Please cherish water resources.

On Thursday, Mr. Kong told us the lesson of "liters and milliliters" and asked us to go home and test how many milliliters of water we could drip in one minute. I turned on the tap and told my mother the time with a beaker. After a while, the time is up. I looked at the beaker and it was only 25 ml. I think if 25ml is wasted in a year (365 days), 9125ml is wasted, which is 9.125ml. According to this calculation, the national population of 654.38+03 billion will waste 654.38+08.625 billion liters a year. I was shocked when I worked out this figure. Wealth? .

I didn't realize the value of a drop of water in life before. Through this experiment, I know the importance of saving a drop of water. In my later life, I will turn off the tap after running out of water, so as not to waste domestic water. I call on everyone to cherish every drop of water with me and protect water resources.

Please cherish every drop of water.

In class today, we learned liters and milliliters, and I also learned to use liters and milliliters in my life. In class, the teacher asked us to suck 10 ml of water with a needle. I have finished smoking. I think there is little water in 10 ml. Later, I heard the teacher explain that if everyone wastes 10 ml of water, our water resources will become few or even disappear. After class, I remembered that the teacher said not to waste water, so I watered the flowers. I hope students don't waste water.

I practiced at home. A dripping faucet wastes 7 ml of water 1 minute, so 10080 ml of water is wasted 1 day, which wastes 3679200 ml of water a year (calculated by 365 days). Our school has 15 faucet. If each of us doesn't turn off the tap after using water, we can waste 15 1200ml water = 15 1.2 litres of water that day. If there are 65.438+300 million people on the earth, how much water resources will be wasted if everyone does not cherish water resources!

I appeal: Students, please cherish every drop of water!

Students, please save every drop of water!
