AC9S7U06
Chemical sciences
use a particle model to describe differences between pure substances and mixtures and apply understanding of properties of substances to separate mixtures
Elaborations
- AC9S7U06_E1using representations of particles to show the difference between samples of pure substances and mixtures, and identifying examples of each
- AC9S7U06_E2examining different solutions and identifying the solvent and solute
- AC9S7U06_E3investigating and using a range of physical separation techniques such as filtration, decantation, evaporation, crystallisation, chromatography and distillation
- AC9S7U06_E4exploring and comparing separation methods used in a variety of situations such as in the home, recycling industries and purifying water
- AC9S7U06_E5analysing how the physical properties of substances in mixtures, such as particle size, density or volatility, determine the separation technique used
- AC9S7U06_E6investigating separation techniques used by First Nations Australians, such as hand-picking, sieving, winnowing, yandying, filtering, cold-pressing and steam distilling
