Light & Sound

Students sort materials as transparent, translucent or opaque, feel vibrations with tuning forks, build a box guitar to explore pitch, and create shadows with a torch.

What students will do

Students test a range of materials against a torch to classify them as transparent, translucent or opaque, then create shadow shapes and explore how changing the torch position changes the shadow. Rainbow peepholes and a magnifying glass reveal that white light contains colours and can be bent and magnified. Working in pairs, students touch a vibrating tuning fork to a ping-pong ball and water dish to see vibration made visible, then make a box guitar by stretching rubber bands across a box, adjusting tightness to change pitch. Students then use a single cup with a string threaded through a hole in its base as their own sound-maker, plucking and pulling the string to make different sounds, and a wave spring teacher demonstration closes the session.

Learning outcomes

  • Classify materials as transparent, translucent or opaque by testing them against a torch
  • Investigate how light travels in straight lines to form shadows, and how changing the light source's position and distance changes the shadow
  • Observe that white light can be separated into colours using a rainbow peephole
  • Investigate that sound is produced by vibrating materials and that vibrations can be seen, heard and felt using a tuning fork
  • Explore how changing the tightness of a vibrating material affects the pitch and volume of the sound it produces
  • Make and use a simple cup-and-string sound-maker and describe how pulling and plucking the string produces different sounds

  • VC2S6U08Enrichment

    Light from a source travels in straight lines, forms shadows, and can be absorbed, transmitted, reflected or refracted. View on VCAA ↗
