Year 4 have been learning all about Sound in our science topic this half term. We started by exploring the sounds around us by going on a sound walk. We had to be completely silent and write down all the different sounds we could hear in different rooms of the school. Then we made string telephones and learnt how sound waves travel through the air. We also explored pitch and volume, ear shape in animals and humans, and ended our topic by investigating the best material to muffle sound waves to create the most effective ear defenders. See the Sway below with some pictures:
