McPherson, Heather – Teaching Science, 2018
In this article, the author describes a chemistry gas experiment that she developed with the intent of integrating inquiry and Problem-Based Learning (PBL). The lab activity follows the principles of Ambitious Science Teaching (AST). Teachers (1) engage students with important science ideas, (2) elicit students' ideas while making visible what…

Sultana, Khalida; van Rooy, Wilhelmina – Teaching Science, 2009
Extracting DNA from fruit and vegetables provides students with hands-on opportunities to engage with a visualisation of genetic material that can later be supported by ICT and practical model making. Here is a quick, cheap and easy way to extract DNA from strawberries that avoids the mess involved in other DNA extractions, such as from dried…

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…
