States of Matter (Levels 3/4)

Theme: Science – Chemical Sciences
Level: 3/4

In this engaging 90-minute incursion, students have a fun time investigating solids and liquids and how heat can create changes between these states. Students also learn about materials that do not fit neatly into the categories of either solid or liquid. From exploring the melting point of various materials to testing how different solids can be bent, this incursion is packed full of fun activities that extend their knowledge of the states of matter. Our passionate science educators carefully guide students through each activity, prompting students to predict, observe and reflect on each activity.


Learning outcomes

  • 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

  • Science knowledge helps people to understand the effects of their actions (VCSSU056);
  • 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);
  • 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).

“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

“The incursion was the perfect introduction to our unit on materials and linked with the Australian Curriculum perfectly. The students had a wonderful time and learned so much.”
