Ever wonder what makes up all of the stuff around us? Just like the toys that every kid plays with to build things, atoms are the building blocks of life that combine to form animate and inanimate objects. Readers journey into a microscopic world that they may not have known was even there. A single atom itself is made of three different particles: protons, electrons, and neutrons. It's packed full of energy, spinning around, and constantly vibrating. Fascinating facts in accessible language explain the smallest bits of living things. Simple diagrams support the informative narrative.
