This week, we have been making Roman weapons in the form of trebuchets and catapults. We researched these weapons and decided which were the best materials to use to re-create one. We then designed our own catapults using the specifications in our ‘design brief’.  Constructing strong, sturdy shapes was a fiddly task but after some quality control, evaluating strengths and adjusting them where needed, we had made some fabulous catapults! We tested them outdoors and measured how far we could lauch a ‘boulder’. We then shared our learning with year 4, who were very impressed! Finally, we had a ‘shoot out’ in battle line formation to see which class was the winner!
