  Interactions between organisms can be described in terms of food chains and food webs and can be affected by human activity

  Elaborations

  • constructing and interpreting food chains and food webs to show relationships between organisms in an environment
  • recognising the role of microorganisms within food chains and food webs

  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

• Science: Levels 7 and 8 achievement standards

  By the end of Level 8, students explain how evidence has led to an improved understanding of a scientific idea. They discuss how science knowledge can be applied to generate solutions to contemporary problems and explain how these solutions may impact on society. They investigate different forms...

• VCSSU089

  Scientific knowledge and understanding of the world changes as new evidence becomes available; science knowledge can develop through collaboration and connecting ideas across the disciplines and practice of science

  Elaborations

  • investigating how advances in telescopes and space probes have provided new evidence about space
  • investigating how the development of microscopes has changed understanding of cell function and malfunction, and how this has led to improved medical treatments for disease
  • investigating how knowledge of the location and extraction of mineral resources relies on expertise from across the disciplines of science
  • considering how advances in technology, combined with scientific understanding of the functioning of body systems, has enabled organ repair and replacement
  • investigating how land management practices of Aboriginal and Torres Strait Islander peoples can help inform sustainable management of the environment

• VCSSU104

  Energy appears in different forms including movement (kinetic energy), heat, light, chemical energy and potential energy; devices can change energy from one form to another

  Elaborations

  • recognising that kinetic energy is the energy possessed by moving bodies
  • recognising that potential energy is stored energy, for example, gravitational, chemical and elastic energy
  • using flow diagrams to illustrate changes between different forms of energy
  • investigating the energy transformations in devices, for example, a catapult or a water wheel

• VCSSU105

  Light can form images using the reflective feature of curved mirrors and the refractive feature of lenses, and can disperse to produce a spectrum which is part of a larger spectrum of radiation

  Elaborations

  • exploring how images can change when the arrangement of the mirror or lens system is altered
  • exploring the mechanism of the human eye and corrective technologies
  • observing the spread and order of colours in the visible spectrum
  • describing the different types of radiation in the larger spectrum of radiation

• VCSSU106

  The properties of sound can be explained by a wave model

  Elaborations

  • describing how sounds are produced by different musical instruments
  • measuring the speed of sound
  • using a wave model to describe the measured properties of sound, wavelength and frequency

• VCSSU098

  Chemical change involves substances reacting to form new substances

  Elaborations

  • identifying the differences between chemical and physical changes
  • identifying evidence that a chemical change has taken place
  • investigating simple reactions, for example, combining elements to make a compound

• VCSSU097

  Differences between elements, compounds and mixtures can be described by using a particle model

  Elaborations

  • modelling the arrangement of particles in elements and compounds
  • recognising that elements and simple compounds can be represented by symbols and formulas
  • explaining why elements and compounds can be represented by chemical formulas while mixtures cannot

• VCSIS107

  Identify questions, problems and claims that can be investigated scientifically and make predictions based on scientific knowledge

  Elaborations

  • considering whether an investigation using available resources is possible when identifying questions or problems to investigate
  • using information and knowledge from their own investigations and secondary sources to predict the expected results from an investigation
  • recognising that the solution of some questions and problems may require consideration of social, cultural, economic or moral factors in addition to results from scientific investigation
