Describes various demonstrations and experiments simulating groundwater flow and chemical reactions. (SL)

Presents an experiment for determining the pH of shampoo. (SL)

The right brain hemisphere is concerned with sensory learning, including creativity, intuitiveness, and metaphors. This article gives two science activities designed to stimulate the right brain function and to motivate elementary students. The two activities concern batteries and metamorphosis, and each includes the concept, story (fantasy),…

Describes an experiment to introduce students to qualitative and quantitative aspects of neutron activation analysis. (SL)

Describes an aviation field day project organized and promoted on the secondary level. (SL)

Describes using picture riddles to present situations, problems, or puzzles in graphic form to stimulate student enthusiasm. Included are five picture riddles. (SL)

Suggests ways to avoid some of the problems students have learning the principles of organometallic chemistry. Provides a description of an experiment used in a third-year college chemistry laboratory on molybdenum. (TW)

Reviews the use of spreadsheets and gives examples of how they can be adapted for data analysis in a science laboratory situation. Highlights the benefits and limitations of this approach for students. (ML)

Describes an exercise which provides a small data set consisting of the localities where various genera of a fictitious group of fossil "Archaeomorphs" have been found on various continental blocks. The activity can be used to develop hypotheses regarding plate tectonic processes and the present arrangement of fossil localities. (TW)

Promotes a reductionist approach to teaching about the endocrine system in high school biology and anatomy courses. Encourages the study of how hormones travel to the cells and affect them. Provides suggestions for activities and discussion questions, along with sample diagrams and flow charts. (TW)

Explains how databases can be used to enrich and complement the science curriculum. Provides examples of applications of databases to science activities and experiments. (ML)

Describes a physical chemistry experiment that uses Fourier transform (FTIR) spectrometers and microcomputers as a way of introducing students to the spectral storage and manipulation techniques associated with digitized data. It can be used to illustrate FTIR spectroscopy, simple kinetics, inorganic mechanisms, and Beer's Law. (TW)
