Noise Pollution and How to Reduce

This afternoon we created devices to help reduce noise pollution.  Noise pollution is any unwanted noise that cause stress.  We had lots of different ideas and used lots of different materials including bowls, water, ziplock bags, paper, ear plugs, jars and boxes.  We found out that sealing the noise in helped to reduce it.  Layering mediums also helped.  The thicker the medium the more the noise was reduced.  Lots of the devices we created worked really well.
