INTRODUCTION [METHOD]

In a normal situation one will have difficulty hearing a watch tick more than half a metre away, because our ears are separated from the watch by air, which is not a very good conductor of sound. In this science experiment we will be looking which property of materials makes for better conduction of sound:

STUFF YOU NEED [MATERIALS]

  • BALLOON
  • SPOON
  • BOTTLE
  • VINEGAR
  • BAKING SODA
  • TICKING WATCH
