In the next room, we talked about pollution. First, we read a book about an amazing fish. Then, we talked about keeping our water clean by not throwing trash on the ground. We then took some paper and balled it up and covered it with foil. The balls of paper represented hills and the aluminum foil represented the grass. We drew our backyard and the items in our yards all over the grass with our markers. Next, the teachers poured "litter" all over our yards. Then, when the rain came down, we saw how the trash spread out everywhere and polluted our water and our ground.
