Presented are 29 science activities for secondary school science instruction. Topic areas include botany, genetics, biochemistry, anatomy, entomology, molecular structure, spreadsheets, chemistry, mechanics, astronomy, relativity, aeronautics, instrumentation, electrostatics, quantum mechanics, and laboratory interfacing. (CW)

Eight activities for use in the science classroom are presented. Included are insect collecting, laboratory procedures and safety, recycling, current events, variable manipulation, scientific method, electricity, and mechanics (Newton's Second Law of Motion). (KR)

Described is a means of logging data from remote sensors in data files and then transferring the data to a spreadsheet for processing. The presentation of the data in tabular or graphical form is discussed. An example using temperature data from a model house is provided. (Author/CW)

Described is an activity which can be used to investigate heat expansion in a solid. Included are background, materials, procedures, and suggested discussion questions. A diagram of the apparatus is provided. (CW)

Two classroom activities designed to help students learn to distinguish science from superstition are presented. Procedures are discussed and the two activities are compared. (CW)

The use of concept maps, Vee diagrams, flow charts, and productive questions to increase student understanding of laboratory exercises and to improve student attitudes toward lab classes is discussed. Examples of each are provided. Student responses to these teaching methods are described. (CW)

Demonstrates how to promote the transference of concepts and principles developed in other curricula to enhance a student's subject matter mastery in soil classification. Describes course format, critical thinking techniques, and a course evaluation. A conclusion and references are included. (Author/RT)

Explores the structural behavior of polyenic pi systems such as isomerization and conjugation. Uses the simultaneous spectrophotometric analysis of a beta-carotene and lycopene mixture. Presents an empirical method to determine the number of double bonds in the polyenic carotenoid. (MVL)

Discusses electron spin resonance, a form of magnetic resonance spectroscopy, used to study electronic structure of molecules with unpaired electrons. Studies benzosemiquinone radical anions which are long-lived and inexpensive. Uses a Project SERAPHIM computer program to perform a Huckel molecular orbital calculation. (MVL)

Outlines some strategies used by science teacher educators to train teachers to make laboratory lessons a place for meaningful and useful learning, including content analysis of laboratory manuals, scientific inquiry, flexible organization, concept mapping, Vee heuristics, and inquiry oriented laboratory tests. (YP)

Presents the results of a chemistry program held at Purdue University from July 31-August 4, 1988. Topics reported include: chemistry's past, present, and future; new directions in chemical education, demonstrations and laboratories; and instructional strategies. Lists the 391 papers given at the conference and the 22 workshops. (MVL)

Discusses the nature of a nuclear magnetic resonance (NMR) experiment, the techniques used, the types of structural and dynamic information obtained, and how one can view and refine structures using computer graphics techniques in combination with NMR data. Provides several spectra and a computer graphics image from B-form DNA. (MVL)

Lists five module objectives and discusses the overall need for the modules. Indicates each module is preceded by a statement of the problem and objectives are aimed specifically at the anticipation and reduction of potential hazards. Offers examples of modules on fume hoods and on disposal of waste. (MVL)

Explains a science project conducted by the Boston Museum of Science to provide enrichment activities through an interaction between children and scientists. Provides information on the packets of creative problem-solving experiences, a description of the program, the culminating event, and joining procedures. (RT)

Describes a program for students or science teachers to integrate demonstrations into the science curriculum. Uses the idea of a chemical genie with numerous demonstrations to illustrate that science can be fun, to learn some indicators of a chemical reaction, and to discover factors that affect reaction rates.
