Water-the source of life, we all need water. It not only breeds life, but also benefits nature. Therefore, saving water is not only a virtue, but also a noble behavior.
Water is the source of our life. According to statistics, the average water content of human body is 62%, the water content of fetus is 90%, the water content of infants is over 80%, the water content of adults is 60-70%, and the water content of the elderly is less than 60%. Modern medicine has proved that "human aging is the process of cell drying", which shows the importance of water to people. In addition, our school also held water-saving activities.
On Friday, Director Chen asked the students to make a small card by themselves, and the students in our class gave it to passers-by at the end of the third class. This not only improves our awareness of water conservation, but also improves our personal cultivation.
World Water Saving Day-March 22nd is to alleviate the contradiction between supply and demand of world water resources. According to the principles of water resources protection, development and management in Chapter 17 of UN Agenda 265438+20th century, the 47th UN General Assembly adopted 193.
World Water Saving Day has raised our awareness of water resources protection. I don't know how many people lost their lives because of the water in the war zone But we, as long as we reach out, will have a lot of water, and we should feel lucky.
Water is the source of life. Cherish water, cherish water, save water, start from me, and don't let the last drop of water become our tears!
During the winter vacation, the teacher took us to the museum to visit the popular science exhibition "Water resources around us". I have benefited a lot.
Water is the most important and indispensable thing in our life, but now water resources are increasingly scarce. If we don't start saving water, the last drop of water in the world will be your tears.
If there is no water on the earth, plants can't survive, plants can't survive, animals can't survive, animals and plants can't survive, then can we humans survive? We either starve to death or die of thirst. At that time, we really only had a dead end! So we must save water from now on.
It's not enough to save water by just talking and not doing it. It's necessary to take practical actions.
My family does this: the water after washing rice is used to wash hands, then wash dishes and water flowers; People who wash their faces wash their feet and then flush the toilet; The washed water can be used to mop the floor or flush the toilet ... There are many ways to save money, and we need to think for ourselves. These are all the things I learned in the museum, so you can go to the museum more often when you have time, and you can learn a lot like me!
Collection of Fine Water-saving Compositions Nine Articles 3 "Wow ……" Little Water Drops are singing again! However, after a few days, I found the little water drop crying. I think: we must save water!
One day, I heard the sound of water rushing. It turns out that my mother is washing vegetables again. I rushed over and saw my mother preparing to pour out the water for washing vegetables. I quickly said loudly, "mom, don't pour it, the water is still useful!" " "My mother looked at me and put down the bucket and asked," Honey, these washed dishes are all dirty. What's the use? I said, "There are many functions, such as flushing toilets, watering flowers, washing mops and drinking water for dogs." ..... "Mom listened and boasted again and again:" Baby, you are such a water-saving expert! "
I think the little flower on the balcony is dying. I picked up the water ladle to water the flowers, and the flowers were very happy after drinking enough water. I saw the puppy staring at me blankly, so I quickly filled its basin with water. I am very happy to see it drinking water happily.
Suddenly, I found my face wet with small drops of water. Mother helped me dry the water on my face with warm big hands, and said happily, "My baby is great, and I know some tricks to save water!" " "At this moment, I seem to hear the water drops singing happily again!
Standing on the dam and looking at the reservoir, the water in front of us seems inexhaustible. However, through the teacher's explanation, we understand an amazing fact-water is the source of all life, and potable fresh water accounts for only 2.5% of the world's water! We can't help looking at each other, but we still hold the water bottle in our hands. You know how much I waste water. I used to throw garbage into the river! Thought of here, I feel even more ashamed, and my mood can't be calm for a long time. What can we do? What we can do now is to take good care of it!
In the afternoon, we played a "treasure hunt" game on a meadow downstream of Jiaokou Reservoir. Here, trees sprout and the grass is lush. At first glance, Koizumi flows quietly under the grass, and everything is so perfect and natural. But people littering is a discordant note. The game is to let us collect these rubbish. When the teacher gives the order, we are like nesting birds, scrambling to collect every piece of garbage. ...
I really don't know, but I was shocked when I read in the newspaper that China's water resources are particularly poor, and the per capita water resources only account for a quarter of the world's per capita water resources. I also said that the 2 1 century war may be a war for water resources, and I couldn't help but feel shocked: water is so important, why don't I care at all?
One day, after I went to the toilet, I turned on the water switch, and the water rushed from the water tank into the toilet bowl. The filth in the toilet bowl disappeared immediately, but the water that rushed in did not stop immediately. At this moment: I just stood and thought: if the water is stopped as soon as the dirty things are washed, wouldn't it save water? But is there any way to do this? I can't remember for a long time. Suddenly, I caught a glimpse of two wall bricks beside me, and I couldn't help thinking: why not try with bricks? I picked up a brick, lifted the lid of the water tank and put the brick in. Won't that reduce the amount of water flowing into the water tank? But I don't know if this is feasible.
In order to study this problem, I observed it. After my parents went to the toilet, I ran in and saw that all the dirty things in the toilet bowl were gone. I am happier than being a fairy, and I can't wait to tell my parents about it. When my parents opened the lid of the water tank, they were very happy and said I was a clever little girl. I smiled shyly and thought of another way to save water, so I said to them, "Mom, Dad, our whole family is taking a bath now, and everyone needs almost five buckets of water at a time!" " I have an idea. Let's squat and take a bath in the future, because everyone can save four buckets of water at a time. "My sister and mother said in unison," Good idea! "Dad was worried that he was not used to it, but because he was outnumbered, he could only say," All right. "Since then, our whole family has attached great importance to saving water: everyone will not fill a basin of water when washing their faces. My mother watered the flowers with washed water, and my sister got rid of the bad habit of not turning off the tap. My dad never dares to scoop the whole bucket to wash his feet when he comes back from work every day!
