Tryfan and Yr Wyddfa visited Ysgol Bryn Alyn yesterday to take part in a science and engineering workshop, as part of transition to secondary school. The children worked together as a team in groups of 3 or 4 to create a catapult using lollipops and elastic bands. The aim was to use the catapult to knock down some zombies. Well done to all, who made some fantastic catapults and well done to Joshua who managednto know down a zombie! We had lots of fun.
