    • Power Source: The battery gives power to the LED.

                         • Resistor: The resistor protects the LED from getting too much power.

                         • Jumper Wires: These help the power move from the battery to the
                         LED, making it light up.

                      Observation

                      After putting all the parts on the magnetic board and connecting them
                      with the USB cable and jumper wires, the LED lights up brightly. Students

                      will observe that if the jumper wires are not connected properly, the LED

                      will not glow. They will also notice that the LED light stays on as long as
                      the battery is connected, showing how power flows through each part to
                      make the light work.

                      Application

                      Night lights: These small lights use LEDs
                      to  gently  light  up  a  room  or  hallway  at
                      night. Just like in the activity.

                      Portable Fan Model

                      A portable fan model is a simple, small fan that you can carry around to
                      stay cool wherever you go.

                      It's a great way to understand how fans work and how electricity can

                      power machines.

                      Components of Portable Fan Model

                      Following are the components of portable fan model:

                         • Motor: A motor is a small machine that makes things move. When you
                                                         connect a battery, the motor spins, which can

                                                         make things like wheels or fans move.

                         •  Fan: A fan is a small thing that spins when connected to
                         a motor. It moves air and keeps things cool, just like a

                         bigger fan you might have at home.
