An apology to parents.....

....for the torture your ears are about to receive.

Today in Room 4 we made a chicken in a cup. This involves using a plastic cup, string and a skewer to create a noise machine that can get quite loud! Tomorrow we are investigating our own changes to the contraption to see what might change in the sound - for example, what happens if we make the string longer? What happens if we use a different size cup?

We learnt a couple of weeks ago that sound is made from vibrations. So what is vibrating in the cup and why on earth is it so loud! Check out some photos of the construction process and a video of the finished product being used!
