Molecular amateur for a 3rd grader.

Do you like to play with your Lego? Try Molecular Games - it's so much fun! This video is about third grader building different molecules. The molecular formula C2H4O may refer to: Acetaldehyde, Ethenol, Ethylene oxide From Wikipedia, the free encyclopedia Acetaldehyde, sometimes known as ethanal, is an organic chemical compound with the formula CH3CHO or MeCHO. It is a flammable liquid with a fruity smell. Acetaldehyde occurs naturally in ripe fruit, coffee, and fresh bread, and is produced by plants as part of their normal metabolism. It is popularly known as the chemical that causes hangovers. Ethenol, also called vinyl alcohol, hydroxyethene or hydroxyethylene, is an alcohol with chemical formula C2H3OH (H2C=CHOH) and CAS number 557-75-5. Under normal conditions, it tautomerizes to acetaldehyde. For this reason the thermoplastic polyvinyl alcohol (PVA or PVOH), which would be derived from this monomer, is made indirectly by polymerization of vinyl acetate followed by hydrolysis of the ester bonds. The chemical compound ethylene oxide is an important industrial chemical used as an intermediate in the production of ethylene glycol and other chemicals, and as a sterilant for foods and medical supplies. It is a colorless flammable gas or refrigerated liquid with a faintly sweet odor. It is the simplest example of an epoxide.

What to Eat by Marion Nestle - A Nutrition Book Review

!±8± What to Eat by Marion Nestle - A Nutrition Book Review

I stumbled upon the book What to Eat by Marion Nestle, when friend suggested that she wanted to buy it. From the reviews I have read, the book has some very powerful and practical guides connected to everyday eating that can save you from adding tons of useless fat and sugar in your system and to help you make healthy choices for your future and your children's future.

There is even a section on environmental degradation as related to food production. In relation there is a section on how environmental practices and fish production are causing major pollution of fish up the food chain. Knowing such information is very important to us, buying such foods leads to more and more pollution of the environment and eating heavy metals.

One of the strong points I noted is that, the author leads you through the supermarket aisle, in every section going through labels and the long chemical names used. You will be a more informed consumer and the best part is that you will avoid eating food coated with poison like substances.

For the most part there is always the confusion of the terms natural and organic and companies that sell packed food use the term natural to lure unsuspecting customers to buy their products. It is therefore wise to have a book that will walk one through the labels and make one a very informed customer.

The book is 600 pages long, with a clear advice to eat less, consume more vegetables and fruits and exercise to keep healthy. Although this has become a cliche it is worth noting. Having writers who come up with detailed information on the subject are more than welcome.

I am giving what to eat a five star because I am a mother and even though it may not work with everyone, it is important to breastfeed. The author shares some information pointing to the fact that formula milk is contaminated and poses a danger when give to premature babies.

What to eat is a perfect addition for nutrition and fitness books. It is written by a nutrition professor so you know they are the words of an expert. What to eat, is currently available for a very low price, cheaper than the amount you will use to order pizza and soda in as single meal.

The only downside with the book is the high number of pages. It is about 600 pages long. But considering that it has different sections it can be kept for reference to be used time and time again.
