This is one of a series of units for environmental education developed by the Highline Public Schools. The unit on air pollution is designed for secondary school students in grades 7 through 12. There are five lessons in the unit; since some of the activities can take as long as 90 days, use of the materials needs to be carefully planned. Each…

This unit is a part of a series of materials produced by a project to develop locally applicable class, lab, and field materials in ecology and social studies for Guam junior and senior high school. While the materials were designed for Guam, they can be adapted to other localities. This unit is designed to interest the student in growing plants…

Secondary school students in a classification study spent more time in classifying plants in a seminatural environment than in classifying man-made geometrical objects in a classroom. No differences were found in these results with respect to race, sex, or age. (MLH)

Presents data from the external examination entries of the G.C.E. and C.S.E. to challenge statements that there is a swing away from science in the schools and that combined and integrated science are making great inroads into the teaching of chemistry and physics. (GS)

Suggests that students discover and evaluate their own values by studying a unit based on ethical issues in human experimentation. (LS)

Reports research findings that student achievement can be enhanced if teachers use more questions related to application, analysis, synthesis, evaluation, convergent production, and divergent production. (LS)

Gives the outline of a mini-course which utilizes science fiction to motivate science students. (LS)

Describes the procedure for dissecting a bulky stick insect. Also describes the maintenance of the live insects and how to obtain them. (MLH)

Describes the benefits and adverse effects of insects and concludes that the benefits outweigh the adverse effects. (LS)

Identifies seven methods for controlling insect pests and discusses the necessary training and responsibilities of pest managers. (PEB)

Draws together excerpts from Whitehead's writings on the nature of science, the nature of education, and the social science curriculum. Illustrates the use of Whitehead's work to answer the attacks of modern critics on science. (CP)

Brief suggestions are given on the following topics of interest to chemistry teachers: rate of reaction anaologies, a buffer effect demonstration on the overhead projector, and a year-end activity in general chemistry based on the student's laboratory skills. (BB)

Traces the formation of the concepts of acids and bases by describing theories ascribed to various scientists. (CP)

Describes the necessary procedures and equipment needed to modify the American Association of Physics Teachers' (AAPT) pocket calculator timer so that it can be controlled photoelectrically. (SL)
