Solids, Liquids & Gases Incursion (Levels 5 & 6)

Theme: Science – Chemical Sciences
Level: 5 & 6

Students will investigate and compare the properties and behaviours of each state of matter with an emphasis on gas.


  • Discuss prior knowledge of matter and its states.
  • Identify states of matter and investigate the differences between them.
  • Observe that some matter is difficult to classify.
  • Create gas using chemical reactions and heat.
  • Use the property of flammability to test for the presence of gas.
  • Discuss demonstrations of changing state with a focus on heating and cooling gas.
  • Use candles to investigate heat rising and carbon dioxide production.


Victorian Curriculum: Content Descriptions


  • Solids, liquids and gases behave in different ways and have observable properties that help to classify them (VCSSU076)
  • Scientific understandings, discoveries and inventions are used to inform personal and community decisions and to solve problems that directly affect people’s lives (VCSSU073)
  • With guidance, pose questions to clarify practical problems or inform a scientific investigation, and predict what the findings of an investigation might be based on previous experiences or general rules (VCSIS082)
  • With guidance, plan appropriate investigation types to answer questions or solve problems and use equipment, technologies and materials safely, identifying potential risks (VCSIS083)
  • Decide which variables should be changed, measured and controlled in fair tests and accurately observe, measure and record data (VCSIS084)
  • Construct and use a range of representations, including tables and graphs, to record, represent and describe observations, patterns or relationships in data (VCSIS085)
  • Compare data with predictions and use as evidence in developing explanations (VCSIS086)
  • Suggest improvements to the methods used to investigate a question or solve a problem (VCSIS087)
  • Communicate ideas and processes using evidence to develop explanations of events and phenomena and to identify simple cause-and-effect relationships (VCSIS088)


“The children were very engaged and enjoyed consolidating the knowledge they already had as well as adding to it with new insights and practical demonstrations of what they had learned.” St. Andrews Christian College
