Order the Charge Story
Start with Atom. Next, focus on what is inside an atom (Proton and Neutron in the center, Electron around it). Then decide how charges interact (Attract and Repel). Finally, end with how charge build-up can cause a big event (Static Electricity → Lightning).
Reading
Everything begins with an atom. Inside the atom is a tiny center (the nucleus) where protons and neutrons stay together. Around that center, an electron can move. When charges get close, they do predictable things: opposite charges attract, and the same charges repel. If electrons build up in one place, the object can become charged — that’s static electricity. If the charge difference gets big enough, it can suddenly release as a bright discharge: lightning.
Tip: Use the reading to decide what happens earlier vs. later (tiny pieces first, big event last).
