1 Playing With Polymers Name Site #1: Polymer Basics Go to Mrs. Hellinga s Chemistry page. Click on the polymer power point to answer the next 4 questions. 1. What is polymerization? It is the process of chemically bonding to form. 2. What are some examples of natural polymers? Cotton, silk, wool, and natural rubber are all polymers made from plant or animal products. Protein is an essential ingredient in living matter and is made up of monomers called. It is also called a chain. The found in our cells is also a polymer. The monomer units of DNA are and the polymer is known as a polynucleotide. 3. What are some examples of synthetic (manmade) polymers? Some synthetic polymers are manmade and fabrics such as polyester,, and rayon. is a synthetic polymer used to make a variety of products, such as water bottles, plastic, and kitchen utensils as well as safety, computers, and rocket engines. Polymers are also used in as substitutes for human, such as bones and arteries. 4. What substances are used to make synthetic polymers? They are made from materials called, which are made from. Petroleum is made from the remains of and that have beneath sediments at the bottom of the ocean. Over time, and changed the remains into petroleum, which is a resource. Site #2: Hands-On

2 Plastics Click on kids zone. Go to Chemistry, matter and atoms, then hands on plastics. 1. Plastics are, which is something made of many similar to a chain. Each link in the chain is the or basic unit usually made out of,,, and/or. To make the chain, many links or units are hooked or together. 2. Many common classes of polymers are composed of, which contain the elements carbon and hydrogen. List seven elements that are also found in polymers:,,,,,, and. 3. What is one of the most famous silicon-based polymers? 4. What are the general attributes (properties) of polymers? A. Polymers can be very resistant to. B. Polymers can be both and insulators. C. Polymers are very light in with varying degrees of. D. Polymers can be in various ways to produce thin fibers or very intricate parts. 5. What percentage of our trash is made up of plastics? % 6.
