Questions/Activities:
1. Post a picture of three 3-dimensional Ball and Stick molecular models (choose your three favorite molecules) that you have created with common items around your home. Also post a molecular structure image (image from the web, of either a Kekule Structure or a Ball and Stick Model) and the IUPAC name of the molecule.
2. Post an image from the web, the chemical systematic (IUPAC) name, common name, and the molecule formula for 20 chemicals that you use or eat. Explore the ingredients of things like cosmetics and foods.

3. Look over your molecules and the bonding characteristics, how many bonds does each of the following elements typically have? Carbon? Hydrogen? Oxygen?
Carbon 4 bonds
Hydrogen 1 bond
Oxygen 2 bonds
4. What does IUPAC stand for?
International Union of Pure and Applied Chemistry
5. As you explore ingredients, notice how everything around us is made up of chemicals consisting of atoms bound together into molecules. But what about companies that claim their products are chemical free! How can this be? Here is an example:
I feel that everything has chemicals in products even if they do say “chemical free”. I think that companies should say more things such as no bad chemicals are in their products.
