Post related to Clean that water up!,

We made a mini wetland to see how water is filtered in nature . We used 2 plastic coke bottles which we cut in half, stones, gravel, sand, grass, wood chips and leaf matter. We poured dirty water onto the filter . After this first attempt, we rearranged the order of the materials in the filter to make it more efficient . After pouring the dirty water through the filter a few times , the water become cleaner .
