The middle of a pencil is filled with something that we call lead. There is a metal called lead, but this is not what pencil lead is made of. Pencil lead is actually made from something called graphite.
So, why is it called lead when lead is not even used? In the 1400s, the Romans did write with the metal called lead. But in the late 1400s, a soft rock was found to be better. People began to write with this soft rock instead. This soft rock became known as graphite. Even though pencils no longer used lead, the name "pencil lead" just stuck.
