2. Matter surrounds us in the form of solids, liquids, and gases.

3. 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!

4. Vitamin C 20 atoms: 6 carbon 8 hydrogen 6 oxygen C6H8O6C6H8O6 C6H8O6C6H8O6 Something Else Changing which atom is bonded to which can change the properties of a molecule. It will change how it looks and acts.

5. What is a polymer? Polymers are made of many many molecules Polymers are made of many many molecules all strung together to form really long chains. all strung together to form really long chains.  Polymers can occur in nature or they can be man-made. This is a small molecule. It is not a polymer. This is a polymer. Many molecules are strung together.

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

7. What kind of math is here? Long chains mean adding the same thing over and over. Long chains mean adding the same thing over and over. How does that relate to math? How does that relate to math? Long chains can be hard to analyze. Sometimes it’s easier to look at the parts. Long chains can be hard to analyze. Sometimes it’s easier to look at the parts. How does that relate to math?
