Solids & Liquids Incursion (Levels 3 & 4)

Theme: Science – Chemical Sciences
Level: 3 & 4

Students will investigate the changes that occur between solid and liquid matter when adding and removing heat.


  • Discuss prior knowledge of matter and its states.
  • Investigate the special properties of solids and liquids.
  • Classify materials based on state of matter and recognise that some materials do not fit nicely.
  • Explore how different solids can be bent.
  • Observe surface tension in liquids.
  • Investigate the change in viscosity of a liquid due to temperature.
  • Use a thermometer to measure and compare temperatures.
  • Compare evaporation of different liquids.
  • Test the melting point of wax, chocolate, citric acid and sugar.
  • Conduct experiments safely in a group.


Victorian Curriculum: Content Descriptions


  • A change of state between solid and liquid can be caused by adding or removing heat (VCSSU059)
  • Natural and processed materials have a range of physical properties; these properties can influence their use (VCSSU060)
  • Science knowledge helps people to understand the effects of their actions (VCSSU056)
  • With guidance, identify questions in familiar contexts that can be investigated scientifically and predict what might happen based on prior knowledge (VCSIS065)
  • Suggest ways to plan and conduct investigations to find answers to questions including consideration of the elements of fair tests (VCSIS066)
  • Safely use appropriate materials, tools, equipment and technologies (VCSIS067)
  • Use formal measurements in the collection and recording of observations (VCSIS068)
  • Use a range of methods including tables and column graphs to represent data and to identify patterns and trends (VCSIS069)
  • Compare results with predictions, suggesting possible reasons for findings (VCSIS070)
  • Reflect on an investigation, including whether a test was fair or not (VCSIS071)
  • Represent and communicate observations, ideas and findings to show patterns and relationships using formal and informal scientific language (VCSIS072)
