Matter surrounds us in the form ofsolids, liquids, and gases.
Atoms, Elements, and Molecules
ATOMS-the basic building blocks of everything you see around you, even things you don’t see!
ELEMENTS-the kinds of atoms we can have!
MOLECULES-when atoms join together, forming bonds!

Changing which atom is bonded to which canchange the properties of a molecule.
It will change how itlooks and acts.

This is a small molecule. It is not a polymer.
This is apolymer.Many moleculesare strung together.

These long polymer chains are These long polymer chains are formed by teeny tiny molecules formed by teeny tiny molecules called called monomersmonomers..
A single polymer molecule is made A single polymer molecule is made out of hundreds of thousands (or out of hundreds of thousands (or even millions!) of monomers!even millions!) of monomers!
