Polymers are made up of many tiny molecules strung together to form long chains (and sometimes more complicated structures).
Natural polymers are found in many forms such as horns of animals, tortoise shell, shellac (from the lac beetle), rosin (from pine trees), rubber (obtained from several types of trees), asphalt, and tar from distillation of organic materials.
Synthetic polymers are man-made polymers or plastics such as polystyrene, polyethylene, and PVC (to name a very few).
