AC9S7U06 Year 7 Science

This Content Descriptor from Year 7 Science provides the specific knowledge and skills students should learn. Use it to plan lessons, create learning sequences, and design assessments that align with the Australian Curriculum v9.

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

Elaborations

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