Low, David; Wilson, Kate – Teaching Science, 2017
On entry to university, high-achieving physics students from all across Australia struggle to identify Newton's third law force pairs. In particular, less than one in ten can correctly identify the Newton's third law reaction pair to the weight of (gravitational force acting on) an object. Most students incorrectly identify the normal force on the…

Preston, Christine – Teaching Science, 2017
Familiar toys can be used to scaffold young children's learning about basic physics as well as guide scientific inquiry. Teachers looking for resources to engage young children and develop science inquiry skills need look no further than the toy box. In this two-part activity, children first construct a Lego┬« car and use it to explore the effects…

Massalha, Taha – Teaching Science, 2016
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…

Scherer, Nathaneal; Cousins, Aidan – Teaching Science, 2016
One of the important questions for any educator is, "How can I teach difficult and abstract concepts in a way that connects with students' real life?". This is especially true in the senior years, when students are often confronted with ideas that don't appear relevant to their lives, are primarily explainable using mathematics rather…

Cheng, Meng-Fei; Cheng, Yufang; Hung, Shuo-Hsien – Teaching Science, 2014
Based on our experience of teaching physics in middle and senior secondary school, we have found that students have difficulty in reasoning at the microscopic level. Their reasoning is limited to the observational level so they have problems in developing scientific models of magnetism. Here, we suggest several practical activities and the use of…

Schouten, Peter W.; Sharma, Ashok; Burn, Stewart; Goodman, Nigel; Parisi, Alfio; Downs, Nathan; Lemckert, Charles – Teaching Science, 2013
The emissions of various types of greenhouse gases (GHGs) from natural and industrial sources are undergoing a great deal of scrutiny around the world. The three main GHGs that are of most concern are carbon dioxide (CO[subscript 2]), nitrous oxide (N[subscript 2]O) and methane (CH[subscript 4]). CO[subscript 2], N[subscript 2]O and CH[subscript…

Sandoval, Christopher – Teaching Science, 2013
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.

Schouten, Peter; Parisi, Alfio; Downs, Nathan – Teaching Science, 2009
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…

Turner, Joanna; Parisi, Alfio – Teaching Science, 2008
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…

Downs, Nathan; Parisi, Alfio; McDonnell, Brendan; Thornton, Peter – Teaching Science, 2008
The article presents a technique to measure the ultraviolet index using a personal hand-held ultraviolet meter to illustrate concepts of physics. Measurements of the erythemally effective (sun-burning) direct solar beam, diffuse skylight, and total global ultraviolet irradiance are converted to daily ultraviolet index measurements. Daily…
