Water Purification ● Campus Beautification

Our project is about rebuild the fish pond in the garden. We know water makes up almost 71 percent of earth’s surface; water also covers the planet to an incredible depth. Water is so important. Water are sufficient, water supply is a vitally important issue. Vast quantities of water are wasted in daily activities, and in some parts of the world supplies are getting dangerously now. We know about 2.5 percent of earth’s water consists of freshwater, rest of the water are salt water. In one sense, water can be seen as a renewable resource because it is constantly replenished as part of the global water cycle. However, the reality is a little bit complex, because not all water by human or other organism is instantly replaced and used.
          We want to rebuild the fish pond in the school, we can learn about how importance water is, also we can learn more about our ecosystem. See in what environment fish could be survived and what kind of water can let them survive.  We also can learn more about how to recycle the dirty water in the pond.
