As part of our science project, Gangsta Granny, the children designed, built and painted the Tower of London, to protect the crown jewels. They were taught how to make complete circuits to build burglar alarms, pressure pads and security systems. The children also learned about conductors and insulators and used tin foil in the circuits to make a break. Listen carefully to their explanations of how to create circuits – superb work. Really well done everyone.
