• VCSSU060

  Natural and processed materials have a range of physical properties; these properties can influence their use

  Elaborations

  • describing a range of common materials, such as metals or plastics, and their uses
  • investigating a particular property across a range of materials
  • selecting materials for a specified use based on their properties

• VCSSU073

  Scientific understandings, discoveries and inventions are used to inform personal and community decisions and to solve problems that directly affect people’s lives

  Elaborations

  • exploring objects and devices that include parts that involve the reflection, absorption or refraction of light, for example, mirrors, sunglasses and prisms
  • considering how electricity and electrical appliances have changed the way some people live
  • considering how decisions are made to grow particular plants and crops depending on environmental conditions
  • considering how guidelines help to ensure the safe use of electrical devices
  • comparing the benefits of using solid, liquid or gaseous fuels to heat a home
  • designing shelters for living things that are exposed to changed or harsh environments, for example, as a result of bushfire or displacement

  VCSSU073 | Science | Levels 5 and 6 | Science Understanding | Science as a human endeavour

• VCSSU095

  Mixtures, including solutions, contain a combination of pure substances that can be separated using a range of techniques

  Elaborations

  • recognising the differences between pure substances and mixtures and identifying examples of each
  • identifying the solvent and solute in solutions
  • investigating and using a range of physical separation techniques such as filtration, decantation, evaporation, crystallisation, chromatography and distillation
  • exploring and comparing separation methods used in the home

• VCSSU132

  Energy flow in Earth’s atmosphere can be explained by the processes of heat transfer

  Elaborations

  • recognising that the Law of Conservation of Energy explains that total energy is maintained in energy transfers and transformations
  • recognising that in energy transfers and transformations, a number of steps can occur and the system is not 100% efficient so that usable energy is reduced
  • comparing energy changes in physical events, for example, car crashes, the motion of pendulums, lifting and dropping

• VCSSU099

  Predictable phenomena on Earth, including seasons and eclipses, are caused by the relative positions of the Sun, Earth and the Moon

  Elaborations

  • comparing times for the rotation of Earth, Sun and Moon, and comparing the times for the orbits of Earth and the Moon
  • modelling the relative movements of the Earth, Sun and Moon and how natural phenomena such as solar and lunar eclipses and phases of the Moon occur
  • explaining why different regions of Earth experience different seasonal conditions

  VCSSU099 | Science | Levels 7 and 8 | Science Understanding | Earth and space sciences

• VCSSU103

  Change to an object’s motion is caused by unbalanced forces acting on the object; Earth’s gravity pulls objects towards the centre of Earth

  Elaborations

  • investigating the effects of applying different forces to familiar objects
  • investigating common situations where forces are balanced and unbalanced, for example, stationary and falling objects
  • investigating a simple machine such as a lever or a pulley system
  • exploring how gravity affects objects on the surface of Earth
