Today in class, students constructed from 19 puzzle pieces their ideal river. This is their comments from today’s activity. We learned that if cows “poop” in a river, then it needs to be cleaned up before people do anything with the water. In Brazil, people don’t drink the tap water because it has germs in it. Recently, one student who has another home in Gloucester was also effected by dirty water. We discovered that the most common problem doing this was where to put the waste and water treatment plants. It felt like we were creating miniature worlds, and it seemed like it was impossible for everyone to have clean water. One town or city would have to have polluted water, but we managed to make it clean. There seemed like there was always a problem because we had to keep switching squares. It felt like to me that we were making man-made rivers, but we needed to make sure that when the river got to the ocean that it was clean so the sea creatures wouldn’t be killed off.
