View the types of new substances that were invented by chemists during the last century.
Things to think about

- 2.Observe the different kinds of technology that were being used over 100 years ago. The narrator makes the claim that the last 200 years were the most important in history. Listen for at least five points he makes to support his claim. What type of chemistry does he say is responsible for the greatest changes?

Organic chemistry has led to new products being made — those developed from crude oil and natural gas, for example. Think of ten things you use or rely on each day. Find out what they are made from or what they need to make them work. Chances are they have some connection to crude oil. Make a statement about the level to which your life is impacted by advances in chemistry.
