The Mathematics and Science Center serving five school districts in Richmond, Virginia, has developed devices and materials that teachers can borrow to produce mini-gardens in the classroom. Article gives directions for construction of a soil mixer and root-view box. (BR)

This second resource document on low-cost equipment contains designs of equipment for science and technology education using inexpensive materials. Part one contains 46 items suitable for construction in a school whereas part two consists of 20 designs which are more suitable for construction by a school with a well-equipped workshop and trained…

Civil lawsuits brought for injuries to students are a source of growing concern for teachers, and especially for science teachers. This paper outlines some basic principles by which science teachers may protect themselves from lawsuits, before and during the time that students are engaged in experiments or lab work. Courts in this country have…

This report contains statistical data from the Annual Survey of Scientific and Engineering Expenditures at Universities and Colleges, FY 1982. The data represent science and engineering (SE) expenditures for separately budgeted research and development (R&D). The phrase "separately budgeted R&D expenditures" refers to current…

Scientists/engineers from industry, universities, and government met to: review the status of scientific instrumentation in university research laboratories; explore new approaches to alleviating problems within existing budgetary constraints; and suggest ways for the National Research Council (NRC) to help. Federal agency, corporate, and…

Presented are statistical data from the Annual Survey of Scientific and Engineering Expenditures at Universities and Colleges, FY 1983. These data represent science and engineering (SE) expenditures for separately budgeted research and development (R&D). The phrase "separately budgeted R&D expenditures" refers to current fund…

Presented is a discussion of the events of the 20-year lapse between the invention of the pile in 1800 by Volta, and Hans Christian Oersted's famous definitive paper "Effects of a Current of Electricity on the Magnetic Needle." Students are thus enabled to appreciate the climate of the time and the manner and significance of Oersted's…

This paper focuses on the search for electromagnetic induction from 1820 to 1831 and the efforts by Augustin Fresnel's colleague, Andre Marie Ampere, in electric and magnetic induction. Faraday's work is discussed with excerpts from his diary on electromagnetism. A variety of different experiments by researchers including Francoise Jean Arago,…

This paper focuses on Michael Faraday's experimental research in electricity in the 1830's. Historical notes related to his work are included as well as experiments, his objectives, and illustrations of equipment for the experiments. Examples from his diary are given so that students can attempt to emulate his honest and systematic manner of…

This study describes children's learning in a free-choice environment. Teacher controlled instruction is minimized and children participate in a wide variety of science activities with equipment that is selected by each individual student. The study occurs within an elementary school's Science Enrichment Center and the children work on the…

The first part of this paper addresses the following topics: (1) the usefulness of microcomputers; (2) applications for microcomputers in analytical chemistry; (3) costs; (4) major microcomputer systems and subsystems; and (5) which microcomputer to buy. Following these brief comments, the major focus of the paper is devoted to a discussion of…

This safety guide for elementary school science teachers who plan science activities or laboratories for their students, presents information in the form of a flip chart that can be posted in the classroom and referred to in an emergency. Space is provided for emergency telephone numbers. A safety checklist is given for the teacher. Topics…

This laboratory guide for college chemistry students illustrates scientific equipment used in introductory chemistry courses. Common laboratory procedures are diagrammed with the intention of promoting the safe use of equipment. An index is included to facilitate finding the necessary information. (SA)

This document contains 20 devices which can be made by junior high and high school students. The products of these student projects can be employed in the study of the environment and range in topic from the study of biochemical oxygen demand in water to the construction of a back pack. Materials used in each project are generally readily…
