Reviews very generally the desirability of college science departments redirecting some of their efforts towards interdisciplinary goals, and proposes second-level courses given through the combined efforts of several science departments. (PR)

Describes a study, involving high school earth science teachers, to determine if the level of the teacher's questions influenced student achievement.

Speed and simplicity allow the refractometer to be used at many levels of instruction. The optical theory for its operation is reviewed, as are the various uses of the refractometer, including its usefulness in introducing and demonstrating optical theory and in determining optical properties of minerals. (PR)

Discusses the development of a new concept about the nature and origin of earthquakes. The concept is based on the observation that the average dip of deep earthquake foci is 60 degrees. The location of the so-called "Rouse belts" of intense seismic activity is suggested as a student activity. Bibliography. (LC)
