                     In the basic swing activity, when the battery is powered on, the DC motor spins

                     and moves the swing back and forth. The swing starts oscillating or stops when
                     the switch is turned on or off, demonstrating how electric circuits, motors, and
                     mechanical movement work together to create motion.

                     Concepts

                     Electric Circuits and Motors: You will explore how electric power from the
                     battery makes the DC motor run, which causes the swing to move. This teaches
                     the concept of how electrical energy is converted into mechanical motion.

                     Switch Control and Motion: The switch allows you to control when the swing

                     starts  or  stops by  completing  or  breaking the  circuit.  This  introduces  the
                     concept of simple circuits and how switches function in electronic devices.

                     Observations

                     In the basic swing activity, you will observe how the swing begins to oscillate

                     when the switch is turned on, allowing electricity to power the motor. You will
                     notice that the swing stops when the switch is turned off, as the circuit is broken
                     and the motor stops working. This activity provides a hands-on understanding

                     of how electric motors work, how energy is transferred, and how switches can
                     control devices.

                                                                               Building and Moving Simple Robots  29
