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…

Dale, Keith; Dale, Stephen G. – Teaching Science, 2018
The Australian Curriculum (n.d.) describes chemistry as having three interrelated strands, Science Inquiry Skills, Science as a Human Endeavour and Science Understanding. It also states "... the three strands of the Australian Curriculum: Science should be taught in an integrated way". This article will explore a model for integrating…

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…

Keeratichamroen, Wasana; Dechsri, Precharn; Panijpan, Bhinyo; Ruenwongsa, Pintip – Teaching Science, 2010
In any demonstration to students, producing light and sound usually ensures interest and can enhance understanding and retention of the concepts involved. A guided inquiry (Predict, Observe, Explain: POE) approach was used to involve the students actively in their learning about the explosive combustion of fine flour particles in air in the…

Yip, Din Yan – Teaching Science, 2009
Investigations that study the effect of heating on ascorbic acid are commonly performed in schools, but the conclusions obtained are quite variable and controversial. Some results indicate that heating may destroy vitamin C, but others suggest that heating may have no effect. This article reports an attempt to resolve this confusion through a…

King, Donna – Teaching Science, 2009
Nationally and internationally, context-based programs have been implemented in an attempt to engage students in chemistry through connecting the canonical science with the real world. In Queensland, a context-based approach to chemistry was trialled in selected schools from 2002 but there is little research that investigates how students learn in…

Drew, John – Teaching Science, 2008
In this article I explain why I wrote the set of teaching notes on Atomic Absorption Spectroscopy (AAS) and why they look the way they do. The notes were intended as a student reference to question, highlight and write over as much as they wish during an initial practical demonstration of the threshold concept being introduced, in this case…
