The video explores the concept of size, starting with visible small objects like grains of sand and bacteria, and then delves into atoms, the smallest pieces of matter. It explains that atoms are the building blocks of all matter and are too small to be seen. The video uses a piece of paper to illustrate the size of atoms and describes the structure of an atom, highlighting the nucleus and electrons.
