This document presents a sample of the Arkansas science curriculum and identifies the content standards for physical science systems, life science systems, and Earth science/space science systems for eighth grade students. Each content standard is explained and includes student learning expectations, eighth grade benchmarks, assessments, and…

This paper summarizes two companion studies that were designed to investigate the impacts of an inquiry teaching method on Earth science students' achievement and attitudes towards Earth science in secondary schools. Subjects were 557 students (9th grade) enrolled in 14 Earth science classes. Two Earth science units, including topics of astronomy…

This CD-ROM contains four astronomy and space science learning center sites individually captured from the World Wide Web in January of 1999. Each site contains its own learning adventure full of facts, fun, music, beautiful images, movies, and excitement. Space science learning sites include: (1) Imagine the Universe! geared for ages 14 and up…

This packet contains a unit on teaching about volcanoes. The following question is addressed: How do volcanoes affect human life? The unit covers approximately three weeks of instruction and strives to present volcanoes in an holistic form. The five subject areas of art, language arts, mathematics, science, and social studies are integrated into…

Reviews development of NSF (National Science Foundation) earth science summer, inservice, and academic year institutes. Includes statistics from 1957 to 1971 for number of participants, topic areas, number of institutes, number in each state, and other related information. Institutes are an important source of advanced degrees for secondary…

Discusses ATP synthesis in mitochondria/chloroplasts and cause of an antipodal high tide. Also discusses a simple field experiment on regulation of osmotic potential by Salicornia (pioneer plant of estuarine sale marshes) and use of a key to identify British mosquito larvae. The latter includes procedures for collecting, recognizing, and finding…

Sedimentary patterns and hydraulic effects can be studies in model streams which are not to scale. The "Western River" is such a model which is being used effectively at Western Carolina College. Construction of the model, student exercises, and observations made when using the model are discussed. (Author/JN)

To test the literal biblical account of Noah's flood, four sources of possible flood waters were evaluated to determine if a natural (as opposed to supernatural) explanation is possible. Sources include rain, hydrothermal springs, and two types of cometary impact. Thermodynamic constraints preclude a natural means of accounting for the flood.…

Reports using a closed-circuit television system for presenting the concept of homogeneous strain so the complete straining sequence can be followed from the initial state through progressively increasing strain ratios. Suggests photographing the screen for materials for student exercises. (DS)

Reported is a method of producing artificial lightning in an ordinary clear lightbulb. The appearance of sparks produced is that of a miniature stroke of forked lightning seen in natural thunderstorms. The sparks also show the intricate branching patterns often seen in natural lightning. (JT)

Describes a self-paced undergraduate environmental science course focusing on a theme that earth is similar to a spaceship inasmuch as: (1) both possess finite room and resources, and (2) living things are dependent upon life-support systems for continued survival. Includes a list of laboratory and learning activities. (DS)

Described is a computer program which accepts face data, performs all necessary symmetry operations, and produces a drawing of the resulting crystal. The program shortens computing time to make it suitable for online teaching use or for use in small computers. (Author/DC)

Describes a teaching method which forces students to gather data and draw influences in order to synthesize a description of the geological events responsible for current topography. (Author/MA)

Presents activities to be used by a class of fifth graders on a field trip to a stream. Photographs illustrate the techniques and the setting described. (HM)

Discusses changes in the methods of earth science fieldwork brought about by the introduction of the National Curriculum to UK schools. Teachers have traditionally described and interpreted geology for pupils. Teachers now need accessible, safe sites close to schools. The sites must allow pupils to identify problems for themselves and solve them…
