In science on Tuesday the 10 of October 2017 we made ear defenders using plastic cups and different materials. Our materials were cling film, foil, cotton wool and paper . The people in my group were me, Chiara, Tristan, Millie, Iggy and Ivo. What we had to do was take our material and place it around the inside and outside of the cup. And then we had to chose who was going to wear them, in the end we decided that Tristan was going to wear them. So what we had to do was we would take it in terns to shake the shaker but we had to be silent so the only noise was the shaker. What Tristan had to do was put the ear defenders on and wait for the noise and then he had a chart in front of him and it said each of the materials all he had to do was chose from a scale of 1 to 10. 10 meaning that you cant hear a thing a 1 meaning that you can hear everything. In the end we found out that cling film was the best and paper was the worst.
