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

HOW TO PROCEED [PROCEDURE]

Physics science project - Acoustics
  1. To make some carbon dioxide 'gas', mix together two tablespoons of baking soda with some vinegar in a large pouring bottle. The vinegar will make the 'soda' fizz and in the process carbon dioxide gas is released.
  2. Now pull the opening of a balloon over the mouth of the bottle so that it fits tightly.
  3. Wait while the balloon becomes filled with carbon dioxide gas, produced by the baking soda and vinegar, and remove it from the bottle. Close the open end of the balloon.
