Describes various parts of a mini car and their chemical composition. Useful information is included for science teachers to relate basic chemistry concepts and techniques with their application in automobile industry. (PS)

Describes books and other materials a teacher can select from in developing a unit on Chicano literature. (MM)

Includes thirteen topics relating to laboratory activities, organisms, and teaching materials for secondary school biology classes. Also provides a reading list of articles published during 1972 that are suitable for A and S level biology. (JR)

Describes a simple manual simulation exercise used in a college sophomore course in environmental biology. Demonstrates ways in which biotic potential and other physiological and behavioral characteristics of living organisms may interact with environmental factors to produce the kind of population behavior actually observed in the real world. (JR)

Describes a program in environmental education in which secondary school students and teachers extensively studied the North-eastern region of the United States on a one month camping trip. Details of the budget, suggested personal equipment, and group camping equipment are provided. (JR)

Discusses an experience of conducting educational programs which proceed at students' own pace and in their own time. Concludes that people of wide differences in ages and backgrounds can be given opportunities to continue their lifelong independent learning through the new approach. (CC)

Questions the feasibility of, and validity of the concepts behind, some of the new procedures proposed by the Water Resources Council. Concludes that the proposed procedures, if accepted in their present form, will bias water resource management in favor of development and against the preservation of the natural environment. (JR)

Describes the measurement of electric potentials by means of a flame probe. This method is used extensively in the new Nuffield Advanced Level Physics course, and provides a means of taking reliable quantitative results in an area of most school courses where the majority of the work is qualitative. (JR)

Examines the fallacies inherent in the concept of human population density, and demonstrates how viewing population density within both a demographic and cultural context can throw into question some of the standard current conceptions concerning the meaning of man-land ratios. (JR)

Summarizes the historical development of physical knowledge which is characterized by increasing generality and depth. Concludes that the intention to use a unique deductive logical system to describe satisfactorily all physical phenomena is still an unsolved problem for the physics community at present. (CC)

The development of career education is discussed, and five projects are reported. Specifics for the role of social studies' teachers are given: ideas and data sources for introducing and orienting students to the world of work; learning resources, general, and professional resources. (KM)

The status of science and scientists has changed. Sources of support such as the government, industry, and private foundations have been reduced. (DF)
