Elaborations
- • Elaboration using representations of particles to show the difference between samples of pure substances and mixtures, and identifying examples of each
- • Elaboration examining different solutions and identifying the solvent and solute
- • Elaboration investigating and using a range of physical separation techniques such as filtration, decantation, evaporation, crystallisation, chromatography and distillation
- • Elaboration exploring and comparing separation methods used in a variety of situations such as in the home, recycling industries and purifying water
- • Elaboration analysing how the physical properties of substances in mixtures, such as particle size, density or volatility, determine the separation technique used
- • Elaboration investigating separation techniques used by First Nations Australians, such as hand-picking, sieving, winnowing, yandying, filtering, cold-pressing and steam distilling
