Presents a diversity of concrete experiences that can be used with eggs for young elementary age students. Includes procedures and material list for several activities that are hands-on and interdisciplinary in nature. (ML)

Provides examples of science experiments and demonstrations that are centered on the theme of eggs. Activity explanations include: (1) the floating egg; (2) egg-in-the-bottle; (3) walking on eggs; and (4) egg balancing. (ML)

Lists and explains the major characteristics of water. Compares water's molecular structure and its temperature-related properties with four other lightweight molecules. Discusses why water is considered the universal solvent. (ML)

Procedures for dying and mordanting wool fibers and for preparing dyes from red onion skin, purple cabbage, pine needles, and purple lilac are presented. Information on the history of dyes and on how dyes work is included. (JN)

Suggests using ring doves in the classroom for observing behavior patterns and the entire reproductive cycle. Requirements for space, food, and care are minimal and easily obtained. Students can observe: male participation in nest-building; care of young; and (using candlelight) embryos and heartbeats because of the thin egg shells these birds…

Describes elementary school science trade books written in Spanish. Topics considered in these books include: animal life; astronomy; biology; earth sciences; mathematics; general science; and general technology. (DH)

Fifth- and sixth-grade students (N=154) participated in a study which found that cooperative learning situations, compared to individualistic ones, promoted more positive cross-sex and cross-handicap relationships. It was also found that males achieved higher and had more positive attitudes toward science than did females. (Author/JN)

During the 1982-83 school year, 252 elementary science teachers were surveyed to determine the status of science teaching in their schools and to indicate what could be done to improve science education. Selected results from this survey are reported and discussed. (JN)

A pilot program providing a comprehensive humane education curriculum is described. Packets containing instructional material on animal classification, pet care, wildlife, animal communication, and human activism are provided to teachers. In addition, school visits make it possible to demonstrate the activities, and motivate teachers to make…

Describes activities involving Bernoulli's principle which allows students to experience the difference between knowledge and scientific understanding. Explanations for each of the activities (using such materials as wooden spools, straws, soda bottles and table tennis balls) and explanations of phenomena in terms of Bernoulli's are provided. (BC)

This article: (1) explains the respiratory patterns of several freshwater insects; (2) describes the differences and mechanisms of spiracular cutaneous, and gill respiration; and (3) discusses behavioral aspects of selected aquatic insects. (ML)

Success of the Murch Elementary School (Washington, DC) science fair is due to many factors which are applicable to other schools. Suggestions, ideas, and hints are given in this description of the school's program. Projects with an electrocardiogram, water weeds, and preserving ice are also discussed. (DH)

Suggests the use of a body puzzle as a student-centered and economic way of teaching human anatomy. Provides a full page diagram of the body with illustrations of selected organs. Lists activities that can serve as the basis for inquiry into the structure and function of the human body. (ML)

Teachers can help children understand that sound is caused when something vibrates by using the suggested activities to help teach them to see, hear, and feel the vibrations all around them. Suggests reinforcing the lesson by having the children create musical instruments out of simple materials. (JN)

Suggests various observations that can be made while at a zoo, including behavior of animals, adaptations to special environments, locomotion, food type, and physical characteristics. Provides a sample data sheet for animal observations, citing the usefulness of organized observation. (JM)
