This paper is an examination of a teacher professional development program in northeast Louisiana, that provided 30 teachers and their students with the technology, skills, and content knowledge to collect data and explore weather trends. Data were collected from both continuous monitoring weather stations and simple school-based weather stations…

Provides a survey and a review of earthquake activity and global tectonics from the advancement of the theory of continental drift to the present. Topics include: an identification of the major seismic regions of the earth, seismic measurement techniques, seismic design criteria for buildings, and the prediction of earthquakes. (BT)

Focuses on recent research on currents and eddies of the earth's oceans. Special emphasis is given to instrumentation involved in studying the oceans. (SA)

Presents an activity that is part of a unit on topography and land masses in the earth science curriculum. Involves students learning about scientific inquiry, comparing a model with what it represents, making and interpreting scale drawings, learning how to use new instruments, and learning about computation and estimation. (JRH)

Discussed are two techniques that can be used to directly test the theory that the plates which make up the crust of the earth are still moving. Described are the use of satellite laser ranging and very long baseline interferometry. Samples of data and their analysis are provided. (CW)

Described are efforts to organize the research efforts concerning global change. Objectives include the development of long-term monitoring programs, global process research campaigns, and predictive computer models. (CW)

Results from the analysis of land and marine records from the past century are presented. It is indicated that the planet earth has warmed about one-half of a degree celsius. The uncertainty of these measurements and future warming trends are discussed. (CW)

The Hubble Space Telescope project is described. Discussed are the project directors, construction, launch, deployment, hazards, rationale, and hope of the project. (CW)

Presented is the best understanding of the flaw discovered in the optics of the Hubble Space Telescope and the possible solutions to the problems. The spherical aberration in the telescope's mirror and its effect on the quality of the telescope's imaging ability is discussed. (CW)

The construction and use of an instrument to monitor ultraviolet radiation from the sun are discussed. A diagram of the ultraviolet-B radiometer which is connected to a digital voltmeter is provided. (CW)

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.
