experiments
  • 1 - What is sound?

    experiment "What is sound?"

    The students examine the sound - the basic question "What is sound?" is answered by a spring steel strip and a steel needle.


  • 2 - Can you see sound?

    experiment "Can you see sound?"

    In this experiment, a tuning fork is struck and held in a bowl of water. The behavior of the water surface is observed.


  • 3 - Sound exerts pressure

    experiment "Sound exerts pressure"

    In this experiment, a ball is held by the thread to a tuning fork. This is struck and the students observe the behavior of the ball.


  • 4 - How can sound be amplified?

    experiment "How can sound be amplified?"

    In this experiment it is observed when a sound can be amplified.


  • 5 - How can sound be transmitted?

    experiment "How can sound be transmitted?"

    The volume of the sound is compared through a hearing tube and an ear piece.


  • 6 - High and low tones

    experiment "High and low tones"

    The students use high and low tones to investigate when a tone-producing body vibrates faster or slower.


  • 7 - Sounding air

    experiment "Sounding air"

    The students use test tubes to check whether sounds can be heard.


  • 8 - Sound combinations / music

    experiment "Sound combinations / music"

    In this experiment, sound bars are stimulated to vibrate, which produce a tone and are transmitted through the air as sound.
