Electricity is everywhere in our lives. It lights up our homes, powers our toys, keeps our cars running, and charges our favorite devices.

But what is electricity? Where does it come from? How does it work?

To understand this, let's first start by understanding matter. Everything around you is made of matter. Your shoes, your classroom, even you are made up of matter. If you go deeper, you discover that matter is made up of atoms. And atoms are made of a smaller, equal number of particles called protons, neutrons, and electrons.

The miracle of electricity happens when an imbalance, a different number of protons and electrons, occurs. Negatively charged electrons can be made to move from one atom to another. When those electrons move between atoms and attach a positively charged protons a current of electricity is created. The electrons move from one atom to another in a flow. Imagine this flow in a cord or a wire. The electricity moves from one end to the other, and you end up with the energy that powers all sorts of things.

Even though electricity is just one of the many forms of energy, it's also one of the most important because it makes modern life possible.
