Water Filter Experiments

In Room 5 we did a science experiment. We made water filters. Hannah and I were buddies. There were 4 items. Cotton balls, sand, paper towels and bark. We had to put dirty water into our filters and watch it go through to the other cup. Me and Hannah picked cotton balls and paper towels. You had to try to make it clean. Whoever got the cleanest water wins five dojo points. Our one was one of the best but we just missed out of winning. Here is our filter.
