Discusses how teachers turn an idea into a meaningful lesson. Suggests class brainstorming, using community resources, library searches, and further classroom activities. (YP)

Introduces some activities to help children develop their processing and inquiry skills with a substitute teacher as well as regular teachers. Illustrates 25 kinds of skills. (YP)

Uses a demonstration done by John Tyndall in 1856 to show that geological processes can produce striking changes, such as slate formation, by slow and incremental means. Explains how Tyndall's demonstration can be replicated in the classroom using paraffin or beeswax to produce the layering change similar to slate. (CW)

Describes a set of 10 activities which introduce mainstreamed junior high school students to concepts relating to fossils and dinosaurs. Provides students with opportunities for learning the concepts of change and adaptation, as well as fossil facts and terminology. (TW)

Announced is the availability of a set of lessons for middle school and secondary school teachers who want to teach about energy. Concrete experiences are emphasized in this instructional program. (SA)

Lists science/art activities which involve students in general observation and imaginative visualization. (CS)

Discusses methodology for several activities which use Alka Seltzer tablets as a source of carbon dioxide gas. (CS)

A science and social studies unit developed around rosin is described. Students develop an understanding of the processing of raw material from a plant source into a commercial product and how to protect wood from weathering by preparing, testing, and evaluating varnish and shellac for their wood protective qualities. (Author/DS)

Provides guidelines prepared by the National Science Teachers Association for the use and care of invertebrate and vertebrate animals in the classroom. Suggestions are made for conducting experimental and observational studies. (CS)

Described is a method of photographically recording the seasonal movements of the beach, and the equipment and details used in this method. Included is a method for determining current speed and instruction for construction of a tin can viewing box to be used in underwater sea form observations. (Author/DS)

Discussed is the intertidal region and the characteristics and adaptations of the organisms that live in that region. Several activities that involve the intertidal region are described, which reinforce the adaptive behaviors and forms of the organisms found in the intertidal region. (Author/DS)

Discusses the National Science Foundation's (NSF) National Science and Technology Week (NSTW), which provides opportunities for people to discover and express interest in science and technology. Includes information on teaching activities, business partnerships, and community involvement. (NB)

Explores early railroad expansion and ways in which new railroad technologies contributed to the development of the United States, particularly the western states. Activities help students understand how steam engines work, why stopping trains can be a lengthy proposition, why magnets will figure prominently into future trains, and why train…

Presents a hands-on activity as an excellent starting point for investigations related to the eye. Involves making a simple model of the vertebrate eye to illustrate the formation of an upside-down image on the retina by the lens. Links to investigations in numerous science disciplines including astronomy, genetics, biology, earth science, and…

Discusses "The Big Empty" or, the Great Basin. Suggests that it is not empty but rather a great ecosystem rich in plants, animals, and minerals. Presents information and activities to guide students in exploring the Great Basin in order to understand the ways in which such an arid and seemingly harsh environment can support so many…
