Build a beautiful home "son of Dayu" and walk into Shazitang Elementary School to carry out interactive environmental protection classrooms

(Correspondent Du Qiu Zhang Yuting) "Some crazy green plants on the surface of the water are actually agricultural pollution!" "Looking at colorless water is not necessarily pure water!" On the 32nd national energy conservation and rowing week, Changsha University of Technology University The volunteers of the Youth Volunteer Association of Dayu walked into Shazitang Primary School in Changsha City and took a different "water -saving water protection" environmental protection class for the students.

"At present, the amount of freshwater resources used by humans only accounts for 0.26 % of the total global water resources." Volunteers start with the current status of water resources, and vividly introduce what is urban pollution, industrial pollution and agricultural pollution, and their treatments for their treatments. The impact on the ecological environment. "So what are the actions of water -saving water and water in normal life?" Following on how to protect and save water resources in daily life, volunteers discussed with classmates and encouraged students to start from the environment around them. In the life of life, we will jointly protect the precious water sources.

In fun experiments, volunteers led the students to learn the first step of the sewage treatment plant -the process and principle of the physical filtration through sewage filtering experiments. "My test strips are red, and this glass of water is acidic." "Mine is green, neutral!" In the use of Shirui test strip to determine the pH value, the students directly and deeply felt the water in the hands -on experiment. Wonderful and scientific mysteries.

"I know through this lesson. It is not easy for us to drink pure water. I want to cherish water resources and be a small guard to protect the earth. I also have to learn like volunteer brothers and sisters and actively participate in the river channel In the operation of cleaning and more 'water -saving water and water protection, "a classmate shared.

Since 1993, the Youth Volunteer Association of Dayu has made full use of the second class time to preach, issue environmental protection manuals, and produce propaganda panels to be a propagandist and guardian of ecological environmental protection. They will lead more people to pay attention to the society and the times from a more scientific perspective, making green low -carbon and environmentally friendly civilization a habit, and make the concept of "water -saving water and water" deeply rooted in the hearts of the people.
