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
I don't really think that any product, especially a cleaning product can be chemical free.  At the very least, there has to be water in the product. I think that people are trying very hard to be clean and 'green' and that makes companies feel that it is necessary to exploit the idea that their product either has less chemicals or maybe less potentially harmful chemicals. However, I find that it is a far stretch of the truth to call anything, especially a cleaning product, chemical free.
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.
