Year 4 have been working hard in their science lessons this term. Over the past few weeks, we have been learning all about 'sound'. We have been asking ourselves, how is it created? How do our ears allow us to hear? We have been playing a variety of different instruments in order to investigate these questions. We created sound using drums, our voices, triangles and even rulers! The children discovered that the sound was created by vibrations and it travels in sound waves.
