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.
ETHANOL
METHANE
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.
Graphite=pencils
Lithium is in batteries
phosphorus and sulfer-Matches
acetic acid is in foods like vinegar
copper-pennies and coins
oxygen
aluminum-cans
iron-foods like meat and vegetables
butanoic acid
ascorbic acid-vitamind C
carbon crystal-jewels and stones
calcium carbonate
magnesium sulfate
fructose-foods and drinks
polyethylene
hydrolyzed starch
cirtric acid-juices like orange juice
oxidane
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
Hydrogen: 1
Oxygen: 2
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:
http://www.naturalhealthcareproducts.com/Cleaning-Products.php
Do a little web searching and propose what chemicals are actually in this product.
There are products like Lysol and Clorox that use harsh chemicals like bleach and amonia to kill germs and bacteria, and companies like those are starting to come out with "chemical free" or "safe" products. using less-harsh chemicals in your products do make them safer to use around children or food, but there can never be a "chemical free" product. All cleaning products will have some sort of chemical in them to kill the germs, but it just might not be as harsh as bleach.
