Science in Year 4

27 Apr 2015

We are learning about Sound in science this half term. We are learning that sound is created by sound waves moving through the air or objects and reaching our ear drum. 
We proved vibration with a few experiments this afternoon.



 

 We could see the rice jumping as we hit the drum skin.



 

 We hit each bottle to hear the different pitch. 


 

 Salas experimented with a tuning fork. Could we see the water vibrate when he put it on the water?


 

 Yes! Some times it even splashed us!



 

 Can you feel Ruth talking Elias?



 

 Do the sound waves created by Michael make the balloon vibrate?



 

 Every school child's favourite!
