Short reports contributed on a variety of biology topics are presented. (CP)

Short reports contributed on a variety of topics in chemistry are presented. (CP)

A variety of topics in physics are covered by these contributed teaching and laboratory equipment suggestions. (CP)

Reviews experiments performed in a mobile spectroscopy laboratory. (SL)

Associates science teacher "bad days" with the inability to answer the questions asked by students. Proposes that publications focus on providing the answers to recurring questions experienced by science teachers. (CP)

Three studies are described in which choice reaction time (RT) was related to such psychometric ability measures as verbal comprehension, numerical reasoning, hidden figures, and progressive matrices tests. Fairly consistent negative correlations were found between these tests and choice RT when high school samples were used. (Author/CTM)

Describes benefits and techniques for utilizing Mormoniella vitripennis (jewel wasps) in teaching biology. Feeding, courtship, egg-laying, and insect behavior investigations are presented. (SL)

Provides a variety of science activities structured around the germination and growth of oak trees from acorns. (CP)

Reports on apparatus for generating Lissajous figures, projecting Poisson's spots, photographing diffraction patterns, electric heating, and projecting moving longitudinal waves on an oscilloscope. (SL)

Describes the use of an interactive computer terminal for introductory laboratory experiments. (SL)

Efforts to establish a library for laboratory instructional materials is being initiated by a group of concerned university educators. The main function of this library will be to collect descriptions of biological systems and supporting materials that are effective in laboratory instruction. Contributors are being solicited. (Author/MA)

Describes the operation of the computer program and a sample print-out is provided. (CP)

Reports an experimental procedure for a course in physical organic chemistry to illustrate correlation between structure and reactivity. (SL)
