It was vey loud and noisy – drums banging, bottle organs tapping and hooting, voice balloons buzzing, rulers twanging and tuning forks humming. Our ears were ringing by the end of the lesson, but we learnt a lot about how sound travels. ![](https://yarmprimaryschool.net/images/blog/417.jpg) [ Year 1’s Flying Machines](https://yarmprimaryschool.net/blog/2019-03-22-00-00-00-year-1-s-flying-machines) [History of Yarm ](https://yarmprimaryschool.net/blog/2019-03-26-00-00-00-history-of-yarm) ![Yarm Primary Academy](https://files.schudio.com/yarm-primary-school-2/images/logo/Yarm-Logo(1).png) ### Yarm Primary Academy Spitalfields Yarm STOCKTON-ON-TEES TS15 9HF 01642 782731 ### Social Media - [Instagram](https://www.instagram.com/yarmprimaryschool/) © Copyright 2026 Yarm Primary Academy School & Trust Websites by [ ![Schudio logo](https://yarmprimaryschool.net/img/logo/light.png) ](https://www.schudio.com/)
