As part of the Year 12 Integrated Science Unit 3 program students complete a study of ecology. Three classes attended the 15 March excursion to the Canning River Eco Education Centre (CREEC) which allowed students to observe the practical implications of these studies in ecology. This involved visiting the Kent Street Weir to compare the living (biotic) and non-living (abiotic) factors of the ecosystem and analyse how the weir has impacted upon the natural environment.
This opportunity provided students with a truly authentic learning experience, as the upstream side of the river was experiencing an algal bloom – one of the greatest negative effects of human impact which causes extensive problems including fish kill. Students measured the abiotic factors using probes (temperature, pH and salinity), turbidity tubes and phosphate test kits to identify differences in the ecosystems.
The excursion encouraged students to have a great time outdoors, actively involved in hands-on, real life science.
