How Are Sounds Made?

Year 4 are currently learning about sound in Science. One of the questions children wanted know was ' How are sounds made?' We carried out a variety of investigations involving rice, drums, tuning forks, tin cans and even coat hangers! By carrying out the investigations we found that sounds are created through vibrations sending waves of energy to our ears.

'I really liked our investigation because the coat hangers made a high pitch sound on the table and a low pitch sound on the chair.' Natasha Salter4AC

'I thought it was great! I hit the tuning fork really hard which made a big vibration making the water spit like a firework.' Thomas Dymond-Buller 4AC
