We researched different catapults that the Romans used and then looked at various different wood, keeping in mind our aim of making a catapult which would be able to launch a pom pom as far as possible. We then chose the wood and set to work designing our catapults. When we made the catapults, we carefully measured and sawed the wood and glued them together, carefully following our plan! Finally, we evaluated our catapult and measured how far they could launch a pom pom, thinking about what we could do differently next time. The furthest launched the pom pom over 3 metres!
