Sound sensor

In this unit students explore how sound is produced, they use the sound sensor to record the sound of a tuning fork and to display its sound waveform. Activity I. What is sound
In this unit students learn that sounds need a medium to travel and can travel not only via air but also via other materials. Activity III. Making musical sounds
In this unit students use the sound sensor and measure the sound intensity of different sounds. The sound sensor works as a sound level meter and measures sound level in decibels (dB). Activity V. How loud?
In this unit students realise that sound can cause hearing damage and investigate ways of decreasing sound intensity. Activity VI. Stop that noise
