    • They will see how the motor works together with the battery and switch to
                         control the movement.

                      Application

                      You may have noticed that when we press a switch,

                      the fan turns on or off. The switch is controlling
                      the motor of the fan by either allowing or stopping
                      the  flow  of  electricity.  With  a  simple  press, you

                      complete or break the electrical circuit, which is
                      what powers the fan.
