BIOLOGY EXCURSION
The Stage 1 Biology class stepped out of the lab to conduct some practical sampling techniques at Burra Gorge. Several sites were selected through the Worlds End Reserve, which included running streams and billabongs connecting the Burra Creek. Students tested abiotic factors to determine water quality (pH, dissolved oxygen, turbidity and temperature) and carried out transect studies to survey the different species inhabiting the ecosystem.
