Proposes a method to estimate the number of civilizations which may exist in the universe. Reviews attempts which have been made to contact these bodies. (CP)

Describes how to collect micrometeorites and suggests a number of related activities such as determining the number of meteors entering the atmosphere and determining the composition of the micrometeorites. (BR)

Points out the need for a greater awareness, among physicists, of medieval physical science. Reviews briefly and gives examples of notable achievements of the era and argues that the view of science of fourteenth-century nominalism has greater affinity to today's theoretical physics than that of the Scientific Revolution. (Author/GS)

Discusses instrumentation and describes such research areas as the albedos of the brighter planets, rotation rates and atmospheres of the larger and brighter satellites, brightness changes of outer planets, asteroid rotation rates, and variable stars. (GS)

Describes the construction of a model to show circumpolar stars. (BR)

THE EFFECT OF PLANNED DIFFERENCES IN TEXTUAL MATERIALS ON ELEMENTARY STUDENTS' SCIENCE ACHIEVEMENT AND ATTITUDES WAS INVESTIGATED. A CHAPTER FROM A RECENT SCIENCE TEXT WAS REWRITTEN IN SIX DIFFERENT FORMS WHICH EMPHASIZED OR DEEMPHASIZED QUESTIONS, ACTIVITIES, OR INCONGRUITIES INCLUDED IN THE ORIGINAL FORM. THE MATERIALS WERE RANDOMLY ASSIGNED TO…

THE STATUS OF EARTH AND SPACE SCIENCE COURSES IN PENNSYLVANIA WAS INVESTIGATED. OF 461 QUESTIONNAIRES SENT TO SECONDARY SCHOOLS OFFERING EARTH AND SPACE SCIENCE, 172 WERE RETURNED. TABLES AND PERCENTAGES WERE USED TO INTERPRET FINDINGS. MORE THAN 87 PERCENT OF THE RESPONDENTS HAD BEEN TEACHING EARTH AND SPACE SCIENCE FOR LESS THAN FIVE YEARS -…

ARTICLES ON EARTH AND SPACE SCIENCE ORIGINALLY PUBLISHED IN "THE SCIENCE TEACHER" DURING 1960-1966 ARE INCLUDED IN THIS MANUAL FOR SECONDARY TEACHERS. THOSE DEALING WITH THE FORMATION AND STRUCTURE OF THE EARTH, CLIMATE, WEATHER, AND THE OCEANS PROVIDE TEACHER BACKGROUND INFORMATION. ANOTHER SERIES OF ARTICLES INCLUDES INFORMATION ABOUT…
