Year 4 have started their Science work on Sound this week and have been learning all about how sound is made and how it travels. They had an exciting afternoon today when they made string telephones to demonstrate how sound waves can travel from one object to another. This was a fantastic learning opportunity to find out about Alexander Graham Bell and to create a fair test to see if it was easier to hear someone with a tight or loose string or a short or long one. Great work Year 4.
