CHEMISTRY IN EVERYDAY LIFE During laboratory technique 1 we learned how to separate insoluble liquids from solids by means of filtration, and how to separate a dissolved solid from a liquid by means of evaporation. I have often asked myself the importance of some of the required classes in my schedule and how they can relate to everyday life. I believe in the saying that if you don? t use it you will lose it, meaning that if the concepts I learn cannot be applied to something that I will remember on a daily basis then the possibilities of me not remembering them at all are greater. This is especially true if you? re not a science or medical major as I am not.
However in this class I am discovering that things we are learning can definitely be applied to processes that my mind uses daily and procedures that are performed daily and are as close to me as my own kitchen. In pondering the idea of filtration and evaporation I begin to think of the water that I drink on a daily basis. Without even being aware of the process I have been using filtration on a daily basis. I purchased a filter for my sink a number of years ago to improve the taste of my water and get rid of what I called the (bad things) that my body didn? t need. At the time I had no idea I was making a scientific decision and using a scientific method.
I had determined that the water in my house did not taste well and that the taste could be improved. Listening to others who had boasted about the success of filtered water I decided to test their hypothesis out for myself. I bought from the local hardware store a basic water filter system that could be attached to the faucet of your sink. Supposedly this water filter would remove the harmful substances from my water and improve the taste. I tested the hypothesis by first pouring myself a glass of unfiltered water and sitting it aside. I then attached my filter system and poured myself a glass of filtered water.
I tasted both and observed the differences in each taste. The hypothesis was now justified in my eyes, the filtered water tasted better. I offered my hypothesis to my husband and children and allowed them to make their own observations. We all agreed that the filtered water tested better.
The hypothesis had now become theory in my household. Now since this class I? ve been observing just how this filter system works. I have discovered that the residue that remains after filtering in some way affected the taste of my regular tap water. I have since learned that this residue consists of salt and other stuff that could definitely dramatically affect the test. Interestingly enough though, this filtration process didn?
t start with me. Scientist years ago began to filter water for health reasons. Elements that are deadly to our human bodies (such as chloride) are filtered out daily through our elaborate water system to ensure that our water is healthy to drink. Without this process we would have entire cities dying just like the colony of Jamestown centuries ago!
Wow I guess science is a necessary in my daily life, I just never knew that? s what it was called.
