Sound Investigation - 10/12/19

We spent a few weeks enquiring about sound. We discussed what creates a sound, and why we can hear certain sounds. Through our enquiry we developed the knowledge that all sounds are a wave of vibrations that travel through a medium into our ears. As scientists we are not content with just knowing facts, so we worked on ways to prove our hypothesis. The children were given a drum and some rice and then told to prove that sounds are caused by vibrations.
