TRANSCRIPT
Plastic Spaceships and Plastic Bags1. What are polymers, and why are they generally viewed as useful
compounds?
2. Why is polyethylene considered a better material than Aluminum for constructing spaceships?
3. What are some of the obstacles and/or drawbacks to using polyethylene in spaceships?
4. What are “secondaries”? How does the formation of secondaries differ between aluminum (and other metals) and polyethylene?
5. What types of products are made from recycled #1 plastics?
6. Do you have any interesting facts about plastic recycling to share with the class?
