A new educational simulation tool designed for the generic study of wireless networks, the Wireless Fidelity Simulator (WiFiSim), is presented in this paper. The goal of this work was to create and implement a didactic tool to improve the teaching and learning of computer networks by means of two complementary strategies: simulating the behavior…

Purpose: The purpose of this paper is to present an improved concept of software-based laboratory exercises, namely a Virtual Laboratory for Engineering Sciences (VLES). Design/methodology/approach: The implementation of distance learning and e-learning in engineering sciences (such as Mechanical and Electrical Engineering) is still far behind…

The Pacific Region Junior Science and Humanities Symposium has operated for 14 years as a region of the National Junior Science and Humanities Symposium. In response to the trend among professional science and science education societies to include both formal research report presentations and informal poster presentations, the Pacific Region…

This book contains over 30 investigations and activities that can be used or adapted for science fair projects. It outlines basic techniques and procedures that can be applied to zoological investigations. Projects and activities described include: finding out how many different kinds of insects and other arthropods live in nearby fields and…

Many science educators emphasize the need and importance of hands- and minds-on education in science. This document provides numerous hands-on science activities for students and tips for parents and teachers to help take some of the stress out of hands-on projects. Some of the suggestions made to teachers are related to the following concerns:…

Describes the construction of a demonstration to show optical activity of table syrup. (Author/CP)

Describes the construction of a flexible coupled-cavity interferometer for student use. A helium-neon laser and phonograph turntable are the main components. Lists activities which may be performed with the apparatus. (Author/CP)

Discusses instrumentation and describes such research areas as the albedos of the brighter planets, rotation rates and atmospheres of the larger and brighter satellites, brightness changes of outer planets, asteroid rotation rates, and variable stars. (GS)

The function, design, and ground station requirements of the AMSAT-OSCAR non-commercial space satellite system are described, and various experiments designed for direct student participation in space communications are provided in this text primarily written for the science educator. Six chapters include: (1) an introduction to general satellite…

IDEAS FOR SCIENCE INVESTIGATIONS FOR SECONDARY SCHOOL STUDENTS ARE DESCRIBED. IN PART I THE STUDENT IS INTRODUCED TO THE IDEA OF THE PROJECT-TYPE INVESTIGATION AND IS GIVEN A GENERAL OVERVIEW OF THE MANUAL. A SECTION WHICH IS WRITTEN FOR THE TEACHER INCLUDES A DISCUSSION OF (1) EDUCATIONAL VALUES DERIVED FROM INDIVIDUAL INVESTIGATIONS, AND (2) THE…

THIS GUIDE FOR THE SCIENCE FAIR PARTICIPANTS BEGINS WITH A CHAPTER ON THE NATURE OF SCIENCE, AND THE SCIENCE FAIR, AND CONTINUES THROUGH THE FIVE CHAPTERS OF PART ONE, PLANNING AND EXECUTING YOUR PROJECT, TO EXPLAIN THE DETAILS INVOLVED IN SELECTING, DEVELOPING, AND EXHIBITING A PROJECT. PART II OF THE VOLUME CONSIDERS THE STRUCTURE OF SCIENCE…

Examines the practice of holding competitive science fairs. Offers suggestions on judging, competition and recognition, student participation, and alternative experiences. (MA)

Suggestions for developing creative and original science fairs include trying new categories, issuing a challenge, and involving the community. (DF)

Describes: (1) various research studies of the mid-ocean ridges; (2) how money and facilities are made available for these studies; and (3) the prospect for future ocean floor studies. Indicates that a presidential proclamation (Exclusive Economic Zone) has extended United States boundaries 200 nautical miles seaward, adding new exploration sites.…
