A pencil leaves marks on paper because its tip is made of graphite, which is like a soft, black powder. When you press the pencil against the paper and move it across, tiny bits of graphite stick to the paper, that’s how your writing shows up! No electricity needed, just pressure and movement.
Examples
- A child draws a smiley face on a notebook using only a pencil, leaving no trace of ink or electricity behind.
- A student writes notes in class with a pencil, knowing they can erase mistakes easily without any special tools.
