Think of it like this:

* Monomers are like the individual LEGO bricks.

* Polymers are like the complex structures you build with those LEGO bricks.

To make a polymer, many monomers join together in a long chain through a process called polymerization.

Here are some examples:

* Polyethylene is a polymer made from many repeating units of the monomer ethylene.

* Polyvinyl chloride (PVC) is made from the monomer vinyl chloride.

* Proteins are polymers made from chains of amino acid monomers.
