Lim, Kieran F.; Long, John M.; White, Peta J.; Bentley, Ian D. – Teaching Science, 2019
The Advancing Science and Engineering through Laboratory Learning (ASELL) for Schools program has been instrumental in getting schools across Australia to reconsider the effectiveness of the laboratory learning activity (LLA) in science education. In Victoria, the ASELL for Schools project has collaborated with another nationally funded program,…

Lim, Kieran F. – Teaching Science, 2019
The use of the valence-shell electron-pair repulsion (VSEPR) model is essential for understanding aspects of bonding, molecular dipoles, inorganic complex ions, isomerization and stereochemistry, the lock-and-key mechanism for enzyme activity, and many other ideas. This paper describes how different approaches can be used to help students learn…

Lim, Kieran F. – Teaching Science, 2012
The common question of why the tetrahedral angle is 109.471 degrees can be answered using a tetrahedron-in-a-cube, along with some Year 10 level mathematics. The tetrahedron-in-a-cube can also be used to demonstrate the non-polarity of tetrahedral molecules, the relationship between different types of lattice structures, and to demonstrate that…

Lim, Kieran F. – Teaching Science, 2012
Titrations are common laboratory exercises in high school and university chemistry courses, because they are easy, relatively inexpensive, and they illustrate a number of fundamental chemical principles. While students have little difficulty with calculations involving a single titration step, there is a significant leap in conceptual difficulty…

Lim, Kieran F.; Dereani, Marino – Teaching Science, 2010
Nuclear magnetic resonance (NMR) spectroscopy is an important tool in the structural analysis of both organic and inorganic molecules. Proton NMR spectra can yield information about the chemical or bonding environment surrounding various protons, the number of protons in those environments, and the number of neighbouring protons around each…
