Describes an activity used in the science methods class at the University of Wisconsin to bring preservice elementary teachers into appropriate contact with children and to give them the opportunity to try out a variety of materials and activities from the newer elementary science curricula. (JR)

Instructions (with diagrams and parts list) are provided for constructing an eye model with a pliable lens made from a plastic bottle which can vary its convexity to accommodate changing positions of an object being viewed. Also discusses concepts which the model can assist in developing. (Author/SK)

Reports using a closed-circuit television system for presenting the concept of homogeneous strain so the complete straining sequence can be followed from the initial state through progressively increasing strain ratios. Suggests photographing the screen for materials for student exercises. (DS)

Presented in chart format are items from over 200 suppliers of science education materials, including textbooks, tradebooks, program/resource materials, media, and laboratory and other equipment. Addresses of suppliers, grade level/subject area, and supplementary resources are also provided. Includes listing of firms providing sources but which…

This research news article on microelectronics discusses the scientific challenge the integrated circuit industry will have in the next decade, for designing the complicated microcircuits made possible by advancing miniaturization technology. (HM)

Describes different ways plastic containers can be recycled for use in the science classroom. Uses of clear, opaque, and translucent plastic products in the science classroom are described. (DS)

Presents resource materials and references intended to guide physicists, astronomers, and physics teachers to some of the literature and other teaching aids that deal with new particles. (HM)
