In 4 Willow, we have been studying sound in Science. In our experiment we used cling film, a tea towel, bubble wrap, tin foil and a newspaper. We made the test fair by making everything the size of the tea towel, wrapping them all in the I pad with a timer that sounded a bell after fifteen seconds. Our results showed that bubble wrap was 1st, absorbing most of the sound with foil absorbing hardly any.

We used ear defenders to see how much they absorbed the sound around us.
