Year 4 Science – switches

During our exploration and investigations of electricity we have learnt about direct current and static electricity, complete circuits, bulbs, motors, wires, conductors and insulators.
This week we have asked ourselves why we use switches, what kinds of switches we know of and use and what would happen if we didn’t have the use of switches.
The children then attempted to make their own switches. Creating circuits and using a buzzer the children had to creat a switch for a science quiz at the end of the day.
