Weekend's Research

The past couple days we've been researching water filtration or purification, for our prototypes, in Andrews class. All though its not a reliable site it is good for the basics, so i went to Wikipedia to find out all the known ways of purification such as reverse osmosis and several others. My group and i decided to research all the different ways of purification this weekend so I've been researching the concept of evaporation and condensation. A website that gave me a little better of an understanding is; http://www.epa.gov/ogwdw/kids/pdfs/activity_grades_4-8_waterpurification.pdf. I still need to research further into different ways to perform this filtration system.
