What are electrons moving through circuits?

Electrons are like tiny people walking through a hallway to do a job.

Imagine you're at a party and there's a long hallway full of people. At one end of the hallway, someone starts pushing the person in front of them, and that person pushes the next one, and so on, everyone moves forward because of that push. That’s kind of what happens with electrons in a circuit.

A circuit is like a path made of wires where electrons can walk. It's closed, meaning there's no gap, it's like a full hallway from one end to the other. When you turn on a light, you're giving the electrons a push (like someone starting to push in our hallway), and they all move together through the wires.

Electrons are tiny charged particles, and when there’s a difference in charge, like a battery, it creates a kind of "push" that makes them move. This moving of electrons is what we call electric current.

So, when you turn on your toy car or light up your bedroom, it's just electrons walking through their hallway to do the job!
