Over half term I am challenging the children to create their own catapult that can be used to compete against other catapults in class as part of our science unit on forces and our invaders and settlers unit in History. The design can be as simple or as complicated as the individual wishes. Ideally the children will be able to explain to onlookers how it works applying their new found science knowledge. If possible could the children bring in their completed designs the first Thursday back after half term to enable the invaders the opportunity to test their model out against their rival tribes. Thanks in advance.