Students, don't underestimate this little water. Imagine: every time you go to the toilet, you can save a brick of water. If you go to the toilet three times a day, how much money can my family of five save every day? Changing bubble bath to squat bath can save four barrels of water per person every day. How much money can the whole family save? ..... If everyone does this, the water saved by the national population of1300 million will be enough for the world not to have a water war! Do you think so?
Dad obviously knows these truths better. No, he "sells" my "patent" everywhere, which leads me to be praised everywhere. Some people praised me for saving his family a lot of water bills, while others praised my mind. Xu teacher also gave me a piece of cardboard, which read "Water Saving Model" ... Oh, I'm so ashamed!
However, I am still willing to be a "small model of water saving", and I want to study more scientific water saving methods!
Students, do you know how much water our earth occupies? To tell you the truth, the water on the earth accounts for 97.3% of the total water. Some people may think that our earth is not short of water at all, but only 2.7% of the 97.3% water is drinkable, and a lot of water in this 2.7% fresh water is polluted, so we can only use about 0.3%.
If we compare fresh water to an apple, then the water we can drink directly accounts for only one sixteenth of that of the apple, that is, a small apple peel.
You may not believe that Lucheng District is a serious water shortage area, because Lucheng District does not have our own reservoir. Where does the water we drink come from 20% of the water in Lucheng District comes from Zeya Reservoir, 10% from Oujiang River and 70% from remote Wencheng Shanxi Reservoir. After listening to this data, you may say, "It doesn't matter. Anyway, my family has money, and it is difficult to ask for water. " You are wrong. What matters is not money, but what we should do in the future.
Some people don't just pat when washing their hands and rubbing soap ... so we should save water, not only save water, but also protect the water source from pollution, because Wenzhou is in a state of pollution, and 5,500 children around the world die every day from drinking polluted water.
Students, let's save water and care for water resources! Otherwise, the last drop of water in the world will be your tears.
Since the "Five Waters Governance", I began to pay attention to the water consumption in my home and found that everyone has a "small coup" to save water.
Coup: water onions with tea.
Dad likes drinking tea. After dinner, he always likes to make a cup of green tea and drink it while watching TV. After drinking it every night, he will water the onions with the tea leaves left at home, thus saving the water for watering the onions, and the onions in the pot will grow green.
Coup 2: flush the toilet with water
I like taking a bath very much. Every time I put hot water in the shower, I should put cold water out of the water pipe first. Looking at this wasted water, I can't help thinking: what a waste, not only wasting water resources, but also wasting water charges at home. So I brought a bucket and put cold water in it. This cold water can be used for flushing toilets and washing clothes. After I told my family about this little coup, they also learned my method one after another, not only taking cold water from the toilet, but also flushing the toilet with washing water.
Coup 3: Wash rice and water the flowers
There is also a bucket in my kitchen. Every time she cooks, grandma will pour the washed rice washing water into this bucket, and sometimes she will pour the water for washing vegetables into it. Can you guess what the water is for? Let me tell you: this is the water grandpa used to water the flowers. Grandpa uses this water to water the flowers and plants planted in the yard every day. Grandpa said that Taomi water is cleaner and more nutritious than ordinary water, which can promote the growth of plants. Looking at the lush flowers and plants in the yard, our whole family praised grandpa's good method.
This is my family's water-saving coup.
In our world, water is a necessary condition for human survival. Without water, mankind will perish. In the past, the water on the earth was very good and abundant, but now the population on the earth is increasing gradually, and the water is not enough, so we should save water.
I remember when I was in the fourth grade, I kicked shuttlecock with my classmates one day and played for a while. I go to the bathroom to wash my hands. I turned on the tap and a white dragon appeared in front of me. I'll wash my hands right away. I looked at the water and found it interesting. So I blocked the faucet with my hand, and the water poured out, forming a beautiful big fountain. After a while, after I played for a while, when I walked into the bathroom again, I saw a note posted on the wall, which read "Save Water". I tore it off without hesitation and played in front of the faucet. But strangely, when I saw the beautiful "fountain" again, the water-saving note appeared on my face again. A little girl came in and looked like a sophomore. She struggled to stick a note on the wall "save water", then washed her hands and went out. I was shocked. A junior girl knows how to save water as much as possible, but I am a fourth-grade student, and I have no consciousness of saving water in my mind. Later, I gradually realized that water resources cannot be wasted. China is a country with serious water shortage in the world, and many big cities restrict water use. See who is precious.
Saving water is everyone's responsibility. As long as everyone pays attention to saving water, water shortage will stay away from us and our life will become better.
Before I came, I heard my father say that Jiaokou Reservoir is a reservoir that supplies water to our family. It is particularly meaningful to see this reservoir with my own eyes today.
After lunch, we came to the shore to do experiments. First, two beakers are filled with water, then the washing powder is put into a cup and stirred. After a while, pour phenolphthalein reagent into two cups. The glass of water into which washing powder is poured quickly turns red; The other cup didn't change color. The teacher explained to us that this is because washing powder turns ordinary water into strong alkaline water, and if it seeps into the ground, it will pollute groundwater resources. I listened and nodded hard.
After returning home, I told my mother the experimental results as soon as possible, telling her not to splash the laundry water on the ground casually, but to pour it into the sewer, so that they would be sent to the sewage treatment plant through the pipeline. After purification, they can become clean water again. Mother was very surprised and said, "How do you know so much?" Haha, because I also got the honorary certificate of "hydrophilic messenger", my parents said happily, "No wonder we know so much. Our doll has become a' hydrophilic messenger'! "
