Baking cakes with different recipes can provide an exercise in the application of the scientific method, illustrating the need to vary only one ingredient at a time for correct derivation of conclusions. This experiment, most likely to be performed at home, compares a cake flour with flours from durum wheat, rice and cornflour (gluten-free…

This research focuses on the use of ethical frameworks as a pedagogical model for socio-scientific education in implementing the "Science as a Human Endeavour" (SHE) strand of the Australian Curriculum: Science in a Year 10 biology class in a Christian college in metropolitan Perth, Western Australia. Using a case study approach, a mixed…

Modern drug discovery programs require the contribution of researchers in a number of specialist areas. One of these areas is structural biology. Using X-ray crystallography, the molecular basis of how a drug binds to its biological target and exerts its mode of action can be defined. For example, a drug that binds into the active site of an…

In October 2012, two students from the Australian Science and Mathematics School and two from Yankalilla Area School were selected to travel to Olavarria, Argentina in order to compete in the 6th International Earth Science Olympiad (IESO). It was an opportunity for individuals with a passion for Earth science to come together from 17 countries to…

Is there a crisis in Australian science and mathematics education? Declining enrolments in upper secondary Science and Mathematics courses have gained much attention from the media, politicians and high-profile scientists over the last few years, yet there is no consensus amongst stakeholders about either the nature or the magnitude of the…

Scientific visualisations such as computer-based animations and simulations are increasingly a feature of high school Science instruction. Visualisations are adopted enthusiastically by teachers and embraced by students, and there is good evidence that they are popular and well received. There is limited evidence, however, of how effective they…

This paper argues that, despite its difficulties, climate change can (and perhaps needs to) be taught rigorously to students by enquiry rather than through transmission and that such a method will enable students to make judgments on other issues of scientific controversy. It examines the issues and barriers to the teaching of climate change,…

A variety of factors are associated with students' achievement in secondary school physics, including cohort size--the total number of students studying Physics in the school--and socioeconomic status. Earlier studies also showed boys achieving better in Physics, while more recent research has shown better results for girls. Statistical…

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…

Smartphones are used widely by the general public and students. They are one of the most popular and easily accessible technologies. These devices were originally designed as a means of communication. However, they have evolved into a mobile computing platform with built in sensors and the ability to access a vast number of applications. This…

Research methods is perceived as a technical and difficult topic by some students. Using role-play to teach it can make it more accessible, meaningful and engaging. Role-playing the familiar roles of customer and waiting staff at a restaurant and discussing the variables that may affect the size of tips can help students to learn some of the key…

Nanotechnology is guided by the assumption that with the ability to shape or re-shape at the molecular level, we could manipulate the physical world. Some speculate that this ability will be the beginning of the next technological revolution. Hence, an aim of secondary science education should be the development of scientifically literate citizens…

This study investigated 438 Year 10 students (15 and 16 years old) from Western Australian schools, on their understanding of the greenhouse effect and climate change, and the sources of their information. Results showed that most students have an understanding of how the greenhouse effect works, however, many students merge the processes of the…

Increasingly, children today are becoming disconnected from the natural environments resulting in a diminished sense of self, place and community. In an attempt to find out their perceptions, attitudes and values about the natural world, twenty-five Year 6 and 7 students from a northern Adelaide primary school participated in a nature-play case…

The fatal effect of the Hendra virus was noticed first in Queensland, Australia in 1994 when several horses died from an "unidentified cause". This was followed by the death of trainers and veterinarians called to assist affected horses. It is now known that the "unidentified cause", is a virus harboured in native Australian…
