Natural & Processed Materials Incursion (Levels 3/4)

Theme: Science – Chemical Sciences
Level: 3/4
Students will use models and experiments to investigate how sudden geological changes and extreme weather can affect the earth’s surface.


  • Discuss prior knowledge of materials and where they come from (e.g. animal, plant or rocks and minerals);
  • Identify raw and processed materials;
  • Consider how the properties of materials affect management of waste or can lead to pollution;
  • Make and test a material that appears and acts like glass and plastic and is left for children to do further tests;
  • Investigate different materials for properties of insulating ability, water absorption and strength;
  • Measure and record results from various tests;
  • Observe a demonstration of the property of fire resistance in different fabrics.

Victorian Curriculum: Content Descriptions

  • People use science in their daily lives (VCSSU041);
  • Respond to and pose questions, and make predictions about familiar objects and events (VCSIS050);
  • Participate in guided investigations, including making observations using the senses, to explore and answer questions (VCSIS051);
  • Use informal measurements in the collection and recording of observations (VCSIS053);
  • Compare observations and predictions with those of others (VCSIS054);
  • Represent and communicate observations and ideas about changes in objects and events in a variety of ways (VCSIS055);
  • Science knowledge helps people to understand the effects of their actions (VCSSU056);
  • 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).
