ed 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 Ive 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 didnt 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 thats what it was called....
