Describes how bottle collecting can be used for serious studies. The emphasis in the activity is on systematic exploration for bottles and identifying the period when the bottles were used. Bottles, one hundred or more years old, can be found in many junk yards. (PS)

Lists materials and procedures for constructing a model that demonstrates certain aspects of the Coriolis effect. Materials include an electric drill motor, voltage control, toy dart gun and darts, wood blocks of varying dimensions. Includes description of an experiment illustrating relationship between speed of rotation and amount of apparent…

Data are presented from a study made, 1972-73, using a direct-mail questionnaire. Seventy-nine percent return was indicated. Found that most teachers needed background improvement, that facilities and materials were not considered adequate and that enrollment has increased greatly from 1961 to 1972. (EB)

Reports the results of a study conducted in Virginia to gather information concerning the background of earth science teachers, opinions of these teachers regarding earth science education, and information regarding curriculum and materials for earth science education. (JR)

Uses a vortex device as a model to study low-pressure systems and other related investigations. (LS)

This study investigated two broad questions: (1) What are the trends evident in status studies of earth science education across the nation and in Virginia between 1964 and 1972 and how do the trends in the nation and in Virginia compare; and (2) With recommendations for pre-service education, in-service education, and certification requirements…

Describes the construction and use of a model for calculating the hours between sunrise and sunset for earth science students. (SL)

Describes a variety of water erosion situations which can be shown with the use of a streamtable. Individual and group experiments are suggested and photographs of some situations which may be created are provided. (CP)

Describes the communication system being developed by the Virginia State Science Service to obtain more systematic input from the local school systems and to give better information feedback from the state level. (Author/MA)

Emphasized is the need for statewide direction in secondary science education coordinated by personnel from local school districts, local universities, and state departments of education. A state communication network is described and its impact on earth science, preservice and inservice college offerings, research, and other areas discussed. (DC)
