Plastics are (mostly) synthetic (man-made) materials, made of polymers, long molecules formed around chains of carbon atoms, usually filling in the spaces with hydrogen, oxygen, sulfur, and nitrogen. You can think of a polymer as a large molecule repeatedly called a monomer "Poly" means many, so "Polymer" is simply short for "many Monomers". If you wonder how a long coal train is made of several trucks together, it is like a polymer.
