We explored how sound is made my vibrations. We used a tuning fork to see, hear and feel vibrations after hitting the fork on the table. The children also enjoyed hitting a fork on a table and placing string by their ear to hear the sound - showing that vibrations move up the string. Similarly, the children placed string by their ear attached to a coat hanger which was also hit with a tuning fork. We also placed a vibrating tuning fork in water to see the water move and splash out. All of this was done to show vibrations create sound.
