Last week, Y2 brought their favourite battery operated toys to school. We looked inside them to find out what sort of batteries the toys needed. Emma’s keyboard needed 6 AA batteries while Ben needed a cuboid-shaped 9V battery to operate his metal detector. We also looked at some flat circular batteries and some AAA batteries. The children found out that the batteries provided the power which went around a circuit inside the toys. This made the toys work in different ways. Some toys moved, some made sounds and some had lights! It was a very exciting science lesson, which was part of our Electricity science topic! Here are some photos to show you how we got on.
