In the second part of our DT lesson, we added the circuits to the casing ( water bottles) and fixed these together securely, ensuring that the switch was still in working order. Throughout this unit the children have worked extremely hard to develop their subject knowledge about electrical systems including identifying electrical products and explaining why they are useful, making a working switch, identifying the features of a torch and creating and designing a functioning torch. Following the testing of each design, we will now move on to evaluating the success of a final product.
