Reports an investigation of the effect of gender on ability to recognize simple definitions of concept words in science, as indicated by differences in test scores and in students' free writing "definitions" of physical science concept words. Significant gender differences favoring boys were found for students (n=1,635) of six Tasmanian…

Compares critical thinking ability of pupils in scientific situations and in real-life situations by administering multiple choice tests to Israeli ninth graders (N=344). Results confirm that students do not react similarly when confronted with equivalent situations presented in different contexts. (CS)

Presents results of a questionnaire sent to Australian school teachers concerning laboratory space allotments and class size. Summarizes data and compares results with the United States National Science Teachers Association recommendations on class size and space requirements. (CS)

Presents advantages and disadvantages of establishing a cooperative educational program for high-ability chemistry students in which governmental laboratory facilities are used by high school students. (CS)

Describes an inexpensive apparatus for the detection of gravity waves traveling through the ionosphere. The detector consists of a modified transistor radio with a ferrite-core antenna. Numerous diagrams accompany a lengthy description. (CS)

Presents some creative ideas that a high school chemistry teacher uses to stimulate right-brained activities in a chemistry classroom. (CS)

A two-part project involving critical thinking and writing skills focuses on a small crustacean and the scientific method. (Editor)

Indicates that at least 50 percent carbon monoxide is produced during the dehydration of sugar by sulfuric acid to a hot, black, expanded solid. Consequently, students should not be allowed to smell this product. Also lists six other findings related to this reaction. (Author/JN)

Describes procedures for monitoring students' responses in heart rate to various stimuli by the use of an electronic monitoring device strapped to the wrist. (CS)
