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.

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

Magnesium Hydroxide, Milk, Mg(0H)2
Ammonium Chloride, Shampoo, NH4Cl
Sodium Chloride, Salt, NaCl
Water
Oxidane, Water, H20
Sucrose, Sugar, C12H22O11
Sodium Fluoride, Toothpaste, NaF
Sodium
Hypochlorite, Bleach, NaClO
Aluminum Chloride, Deodorant, AlCl3
Dextrose, glucose, corn syrup, C6H12O6
Hydrogen peroxide, Peroxide, H2O2
2-propanol, rubbing alcohol, CH3CHOHCH3
Sodium tetraborate decahydrate, Borax, Na2B4O710H2O

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.
Keep in mind, that everything at the molecular level is a chemical, whether it
be made in nature or in a lab.
Everything around us is made up of chemicals-nothing is chemical free. The Green Aussie Cleaner, however, uses non-toxic chemicals, or natural chemicals that come from ingredients such as raw vegetable materials with corn supplying the carbohydrate/sugar base. They then combine native oils that produce alkyl polyglyoxide.
Nice job with your 3d models! They are very easy to read and done very "crisp". I like that you included the actual picture of the 20 items, its fun to look at the formula and then look at the picture; it's amazing that the formula can stand for something that we use almost everyday! Your explanation for #5 is very good, makes a lot of sense. I actually answered mine a little differently but your answer puts it in a whole new perspective for me. Nicely done!
ReplyDeleteI really learned a lot from the "20 Things" activity. I never realized how many things actually have a molecule formula. I know that sounds a little dumb but its true! I have never really thought our a product or an item having an actual formula. For example, pepper and the cream of tartar, I never really thought of them as a "chemical" thing, I just always viewed them as a sort of spice. Great job!
ReplyDeleteI really enjoy your layout of your 3d models. With your 20 Things activity I felt you brought such a different perspective to molecule formulas. Like Collen said the different products you used were fun to look at and learn about!
ReplyDeleteThe biggest thing I took away from this posting was the bonding characteristics in #4. I had never really thought about different molecules having different numbers of bonds, but by looking at your models I can see why it occurs that way. Great posting, love the pictures and it was very organized.
ReplyDeleteThe materials that you chose for your 3D models were very creative by the looks of the pictures it seemed like they held together pretty well. In the last question how you brought up the point that chemicals can be in nature and in a lab as well is a great point when thinking about all the different types of chemicals out there.
