Physics

  • Make music with bottles filled with water

    When you tap a glass bottle with a spoon, it makes a sound at a particular pitch. It is vibrating or 'resonating' at that pitch which has a particular frequency, for example 300 beats per second. You can make...

  • Make music with a tin can and a string

    A tin can howler is a very popular toy with which one can have a lot of fun with! The same scientific principles are used to make this toy work, than is used to make many other musical instruments....

  • Use a balloon filled with carbon dioxide to amplify sound waves

    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...

  • Control the direction of soundwaves by reflecting it with umbrellas

    Sound waves can be reflected and when you are in a concert hall, you hear sounds bouncing from the walls and ceiling, often resulting in an enriched quality of sound. Test the reflection of sound with umbrellas in the...

  • Make a kazoo to learn more about sound & music

    Musical instruments make sounds by vibrating and then causing the air around it to vibrate. The specific sound that a musical instrument makes depends on how such an instrument vibrates the air around it. There are many ways to...

  • Make a tin can telephone

    When you speak, sound waves are created by vibrations or back and forth movements in the air. In other words, one can say that the air gets compressed and decompressed by these sound waves in the air.

  • Make a whistle to learn more about sound & music

    The specific sound that a musical instrument makes depends on how such an instrument vibrates the air around it. Make a whistle in the following science experiment to learn more about sounds.

  • Testing the best conductors of sound

    In this science experiment we will be testing common materials which is better conductors of sound, and will enable us to hear a watch tick more than a metre away.
