Science Extension Success<\/strong><\/h4>\n

On Lunchtime of Friday 9 September the Year 12 Science Extension students presented their long term projects to the students and teacher on a wonderful session held in the School Library. The six students, Clare Crawford, Emily Feller, Olivia Jarvie, \u00a0Dakota Kedzier-Hurst, Jemimah O’Brien and India Poiner had an amazing diversity of projects that they have each been researching over the year.<\/p>\n

The Year 12 Science Extension course is a fantastic way for Year 12 students to engage with scientific project work on their chosen topic and get to explore different methodologies that best test their scientific ideas. The poster presentations of their work will be on display in the Joan Freeman Building.<\/p>\n

Two teams of Year 12 Chemistry students have \u201cdropped the base\u201d and risen to fame at the National Titration Competition held at UNSW on Saturday 10\u00a0September.<\/p>\n

Titration is a technique used by chemists to determine the exact concentration of a chemical solution. Year 12 students study this technique for determining acid and base concentrations in the HSC Course, and the competition provides an excellent opportunity to practise analytical techniques in the laboratory. As the concentration of one of the solutions is known, we can use a chemical reaction between this and the unknown solution, in the presence of a coloured indicator, to determine its concentration. Students must practise specific rinsing techniques and use analytical glassware appropriately to find out the most accurate concentration.<\/p>\n
