The boys and girls in Primary 4b have had an exciting first week back at school. The children worked together to build a catapult using wooden sticks. There was rich discussion across the groups about the process of designing and building the catapult. Each group were keen to ensure their catapult would be able to launch the objects the maximum distance. Once the catapults were ready, we took them outside and worked in groups to launch a range of objects. Once the objects had been released from the catapults, the children used materials such as tape measures and metre sticks to measure the distance the object has travelled. Back in class it was interesting to identify which group had launched their object the furthest distance.
