Good, good, good, good vibrations June 2015 Yr 4

Year 4 have been getting to grips with the quite difficult concept of sound being vibration.  This latest investigation tested how sound/vibration travelled along different types of 'string'.  Different thicknesses of actual string were used, as also some other materials like wool, embroidery cotton and silk and even some metallic thread.  Try it yourself to find out what the children were experiencing.
