Sommaire:This experiment tested which underground dam is better for stopping underground leaks of pollution, one made of clay or one made of frozen ground. These were compared in two ways: first, using bottles filled with different coarseness of ground materials; second, using aquariums with different underground dams. In this experiment, the clay dam worked better than the frozen dam.
