Science K–10 - Stage 3 Physical World


A student:

  • ST3-6PW

    describes how scientific understanding about the sources, transfer and transformation of electricity is related to making decisions about its use

  • ST3-7PW

    uses scientific knowledge about the transfer of light to solve problems that directly affect people’s lives


  • Electrical circuits provide a means of transferring and transforming electricity. (ACSSU097)
  • Students:
  • identify potential risks and demonstrate safe use when using electrical circuits and devices WE
  • demonstrate the need for a circuit to be complete to allow the transfer (flow) of electricity
  • construct simple circuits incorporating devices, eg switches and light globes
  • observe and describe how some devices transform (change) electricity to heat energy, light, sound or movement, eg hair dryers, light globes, bells and fans LCCT
  • Energy from a variety of sources can be used to generate electricity and this knowledge can inform personal and community-based decisions about using these sources sustainably. (ACSSU219)
  • Students:
  • research and present ideas about the different ways electricity can be generated, eg burning coal or natural gas; solar, hydroelectric, geothermal, wind and wave-generated electricity L
  • describe how scientific knowledge can be used to inform personal and community decisions about the use and conservation of sustainable sources of energy (ACSHE217, ACSHE220) SEPSCLCCT
  • Light from a source forms shadows and can be absorbed, reflected and refracted. (ACSSU080)
  • Students:
  • classify materials as transparent, opaque or translucent, based on whether light passes through them, is absorbed, reflected or scattered
  • observe and describe how the absorption of light by materials and objects forms shadows, eg building shading
  • gather evidence to support their predictions about how light travels and is reflected CCT
  • research, using secondary sources to gather information about science understandings, discoveries and/or inventions that depend on the reflection and refraction of light and how these are used to solve problems that directly affect people's lives, eg mirrors, magnifiers, spectacles and prisms (ACSHE083, ACSHE100) CCTICTL
