Write what each word means, using the article.

Do not copy the article. Write two things you learned, the way you would explain them to a friend.

Answers below are taken from the article’s stored facts, so they match what the student read.

1. What is the feedstocks?Primarily naphtha from crude oil refining, and ethane/methane from natural gas
2. What is the primary petrochemicals produced?Ethylene, propylene, butadiene (olefins), and benzene, toluene, xylene (aromatics)
3. What are petrochemicals and where do they come from?Petrochemicals are made from fossil fuels like crude oil and natural gas. These fuels formed from ancient plants and plankton that were buried and heated deep underground for millions of years.
4. How do factories turn oil into the plastic toys we play with?Factories heat the oil in a process called steam cracking, which breaks the oil into smaller molecules. These small molecules are then joined together to create the plastic used in toys and many other products.

Feedstock: The raw material used in industrial processes to produce other chemicals or products.
Olefins: A class of unsaturated hydrocarbons, including ethylene and propylene, crucial for polymer production.
Aromatics: A class of hydrocarbons containing a benzene ring, used in solvents and the production of plastics and synthetic fibers.
Polymerization: A chemical process where small molecules (monomers) join together to form long chains (polymers), creating plastics.
