The history of the National Aeronautics and Space Administration Skylab program is provided in this three-part book. Part I (chapters 1 to 5) traces the origins of the Skylab concept from its emergence in the period 1962-65 through its evolution into final form in 1969. Part II (chapters 6 to 13) focuses on the period from 1969-73, considering the…

Nine lessons which involve the use of marine organisms in the classroom are presented in this seventh-grade biology unit. The unit offers instructors alternative ways of meeting common life science goals. It is not meant to be an extra curriculum added to the normal course load, but was developed to consolidate a group of activities designed for…

Aims of classroom-centered research on second language learning and teaching are considered and contrasted with the experimental approach. Attention is briefly directed to methodological problems of experiments, such as controlling classroom events in various ways, and to conceptual weaknesses with study variables. In contrast, classroom-centered…

Legal, ethical, and procedural guidelines for the participation of mentally retarded people in research were solicited from 167 agencies, of which 67 responded. A variety of documents was cited by the respondents. The documents appeared to establish the outside limits of ethical practice but did not establish actual procedure. Furthermore, the…

This 2-3 week high school chemistry unit is designed to provide students with an awareness of Gasohol as an energy alternative. Gasohol is a blend of 10 percent pure ethanol and 90 percent unleaded gasoline. The unit consists of nine activities (five laboratory experiments, three informational readings, and a sample problem activity). The five…

Investigations in Natural Science is a program in secondary school biology, chemistry, and physics based upon the description of science as a quest for knowledge, not the knowledge itself. This teaching guide is designed for use with the 19 chemistry investigations found in the student manual. These investigations focus on concepts related to:…

Investigations in Natural Science is a program in secondary school biology, chemistry, and physics based upon the description of science as a quest for knowledge, not the knowledge itself. This teaching guide is designed for use with the 36 physics investigations found in the student manual. These investigations focus on concepts related to:…

Various research studies designed to enhance knowledge about the earth's core are discussed. Areas addressed include: (1) the discovery of the earth's core; (2) experimental approaches used in studying the earth's core (including shock-wave experiments and experiments at high static pressures), the search for the core's light elements, the…

The Rockwell AIM 65 is recommended for use in physics laboratories. Among advantages cited are that the basic board can be purchased customized; for example, it can be purchased with or without a printer, power supply, extra memory, and other items. In addition, the computer is basically designed to control equipment and take data from peripheral…

Background information, lists of materials needed, and procedures are provided for 12 electrochemistry experiments. The experiments involve investigating: (1) a simple electrical circuit; (2) how a doorbell works; (3) how a two-way switch works; (4) conductors and insulators; (5) controlling current with a pencil; (6) what an electrolyte is; (7)…

Francis Bacon began defining scientific methodology in the early 17th century, and secondary school science classes began to implement science labs in the mid-19th century. By the early 20th century, leading educators were suggesting that science labs be used to develop scientific thinking habits in young students, and at the beginning of the 21st…

Infant reaction to adult speech was studied through frame-by-frame analysis of sound films. Infants' actions were found to be synchronized with the organized speech behavior of the adults in his environment. (ST)
