This Content Descriptor from Year 4 Science provides the specific knowledge and skills students should learn. Use it to plan lessons, create learning sequences, and design assessments that align with the Australian Curriculum v9.

Content Descriptor

identify how forces can be exerted by one object on another and investigate the effect of frictional, gravitational and magnetic forces on the motion of objects

Elaborations

  • • exploring the effect of magnets on other magnets and how magnetic forces can pull objects from a distance
  • • exploring the positive and negative effects of friction on their everyday experiences, such as how friction causes objects to slow down and stop
  • • recognising that gravity is the force that pulls all objects to towards the centre of Earth and that gravitational force acts on an object regardless of whether it is moving or not moving
  • • observing how the pushing force of a liquid enables an object to float
  • • investigating the effect of forces on the movement of objects in traditional First Nations Australians’ children’s instructive toys and games
  • • examining shoe sole design and identifying patterns in sole design and use related to friction
  • • watching a video of astronauts walking on the moon or dropping objects on its surface, and discussing the force they are observing

  • • exploring how force arrows can be used to represent the direction and magnitude of forces acting on an object

Year 4 ASSCIY4
Year 4 Science Achievement Standard
By the end of Year 4 students identify the roles of organisms in a habitat and construct food chains. They identify key processes in the water cycle and describe how water cycles through the environment. They identify forces acting on objects and describe their effect. They relate the uses of materials to their properties. They explain the role of data in science inquiry. They identify solutions based on scientific explanations and describe the needs these meet. Students pose questions to identify patterns and relationships and make predictions based on observations. They plan investigations using planning scaffolds, identify key elements of fair tests and describe how they conduct investigations safely. They use simple procedures to make accurate formal measurements. They construct representations to organise data and information and identify patterns and relationships. They compare their findings with those of others, assess the fairness of their investigation, identify further questions for investigation and draw conclusions. They communicate ideas and findings for an identified audience and purpose, including using scientific vocabulary when appropriate.
