Where
do chemicals come from? They're made in a chemical plant like the one
I'm visiting right now.
Chemists, engineers, and other people who work in this plant know how to safely store and handle the different kinds of chemicals used to make plastics and other products.
The chemical products are loaded into railroad cars like this, and then
shipped to factories where they are used to make all the different things
you buy in stores.
Besides railroad cars, can you name 3 other ways that chemicals might be shipped from a chemical plant to a factory?
