Water

Water is important in our lives because we use water all the time. We need to conserve water because most of the water in earth is slat water . About 90% is salt water , 6% is frozen water and about 3.4% is water we can drink . We cant drink salt water because we can die . Although we could filter the salt water it would cost more . It will cost more for the filters. For example we did an experiment in class we got really bad water with a lot of things in it . It smelled. So then we did are own filter we used :Sponge, charcoal, sand, coffee filter,cotton balls and more . The water looked better but it still was really dirty.So if we try to filter the water that is dirty in earth it would cost a lot . Mostly for the filter. We need to save water in earth. We couldn't live with out water . We also did a footprint to see how much water we use . It help us to know how we need to save our water in earth.
