Circuits can make things spin and beep.

Each part of a circuit is a component. Bulbs make light. Other components do other jobs.
You can build circuits with bulbs, buzzers and motors in the Circuit Builder lab.
A motor spins when it is in a circuit. Motors turn fans, toy cars and washing machines. Easy-bikes and auto-rickshaws have big motors.
When electricity flows through the coils, the middle of the motor spins.
A buzzer makes a sound. Doorbells, alarm clocks and microwave ovens have buzzers.
A buzzer or bell turns electricity into sound.
A bulb changes electricity into light. A buzzer changes it into sound. A motor changes it into movement.
The button is a switch. Let go and the sound stops.
