Separating Mixtures

Author Pam Burt, West Moreton Anglican College, Queensland
Nature of the inquiry problem Students will investigate mixtures and separation techniques and apply this knowledge to develop ideas to makes better use of biomass.
Suitable year levels and subject areas Year 8 - 10 Australian Curriculum
Curriculum links

Mixtures, including solution, contain a combination of pure substances that can be separated using a range pf techniques (ACSSU113)

Identify and investigate issues involving numerical data collected from primary and secondary sources (ACMSP169)

Calculate mean, medians, mode and range for sets of data. Interpret these statistics in the context of data (ACMSP171)

Learning Objectives

Students will:

  • apply understanding of mixtures and separation techniques to the context of biomass waste reduction and process and interpret secondary data using statistical techniques
Student Learning Outcomes*

At the end of the inquiry students will:


  • describe techniques to separate pure substances from mixtures
  • analyse how the sustainable use of resources depends on the way they are formed and cycle through Earth's systems
  • Describe situations where scientific knowledge from different science disciplines and diverse cultures has been used to solve a real-world problem
  • communicate their ideas, methods and findings using scientific language and appropriate representations


  • identify issues  involving the collection of continuous data
  • calculate mean for data sets


  • students explain how social, ethical, technical and sustainable considerations influence the design of innovative and enterprising solutions to meet a range of present and future needs
