We just learned about Binary.

What's the smallest thing you can think of?
A grain of sand?
A drop of water?

Well even smaller than any of those is something called an atom.

An atom is so small, that in one single grain of sand there aren't just millions,
billions or trillions of atoms, but quadrillions or quintillions of them!

A quintillion is a 1 with 18 zeroes after it: 1,000,000,000,000,000,000

Atoms are the building blocks of our world, they make up every part of our bodies,
and every thing around us from the ground we stand on to the air we breathe.
