Describes a science fiction writing project for ninth-grade physical science classes. Provides some examples of science fiction stories written by the students. Selects grammar, punctuation, science content, sentence structure, and originality as the criteria of grading. (YP)

Describes a science club at the high school level for promoting opportunities to apply the student's skills outside the classroom. Provides several tips for starting a club. (YP)

Describes 11 hands-on activities involving genetics; principles of chemical luminescence; a nucleus model; dissection pins; science, technology, and society (STS) courseware; plant dyes; the scientific method; current events; a portable planetarium; solar energy; and burning tests. (YP)

Reviews four computer software packages including: "The Physical Science Series: Sound" which demonstrates making waves, speed of sound, doppler effect, and human hearing; "Andromeda" depicting celestial motions in any direction; "Biology Quiz: Humans" covering chemistry, cells, viruses, and human biology; and "MacStronomy" covering information on…

Presents a checklist developed to help chemistry teachers assess conditions in the storeroom. The checklist format facilitates a systematic assessment of storage conditions and serves as a record of where improvements are needed. Also lists classes of chemicals requiring special storage precautions. (Author/SK)

Describes a simple activity using modeling clay to help biology students better understand the relationships between longitudinal, serial or cross-sections, and the entire structure from which the sections were made. (Author/SK)

Describes the linguistic approach for improving science vocabulary skills. Its efficiency lies in the fact that mastery of a relatively small number of prefixes, suffixes, and word roots unlocks a vast treasure of scientific terminology. (Author/SK)

Describes and evaluates the effectiveness of some optical media enabling visually impaired students to become active learners in the science classroom. (SK)

Describes paleontological studies of trace fossils (the impressions that record the animal's activity) such as dinosaur footprints. Discusses the importance of findings to our knowledge of dinosaur social behavior and community structure. Also tracts evolution of behavior from the Upper Triassic through the Upper Cretaceous, building evidence of…

Describes an apparatus (called the "Rainbow Cup") used for demonstrating the colored rings produced by constructive interference in soap films. Discusses construction of the Rainbow Cup and gives hints for its use in the classroom, especially in relation to classroom humidity. (JM)

Recommends using dramatic demonstrations on the energy in chemical systems as an audiovisual adjunct to lectures and laboratory sessions. Lists materials needed and provides procedures including safety tips for various experiments to produce chemical light, heat, and electricity; and concludes with hints for preparation/rehearsal. (JM)

Describes a minicourse on experimental hypotheses. The courses which treats the investigative nature of biology as a major theme, teaches nonrigorous problem-solving and engenders the excitement of self-discovery. Manipulation of variables in relation to controls, the principles of deduction and induction, and their application to selected…

Presents information on Halley's Comet including its discovery, impact on history, planned investigations related to its 1986 return, where and when to make observations, and predicted calendar of events. Gives general information on comets such as physical structure, theoretical origin, and paths and provides an annotated reference list. (JM)
