Natural & Processed Materials Incursion (Levels 3 & 4)

Theme: Science – Chemical Sciences
Level: 3 & 4

Students will observe, classify and test the physical properties and uses of materials. They will participate in processing some simple materials into a new product, and develop an understanding of material waste and pollution.


  • 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


  • Natural and processed materials have a range of physical properties; these properties can influence their use (VCSSU060)
  • 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)
  • 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 activities were engaging and interactive. The presenter was able to inform students about natural and processed materials in a fun way.” St Leo the Great

“Alex was excellent, she engaged with the students, facilitated wonderful discussions, and encouraged their love of science.” Korowa Anglican Girls
