Integrates science and social studies in several activities that study weathering caused by the freezing and thawing of rocks, wind erosion, and the effects of weathering on tombstones. Cites the possibility of these activities leading to an interdisciplinary exploration of pollution, customs, and populations. (MCO)

Presents a sequence of activities designed to allow eighth grade students to deal with one of the fundamental relationships that govern energy distribution. Activities guide students to measure light bulb brightness, discover the inverse square law, compare light bulb light to candle light, and measure sun brightness. (two references) (MCO)

Describes techniques to avoid the time crunch and safety hazards associated with fitting labs into 45-minute periods. The author presents information on organizing people and things, adapting labs, and cleanup management. The author cautions against rushing a science lab to the point of compromising safety or student understanding. (PR)

Discusses modifications of the usual lecture approach for a environmental geology course by including class discussion, class projects, and group projects which are designed to help students see the relevance of geology to their lives. Author claims that in this interactive approach both instructor and students become more actively involved in the…

A program for teaching the concepts of electric energy, voltage, and current is proposed. The ideas and concepts are introduced in a sequence that places more emphasis on some aspects that are normally treated very briefly. A phenomenological orientation, qualitative and quantitative micro- and macroscopic treatments, and the inclusion of the…

The development and responsibilities of the Office of Technology Assessment (OTA) are discussed. Ways in which teachers can use the OTA, especially as a starting point for issues-oriented design work are suggested. Examples of publications from OTA are described. (KR)

The value and difficulties of long-term ecological monitoring studies undertaken in schools and colleges are reviewed. Rookeries, stream ecology, sand dune succession, fish population, and seed production and survival are presented as examples of successful studies. This is followed by a discussion of points to consider when setting up a long-term…

Presents the idea that, to improve secondary science, school science teaching students must be taught to use the activities of science: questioning, information gathering, hypothesizing, testing and conveying, and confronting current issues and problems in science. Activities and ideas that can be used to help students understand and use the…

The directions and diagrams for making a reflecting telescope and a refracting telescope are presented. These telescopes can be made by students out of plumbing parts and easily obtainable, inexpensive, optical components. (KR)

Described is the Vale Interactive Science and Technology Adventure (VISTA) center that caters specifically to primary school students, involves concepts and skills from the National Curriculum, and researches playing children's patterns of learning. The plans for the future and early descriptions of students reactions are reported. (KR)

The effect of sunlight on skin is described. Topics of discussion include the ozone layer, photosynthesis of vitamin D, tanning, the immune system, skin cancers, moles, prevention, sunscreens, effect of diet, vitamins C and E, the retinoids, carotenoids, and vaccines. Activities are provided. (KR)

A series of recipes that can be used to show how algae is used in diets around the world are presented. Information on the harvesting and preparation of the seaweeds prior to packaging and distribution is provided. The recipes use both red and brown seaweeds. (KR)

A method of teaching ecology that incorporates field trips and student projects is described. A list of possible field trips and directions for guiding students as they proceed with their projects are provided. (KR)

A rationale is presented for the use of inquiry activities in the biology classroom when teaching the concept of evolution. An annotated list of evolution laboratory activities from 18 nontextbook sources is included. Each annotation includes the title, source, major evolutionary concepts, and a brief description. (KR)
