Science World Sound Activities
Sound is all about vibrations.
The source of a sound vibrates, bumping into nearby air molecules which in turn bump into their neighbours, and so forth. This results in a wave of vibrations travelling through the air to the eardrum, which in turn also vibrates. What the sound wave will sound like when it reaches the ear depends on a number of things such as the medium it travels through and the strength of the initial vibration.
In the following 15 activities, students will use simple materials to create, visualize and feel sound waves, investigate vibration and its role in producing sound, and make their own percussion instruments.
