Part two of a two-part article gives details of the threat of off-road vehicles to the terrain and wildlife of desert areas and to cultural values. (JR)

Reports the results of a study designed to analyze and classify the items used in ACS-NSTA High School Chemistry Tests according to the six cognitive levels of Bloom's Taxonomy. Over one-half of the test items were found to be in the cognitive levels of Comprehension, Application, and Analysis. (JR)

Examines the legal and constitutional implications of the fundamentalist movement to win equal time for creation doctrine in science and biology textbooks. (JR)

Reports data on 135 students completing the first year of the Nebraska Physical Science Project (NPSP). Those students who were most successful in this integrated and individualized course perceived themselve(PB)

Describes the way in which quantum ideas are incorporated into the Nuffield advanced physics course. Quantum theory is presented as an enormous intellectual leap to be excited by, puzzled over and thought about, not as a set of results and equations to be packed away in the mind. (Author/MLH)

Describes a simple tensiometer which provides good approximations to Young's Modulus and acceptable tensile test curves. (Author/GS)

Describes a method for offering additional topics in high school chemistry at minimal cost and at times convenient to the student. The method utilizes an independent study approach, using a slide sorter and cassette player. (GS)

Describes a method of time-of-flight determination utilizing a sound-actuated switch, an electronic flash, and a loaded camera. (GS)

Describes a calibration technique for a small motor which, when driven as a generator, can be used for a speedometer. The generator output can be fed to an oscilloscope to provide a sweep in which the vertical axis is velocity and the horizontal axis, time. (GS)

Summarizes a report issued by a National Science Foundation (NSF) review team concerning pre-college science curriculum projects and recommends a redefinition of NSF's role in implementing natural and social science curricula in the future. Suggests a more systematic approach to the monitoring of curricula projects and awarding of funds. (BR)

Explains a method of exploiting recent interest in automobile safety to demonstrate, qualitatively, concepts of momentum and energy. (GS)

Reports a study of 61 secondary school students in which a theoretical explanation of structure in communication was used to create science communications of different levels of structure and to determine the effects of these treatments on knowledge acquisition. (GS)
