This guide, the first in a series of three, provides the intermediate science student and teacher an opportunity to review selected science concepts and processes through activities which emphasize the applicability of scientific knowledge in the professional world. The three components in this guide deal with (1) ecology (what marine science…

This guide, the third in a series of three, provides the Spanish-speaking intermediate science student and teacher an opportunity to review selected science concepts and processes through activities which emphasize the applicability of scientific knowledge in the professional world. The three components in this guide deal with (1) the scientific…

This activity manual is divided into 15 units which focus on: the nature of science; metric measurements; properties of matter; energy; atomic structure; chemical reactions; acids, bases, and salts; temperature and heat; readioactivity; mechanics; wave motion, sound, and light; static charges and current electricity magnetism and electromagnetism;…

Background information, lists of materials needed, and procedures are provided for 12 experiments which focus on various aspects of pollution and the environment. Topics considered in the investigations are: (1) solids in the air; (2) effect of air pollution on nylon; (3) measuring lung capacity; (4) an electrical smoke trap; (5) photosynthesis;…

The common links in language learning theory relating to school content areas are the notion of input comprehensible to the learner, the distinction between language usage and use, and the concept of cognitive/academic language proficiency in contrast with basic interpersonal communication skills. This suggests that a laboratory-based science…

During distributed virtual laboratory experiment sessions, a major problem is to be able to collect, store, manage and share heterogeneous data (intermediate results, analysis, annotations, etc) manipulated simultaneously by geographically distributed teammates composing a virtual team. The electronic notebook is a possible response to this…

The academy's zeitgeist--standards of scientic investigation--has recently come to the fore in the national arena as the dominant moral and intellectual framework for educational research. In this article, we explore the re-emergence of standards of scientific investigation as a significant shaping force in education and the scholarly culture,…

This document presents a secondary level physics unit which introduces students to the Wheatstone Bridge, its use in determining the value of unknown resistors, and the effects of wiring resistors in series or in parallel. (SL)

Presented is a secondary level physics unit which introduces students to electrical resistance in series and parallel combinations, use of the voltmeter and ammeter, wiring simple circuits, and writing scientific reports. (SL)

Describes a low priced ripple tank with accessories for use with an overhead projector as well as the assembly of a variable speed wave source. Photographs are included. (GH)

Introductory science has become a discovery course for the students at Phillips Exeter Academy (New Hampshire), who are above average in ability and motivation. The philosophy of the course is that it should serve a more humanizing function than the preparation of young technicians, and that this function is as important for the future scientist…

Fourteen basic experiments in mechanical engineering, intended for use at the sophomore level, are presented. The experiments are described as open-ended in order to give students the opportunity to discover the importance of stable operating conditions. The concept of experimentation is introduced and there is an interrelation between theory and…

Reported is a study to investigate the effects of a free-choice program on children's ability to interpret experiments, design simple investigations, and recognize variables that could affect the outcome of observed events. (Author/SA)

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…

An experimental solar heating system heats five modular classrooms at the Fauquier County High School in Warrenton, Virginia. The present report covers the operation, maintenance, and modifications to the system over the 1974-75 and 1975-76 heating seasons. The solar system has shown the capability of providing essentially 100 percent of the…
