The oscillating atmospheric CO[subscript 2] concentrations at Mauna Loa, on the island of Hawaii, Hawaii, United States of America, are Fourier transformed in order to extract the period of oscillations. Also well-known as the Keeling curve, CO[subscript 2] concentrations (in time series) at Mauna Loa oscillate in direct association with seasonal…

Simulations of physical systems are widely available online, with no cost, and are ready to be used in our classrooms. Such simulations offer an accessible tool that can be used for a range of interactive learning activities. The Jovian Moons Apple allows the user to track the position of Jupiter's four Galilean moons with a variety of…

This study describes how in-service teachers in the pre-vocational sector in Mauritius adopted specific strategies to overcome the language barrier in the learning of science (Van Driel, Verloop & de Vos, 1998). Students of form III were taught few basic ideas related to "Earth & Space" through the use of role play and ICT. The…

Describes how to fit binocular observations of the planets to a theoretical model of circular orbits using a modern computer spreadsheet, from which fundamental data about the solar system may be deduced. (AIM)

Describes how a spreadsheet is used to fit a circular orbit model to observations of Jupiter's moons made with a small telescope. Kepler's Third Law and the inverse square law of gravity are observed. (AIM)

"Io," one of four satellites of Jupiter, orbits its mother planet in roughly the same plane as Earth orbits the sun. Guidelines for collecting data about Io using a reflecting telescope, 35mm camera, and adapter are presented. A computer program used in studying Io's maximum distance from Jupiter is available. (DH)

Research has shown that technology-enhanced visualizations can improve inquiry learning in science when they are designed to support knowledge integration. Visualizations play an especially important role in supporting science learning at elementary and middle school levels because they can make unseen and complex processes visible. We identify 4…

Reviews a software planetarium package called "Sky Travel." Includes two audiovisuals: "Conquest of Space" and "Windows on Science: Earth Science"; and four books: "Small Energy Sources: Choices that Work,""Stonehenge Complete,""Uneasy Careers and Intimate Lives: Women in Science…
