At Lockers we enjoy a competition – in the main Prep School boys are very competitive! When Mr M Phillips set the Year 7 boys the challenge of making a trebuchet in technology, this just screamed competition! What, you may ask, is a trebuchet? Well in the days before gunpowder and cannon were in regular use, if you wanted to knock down the walls of a town you were besieging you had to knock them down with large boulders that you launched at them using a trebuchet. Of course the ones the Year 7’s made were not large enough to launch boulders, in fact stones were off limits, but they did manage to fling ping pong balls an impressive distance.
