Curriculum content descriptions

use a particle model to describe differences between pure substances and mixtures and apply understanding of properties of substances to separate mixtures (AC9S7U06)

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