                      In this activity, students will create a fan regulator circuit that allows them to
                      control the speed of a fan using a potentiometer (a special dial). When the fan
                      is turned on, adjusting the knob will change the fan’s speed, like how we modify

                      the speed of a ceiling fan in our homes.

                      Concepts

                          Electricity and Motion: Students will discover how the electricity from the
                         battery powers the motor, causing the fan to spin. This demonstrates that

                         electricity can create movement in objects, such as fans and toy cars.

                          Adjusting  Speed  with  a  Potentiometer:  The  potentiometer  is  a  special
                         knob that regulates how quickly or slowly the fan turns. By turning the knob,
                         students can control the amount of electricity flowing to the motor. More

                         electricity increases the fan’s speed, while less electricity decreases it.

                      Observations

                      During the Fan Regulator Circuit activity, students will notice:

                          The fan begins to spin once the circuit is connected.

                          Adjusting the potentiometer knob changes the fan’s speed.

                          The faster they turn the knob,
                         the  quicker  the  fan  spins;
                         turning  it  in  the  opposite

                         direction slows the fan down.

                      Home Appliances

                      The  most direct  application
                      is  in  household  fans  and  air

                      conditioning units, where speed
                      regulation is crucial for comfort.
                      Students  gain  insight  into  how

                      we  can  adjust  the  airflow  and
                      energy  consumption  in  our
                      homes.
