Our Year 12 HSC Chemistry students recently undertook an enriching academic excursion to Charles Sturt University (CSU) Wagga, where they experienced the rigour and excitement of university-level scientific investigation.

The visit provided students with access to advanced laboratory facilities and professional analytical equipment, allowing them to extend their HSC studies beyond the classroom. Under the guidance of university academics and laboratory technicians, students engaged in a series of experiments designed to deepen their understanding of key syllabus concepts while developing refined practical skills.

A central focus of the day involved investigating acid–base chemistry through precise titrations and digital pH analysis. By carefully measuring solution behaviour and analysing neutralisation reactions, students strengthened their understanding of quantitative chemical analysis.

Students were also introduced to sophisticated analytical techniques. Using Atomic Absorption Spectrophotometry (AAS), they analysed trace concentrations of metallic elements with high precision, gaining insight into how chemistry is applied in food sciences. Through UV–VIS spectrophotometry, students measured light absorbance to determine equilibrium constants, reinforcing their understanding of reversible reactions and dynamic equilibrium.

A particularly exciting addition to this year’s excursion was the incorporation of Infrared (IR) spectroscopy and Nuclear Magnetic Resonance (NMR) spectrometry to test for the presence of organic compounds. This marks the first time this experimental component has been delivered as part of this HSC Chemistry study, providing students with authentic exposure to techniques widely used in pharmaceutical, forensic and research laboratories. The opportunity to interpret spectral data significantly enhanced their analytical thinking and bridged the gap between theory and real-world chemical investigation.

Beyond the laboratory experience, the excursion also provided students with valuable insight into university life and potential post-HSC study pathways in science and related disciplines at CSU.
