The purpose of this assignment was to learn about the process of the hydrological cycle and how it affects the human and animal life. My favorite part of the project was going to the zoo because we got to interview zookeepers. We collected all of the information needed and we were also able see the animals. I learned that the amount of water an animal needs depends on their weight and how big the area of their living space is. I also learned that the hydrological cycle can be changed using different materials in a project.
