. Provided are the procedures, a list of materials, key concepts, background, and extension of the activity. (YP)
