Abstract
Plastics are made of polymers, chemical structures containing many repeated subunits. How does the polymer type of a plastic affect the biodegradability of the plastic? Do research on how plastic is made and what types of polymers are used for making different plastics. Can you learn to make your own plastic? What materials can you use for making plastic that is biodegradable? Test biodegradability by burying plastic samples for different lengths of time. (Kadar, 2004) Reducing solid waste and consumption of non-renewable resources are both worthy goals. Coming up with a biodegradable plastic gets you only part of the way there. In order to be a substitute for petroleum-based plastics, a biodegradable plastic needs additional material properties that available plastics have. For a more advanced project, consider these other properties, too. For example, would a biodegradable plastic be strong? Inexpensive? Would it last long enough to do its job?Share your story with Science Buddies!

Chemical Engineer
Chemical engineers solve the problems that affect our everyday lives by applying the principles of chemistry. If you enjoy working in a chemistry laboratory and are interested in developing useful products for people, then a career as a chemical engineer might be in your future. Read more
Materials Scientist and Engineer
What makes it possible to create high-technology objects like computers and sports gear? It's the materials inside those products. Materials scientists and engineers develop materials, like metals, ceramics, polymers, and composites, that other engineers need for their designs. Materials scientists and engineers think atomically (meaning they understand things at the nanoscale level), but they design microscopically (at the level of a microscope), and their materials are used macroscopically (at the level the eye can see). From heat shields in space, prosthetic limbs, semiconductors, and sunscreens to snowboards, race cars, hard drives, and baking dishes, materials scientists and engineers make the materials that make life better.
