HSC Chemistry Excursion 2015
Kickstart at University of Sydney
The Chemistry excursion to the University of Sydney has broadened my understanding about the different chemical equipment used in forensic analysis. It was amazing to see first-hand investigations such as gas-liquid chromatography, high performance liquid chromatography, AAS and mass spectroscopy.
The diagrams and text shown in the textbooks are great but we saw even more detailed information in regards to the use, benefits and limitations of these techniques and the structure of the machines themselves. The class also had the opportunity to learn information from real forensic scientists and participate in many interesting experiments. The diverse range of titrations (e.g. for hard water testing) had allowed me to improve my skills and learn more diverse ways to undertake investigations throughout all the modules in my HSC course. The day was attended by Jennifer Arapakis, Luca Borean, Simone Chen, Rayza De Souza, Gabrielle Hachem, Chloe Hicks, Katelyn Hoy, Phoebe Josephs, Nivetha Mahesan, Yvette Mangani, Anastasia & Stephanie Morakeas , Melissa Neckovska, Natalia Sabatino, Aliesha Selvaraj, Eugenia Simoes and Anita Su.
The overall highlight of my excursion for my peers and I was the opportunity to expand our knowledge about the experiments we have studied at school. This also included the chance to use the gel electrophoresis equipment (that is used to determine the DNA of a specific individual) and the gas liquid chromatography & high performance liquid chromatography machines that determine the unknown substances present in a solution. The titrations were also really helpful as they engaged each student and allowed them to hone their skills to find the equivalence point for a variety of reactions.
