This Content Descriptor from Year 2 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

explore different actions to make sounds and how to make a variety of sounds, and recognise that sound energy causes objects to vibrate

Elaborations

  • • building vocabulary for describing sound, such as loudness and pitch, and comparing sounds made by musical instruments
  • • exploring different ways to produce sound using familiar objects and actions such as striking, blowing, scraping, plucking and shaking
  • • exploring how traditional musical instruments used by First Nations Australians produce their characteristic sounds
  • • exploring how voices have a unique sound by playing games such as guess the speaker
  • • observing vibrations produced by a twanged ruler held on a desk and experimenting with different ways of holding or positioning the ruler to produce observably different vibrations and sounds
  • • investigating how sound energy makes things vibrate such as when speaking, using tuning forks or observing music speakers
  • • investigating which materials best muffle sound

  • • designing and making instruments that produce different sounds, such as drums, rain makers, thongophones or box guitars
  • • discussing situations in which they have heard echoes and exploring how humans with vision impairment and other animals such as dolphins and bats use echolocation to locate objects in their environments

Year 2 ASSCIY2
Year 2 Science Achievement Standard
By the end of Year 2 students identify celestial objects and describe patterns they observe in the sky. They demonstrate how different sounds can be produced and describe the effect of sound energy on objects. They identify ways to change materials without changing their material composition. They describe how people use science in their daily lives and how people use patterns to make scientific predictions. Students pose questions to explore observed patterns or relationships and make predictions based on experience. They suggest steps to be followed in an investigation and follow safe procedures to make and record observations. They use provided tables and organisers to sort and order data and represent patterns in data. With guidance, they compare their observations with those of others, identify whether their investigation was fair and identify further questions. They use everyday and scientific vocabulary to communicate observations, findings and ideas.
