Good vibrations!

4S have started to learn all about sound in Science and so in this week's lesson, the children investigated different vibrations, as sound is a type of energy made by vibrations causing movements in air particles.The experiments included strumming and plucking ukuleles, 'dancing rice' on drums and seeing the effects of different sizes of tuning forks in water (a rather wet experience for some!). They identified how pitch and volume could be altered by the size of the vibrations and how vibrations accurately created sound by moving through the air as sound waves. Although it was a rather excitable (and loud) afternoon, lots of learning and fun took place, which was great!
