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…

Describes an experimental project on boomerangs designed for an undergraduate course in classical mechanics. The students designed and made their own boomerangs, devised their own procedures, and carried out suitable measurements. Presents some of their data and a simple analysis for the two-bladed boomerang. (Author/MLH)

Presents two calculations of the probability of detection of an interstellar comet, under the hypothesis that such comets would escape from comet clouds similar to that believed to surround the sun. Proposes three problems, each of which would be a reasonable term project for a motivated undergraduate. (Author/MLH)

Describes activities to stimulate school astronomy programs. Topics include: counting stars; the Earth's centripetal force; defining astronomical time; three types of sundials; perceptions of star brightness; sunspots and solar radiation; stellar spectroscopy; number-crunching and the molecular structure of the atmosphere; the Earth-Moon common…

Develops a simplified electrostatic model of the heart with conduction within the torso neglected to relate electrocardiogram patterns to the charge distribution within the myocardium. Suggests its application to explanation of Coulomb's law in general physics. (CC)

Shows how model rocketry can be included in physics curricula. Describes rocket construction, a rocket guide sheet, calculations and launch teams. Discusses the relationships of basic mechanics with rockets. (CW)

Presents two demonstrations using the overhead projector: (1) describes how to build a projecting voltmeter and presents uses for the classroom; and (2) investigates the color of fluorescent solutions by studying the absorption and transmission of light through the solutions. (MVL)

Contemporary instructional approaches expect students to be active producers of knowledge. This leads to the need for creation of instructional tools and tasks that can offer students opportunities for active learning. This study examines the effect of a computational experiment as an instructional tool-for Grade 12 students, using a computer…

NASA will launch Space Station Freedom piece by piece in the cargo bay of space shuttles. The process is scheduled to start in 1995 and be completed in 1999. This pamphlet presents factual information and accompanying hands-on science activities concerning the following aspects of the project: (1) the space shuttle's role in transport; (2) the…

Describes the development of and activities used with rubber powered paper vehicles as science projects and instructional devices in junior high and high school science classes. Includes plans and instructions for building the "Lou-Vee-AirCar." (CW)

Provides a refinement to the Harvard Project Physics Course handbook exercise "Stepwise Approximation to an Orbit." (CP)

This guide contains Parts III and IV of the students' guide to the first year of the three-year integrated biology, chemistry, and physics courses being prepared by the Portland Project Committee. Part III is titled "Energy and Work" and Part IV is titled "Ecology." (GR)

Lists changes which have been made in second edition and explains the philosophy upon which the alterations were based. (CP)

Discusses the development of a model for implementing Project Physics without the use of physics teachers. Indicates that students can study Unit 3, independently, with the aid of the supplementary materials produced in this project and achieve as well as the average student in a teacher-taught class. (CC)
