This book, one of a series, focuses on science seen every day in homes and neighborhoods. The message of the series of books urges parents and children to spend time together, talk about stories, and learn together. The first part of each book presents stories appropriate for varying grade levels, both younger children and those in grades three…

A study conducted by high school advanced bacteriology students appears to confirm the hypothesis that the incremental administration of antibiotics on several species of bacteria (Escherichia coli, Staphylococcus epidermis, Bacillus sublitus, Bacillus megaterium) will allow for the development of antibiotic-resistant strains. (PEB)

Presented are some considerations relating to the problem of why human studies is still regarded as a new subject and why resistance to human studies as a new subject is so great. (PB)

The need for nutrition education to be given higher priority in science instruction in today's world is promoted. Nutrition is viewed as a significant problem for all persons in a personal sense and in a societal sense. (MP)

The article advocates the use of content topics, and by the use of appropriate enquiry process skills, the development of broad concepts which will encourage children to consider their attitudes in a broad range of issues and the part they can play in decisions about them. (Author/RE)

Described is the need to incorporate the concepts and applications of advanced composite materials into existing chemical engineering programs. Discussed are the justification for, and implementation of topics including transport phenomena, kinetics and reactor design, unit operations, and product and process design. (CW)

Described are demonstrations designed to reveal the important "nonsolvent" properties of water through its interaction with a toy called "Magic Sand" and other synthetic silica derivatives, especially those bonded with organic moities. The procedures for seven demonstrations along with a discussion of the effects are presented. (CW)

Presented are laboratory methods which allow the demonstration and determination of the diffusion coefficients of compounds ranging in size from water to small proteins. Included are the procedures involving the use of a spectrometer, UV cell, triterated agar, and oxygen diffusion. Results including quantification are described. (CW)

Presented is a set of procedures designed to check the design, ergonomics, illumination, function, optics, accessory equipment, and image quality of a microscope being considered for purchase. Functions for use in a petrology or mineralogy laboratory are stressed. (CW)

Court rulings have established three basic responsibilities school systems must meet in science programs: (1) inform students about the hazards they might encounter in a science class; (2) provide a safe learning environment and properly maintained equipment; and (3) ensure adequate supervision. Outlines a four-point school safety plan. (MLF)

To improve science instruction, districts need one individual who has a strong science background, leadership skills, communication skills, and a commitment to implementing a high-quality science program. Lists the job description of a science supervisor. (MLF)

Describes science activities for preschool through primary-grade children, focusing on goals of science education, science processes, and characteristics of high-quality science activities. Notes that hands-on activities explore scientific concepts such as volume, gravity, heat conductivity, and condensation. (KB)

Describes ways to incorporate science into events that typically happen during the school year, including the school carnival, school assemblies, open house, book fair, sports events, newsletters, field trips, schoolyard cleanup, career days, and parent-teacher conferences. Presents tips to encourage parents to support an improved science program…
