                     In this activity, You will build a car window glass lifter using a motor and a
                     push button. When the push button is pressed, the motor will make the fan
                     spin, showing how a car window would move up or down.

                     Concepts

                        • Using a Motor to Lift: You will learn that the motor helps things move, like
                        how it could move the car window up and down. The motor gets power from
                        the battery.

                        • Push Button Control: The push button is like a switch. When the button is
                        pressed, it turns on the motor, and when the button is released, the motor

                        stops. This is how we can control when the window goes up or down.

                     Observations

                     In the Car Window Glass Lifter activity, You will observe:

                        • Pressing the button makes the motor spin, just like how a car window can go
                        up or down.

                        • When they release the button, the motor stops, just like how a car window
                        stays in place when you stop pressing the button.

                                                                            Understanding Circuits and Electronics  45
