The demand for improving student interest in science has increased efforts toward teaching Einstein's theory of general relativity in schools. Research has already shown that teaching Einsteinian gravity at the secondary level is feasible, however, appropriate resources must be readily available for science teachers to make Einsteinian gravity…

The natural sciences, by their very nature, are based on the exploration of the physical world, and digital mobile devices are considered appropriate to support this exploration (Suárez et al., 2018) since they offer the tools that make this investigation more accessible but also ubiquitous (Crompton et al., 2017). Inquiry-based learning is a…

The "burning candle" experiment is used in middle school education programs to prove that air contains a component that is essential to burning (i.e., oxygen). The accepted interpretation taught by teachers in middle school is this: when burning occurs, oxygen is used up, creating an underpressure that causes a rise in water level inside…

Thinking scientifically consists of systematic observation, experiment, measurement, and the testing and modification of research questions. In effect, science is about measurement and the understanding of causation. Measurement is an integral part of science and engineering, and has pertinent implications for the human sciences. No measurement is…

The Ruben Flame Tube is named after H. Ruben, who published the demonstration experiment in "Annalen der Physik" in 1905. This article presents one of the many demonstrations the author uses to engage, motivate, and challenge his students.

The measurement of solar UV under water is not a simple process. In the underwater environment the difficulty of obtaining useable data is greatly amplified due to the optically complicated and at times unpredictable nature of water itself. The following practical exercise designed for use in the Year 11 and Year 12 Physics classroom aims to…

A take-home experiment kit has been developed to reinforce the concepts in a first year physics course that both on and off campus students from a variety of educational backgrounds can successfully use. The kit is inexpensive and is composed of easy to obtain items. The experiments conducted with the kit are directed experiments that require…
