All children were provided with a bottle (cut in two) and a piece of kitchen roll (as a final filter). They had to work individually or in small groups to locate natural resources on the school field, which they felt would clean the extremely muddy water! Throughout the experiment, we discovered that the larger materials should be at the top and smaller materials lower down to make the water come out clearer! We also discovered that using nettles lead to the cleanest water... We wonder if you try this at home, would you get the same results? ### Water Filter
