An astronomy "experiment" composed of three parts is described in the article. Being given necessary data a simple model of inner planets of the solar system is made in the first part with planets' circular orbits using appropriate scale. In the second part revolution of the figurines used as model representations of the planets along…

In this paper we present the "Sky on Earth" project funded in 2008 by the Italian Ministry of Instruction, Research and University, inside its annual public outreach education program. The project's goal was to realise a stable and open-access astronomical garden, where children, teachers and citizens could be engaged in investigations…

Shadows can be found easily everywhere around us, so that we rarely find it interesting to reflect on how they work. In order to raise curiosity among students on the optics of shadows, we can display the shadows in 3D, particularly using a stereoscopic set-up. In this paper we describe the optics of stereoscopic shadows using simple schematic…

Experiments are described on collisions between two billiard balls and between a bat and a ball. The experiments are designed to extend a student's understanding of collision events and could be used either as a classroom demonstration or for a student project.

This article describes the Lissajous generalized figure and the original instrument for its investigation. Two specially prepared electrodynamic loudspeakers--a horizontal and a vertical--cause oscillations in two mirrors. It is possible to precisely control the motion of the mirrors, achieve a high frequency of oscillation and investigate…

What follows is a description of a theoretical model designed to calculate the playing frequencies of the musical pitches produced by a trombone. The model is based on quantitative treatments that demonstrate the effects of the flaring bell and cup-shaped mouthpiece sections on these frequencies and can be used to calculate frequencies that…

The measurement of the force acting between two parallel, current-carrying wires is known as Ampère's experiment. A mechanical balance was historically employed to measure that force. We report a simple experiment based on an electronic precision balance that is useful in clearly showing students the existence of this interaction and how to…

An inexpensive and easily implemented device to measure wind velocity is proposed. This prototype has the advantage of being able to measure both the speed and the direction of the wind in two dimensions. The device utilizes a computational interface commonly referred to as a "mouse." The mouse proposed for this prototype contains an…

Who owns a new science course once it has been developed? If teachers teach a course in their own way, does this transformation improve or deform it? The development of "Advancing Physics" provokes some fresh thought about these questions. (Author/MM)

Described is the present education of secondary school physics teachers in the Netherlands. (CS)

Some students may find physics hard, but wouldn't it be more difficult to be taught it in a foreign language? The project described here uses English to teach physics to Spanish secondary school students. The students perform just as well in physics while their results in English improve markedly.

Presents background information related to astronomy for high school students. Discusses the differences between astronomy and astrophysics, and the employment of the astronomy graduates. Lists degree programs in astronomy and related subjects in an appendix. (YP)

The important role of the digital computer in education is outlined. The existing Indian situation and needs and the scope of the Computer Literacy And Studies in Schools (CLASS) program are briefly discussed. (Author/KR)

Described is the undergraduate curriculum in physics and its relationship to astronomy at Cambridge University. Discussed are the astronomical research and research establishments at Cambridge. Personal views of a student on the postgraduate research being done at Cambridge are also included. (KR)

Describes the structure and content of a four-year physics/microcomputer degree program at the University of Surrey. (SK)
