On Wednesday 14 August, Year 11 Chemistry students undertook their annual trip down to Coochin Creek to analyse the water quality. The students performed various tests to determine quantities such as dissolved oxygen , biological oxygen demand , salinity , pH , conductivity, water hardness and water temperature.The purpose of the excursion was to collect as much information as possible to determine the present quality of the water in Coochin Creek and to compare this data to data collected by the Caboolture Shire Council back in 1999. The students also collected water samples at different sites along the river which were analysed by the Analytical Chemistry Department at the University of the Sunshine Coast.
The University tested our samples for levels of phosphates, nitrates, nitrites, ammonia, thermo-tolerant coliforms and E.Coli. The final component of the Extended Experimental Investigation (EEI) required the students to design experiments to simulate the possible effects if a fertilizer manufacturing plant was allowed to be built on the banks of Coochin Creek. Throughout the EEI students investigated real life issues involving Chemistry. They used their chemistry knowledge and skills to make informed decisions.
