Reactive Chemistry Incursion (Levels 5 & 6)

Theme: Science – Chemical Sciences
Level: 5 & 6

Students will investigate the properties and behaviour of chemicals/materials. They will explore reversible and irreversible changes that occur when chemicals are mixed.


  • Discuss prior knowledge of matter and chemicals.
  • Observe and discuss the physical properties of a variety of clear liquids.
  • Investigate reversible change using salt.
  • Measure temperature change in a variety of chemical reactions.
  • Investigate the formation of a gas during a chemical reaction.
  • Observe an explosive demonstration.
  • Use a chemical indicator to observe colour change created by different chemicals.
  • Predict and record observations.


Victorian Curriculum: Content Descriptions


  • Changes to materials can be reversible, including melting, freezing, evaporating, or irreversible, including burning and rusting (VCSSU077)
  • 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)


“Charlie was a very engaging, informative presenter. The students gained a lot of new learning and thoroughly enjoyed every aspect of the hands on experiments and the discussion with Charlie. Thanks so much.” St. Fidelis Primary School
