* You: Your body is made up of billions upon billions of atoms, forming the complex structures of cells, tissues, and organs.

* The air you breathe: Oxygen, nitrogen, and other gases are made of atoms.

* The water you drink: Water molecules are made of hydrogen and oxygen atoms.

* The food you eat: Everything from fruits and vegetables to meat and bread is composed of atoms.

* The ground you walk on: Rocks, soil, and minerals are all made of atoms.

* The stars in the sky: Stars are giant balls of plasma, which are still made up of atoms (though in a very different state than on Earth).

* The chair you're sitting on: Wood, metal, plastic, and fabric are all made of atoms.

In short, anything that has mass and takes up space is made up of atoms.
