Year 4 spent the afternoon exploring how different materials work as a soundproof lining for blocking loud music - maybe useful for when they are teenagers for their bedrooms!!

The same cereal boxes were used but then lined with a range of different materials. Loud music (on my phone!) was sealed inside each, and the decibel level was observed on a data logger. 

Some children certainly made the right prediction!
