Output

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.
