    turning things on. When the switch is OFF, it
                                                              opens the circuit and stops the flow, turning

                                                              things off, like a light switch in your house.

                        Resistor: A resistor is a small part that slows
                        down  the  flow  of  electricity.  It  protects

                        other  components  from  getting  too  much
                        electricity. For example, resistors are used
                        to make sure that LEDs don’t get too much power, which could cause them to

                        burn out.

                        Battery: A battery is the power source for a circuit. It provides the electrical
                                                       energy needed to make things work, like toys, remotes,
                                                       or flashlights. Batteries have two sides: a positive (+)

                                                       and a negative (-), and they must be connected
                                                       correctly for electricity to flow.

                        2 Jumper Wire: A jumper wire is a wire used to connect different parts of a

                        circuit. It helps electricity travel from one
                        component  to  another,  like  a  bridge  that
                        connects two points. Jumper wires are often

                        used to build and test simple circuits.
