Dirty water

Dirty water, as the name suggests, is very dirty water. But the students, you know the dirty water, how to become clean water? Let us go to class 5.3 today!

One day, we accidentally received a task, and we were going to filter dirty water on Friday. This message exploded in my mind, and the brain cells cheered.

Going home, I started looking for materials. Suddenly, my eyes lit up, "Oh, fine stone!" I held it like a treasure, and my eyes were bright. I thought: Ah, I finally found it, and I can sleep peacefully.

In the first class of the afternoon, we took the materials to the side of the billiard table and started the gorgeous transformation of dirty water. Zhu Yingjie and I used a ruler to cut charcoal, because I think the charcoal is broken and filtered. Yan Zhan and Liu Yating are carrying out the major secrets of our group - cutting the chalk. Cut the chalk to make the water white. Haha, my team leader is not bad! At first I just wanted the chalk to act as a fine sand, but when I saw other groups cutting the chalk, I had a "evil" in my heart.

In the process of our cut, Teacher Liang came to our team three times and five times and saw that our team was empty and began to worry about us. "Yeah, Teacher Liang, we have succeeded!" I looked for it with my voice. It turned out to be Qin Yu and their group. I felt a kind of crisis. The people in our whole group were nervous. The movements of all the members immediately accelerated. I said to the group staff with a sound of 100 decibels: "Everyone is going to speed up, and it must be better than the group of Qin. Yingjie, you don't want to cut it too much, it's a waste of time. You don't have to cut small charcoal. You can cut a small charcoal!" After the group, the people immediately stuffed the material into the bottle. I quickly took out the charcoal and small charcoal from the pencil case and hurriedly put it into the bottle. Then I took out the cotton from the things Liu Yating prepared and quickly stuffed it into the bottle. At this time, Liu Yating said to me: "Pour the chalk ash into it, we must do better than the Qin dynasty group!" I carefully poured the chalk ash into it, I looked at the information sheet, the next step is to put fine sand, "close to here. There is a place with fine sand, I will take it!" Zhu Yingjie volunteered to grab the fine sand. A minute later, Zhu Yingjie came back with a handful of sand. I hurriedly put the sand into the bottle. The next step is to put the leaves, Liu Yating put a handful of ginkgo leaves into the bottle. Finally, we put another layer of cotton, which is called Zhu Yingjie dumping dirty water. When the water came out of the bottle, my heart mentioned the eyes of the scorpion, but the black water was coming out. I was like a deflated ball - flat, I turned the black water helpless, when I When I gave up, I found that the water was getting clean. I was so happy that I jumped up and I was very excited.

! We must love the water! !
